Maximizing Performance
All SeaI/O modules have a default baud rate of 9600. If lower latencies are required, the baud rate can be changed via the Sealevel utility, MaxSSD, included in your SeaMAX installation.
All items can be purchased from our website (www.sealevel.com) or by calling our sales team at +1 864-843-4343.
To change the baud rate, connect to a SeaI/O module using MaxSSD. If you need to change the baud rate of multiple devices, check the “Broadcast to Multiple Modules” box. Select the desired baud rate from the baud rate dropdown and click “Set Settings.” If you are connected to the modules via a COM port, you will need to reopen the COM port with the new baud rate.

Example timing values
SeaI/O-470 Baud rate: 9600 Reading 8 Digital Inputs Average Time: 32.00ms Writing 8 Digital Outputs — OFF state Average Time: 32.00ms Writing 8 Digital Outputs — ON state Average Time: 32.00ms Reading 16 Analog-to-Digital Converters Average Time: 48.01ms Writing to 2 Digital-to-Analog Outputs Average Time: 32.00ms

SeaI/O-470 Baud rate: 115200 Reading 8 Digital Inputs Average Time: 15.57ms Writing 8 Digital Outputs — OFF state Average Time: 15.92ms Writing 8 Digital Outputs — ON state Average Time: 16.21ms Reading 16 Analog-to-Digital Converters Average Time: 16.25ms Writing to 2 Digital-to-Analog Outputs Average Time: 16.26ms

Higher baud rates are more susceptible to electrical line noise. If you find that you are receiving erroneous results, try lowering the baud rate or shortening your cables.

SeaI/O Hardware Description
SeaI/O Base and Expansion Modules
Base Modules connect to the host via one of the following interfaces:
· Wireless Gateway Wireless Modbus TCP · W-Series Wireless Modbus TCP · E-Series – Ethernet Modbus TCP · U-Series – USB Modbus RTU · M-Series – RS-485 Modbus RTU · S-Series – RS-232 Modbus RTU
After the base unit is installed, up to 246 additional SeaI/O N-Series Expansion Units can be added to create an I/O network. These expansion modules interface via RS-485 and can be located local to the Base SeaI/O device or remotely located up to 4000 feet away. Local installations should use the 5″ CAT5 RS-485 pass-through cable (Part# CA239) shipped with each N-series module to connect. Remote expansion modules should use RS-485 twisted pair wiring from the base unit connected via the removable screw terminal connector.
For local installations, power to the expansion modules is supplied from the Base unit via the pass-through connectors. For remote devices, separate power is required at each expansion unit. Refer to the Power Options section of this manual for more information on SeaI/O power requirements and power supply sizing.

580PoE
The 580 differs from other SeaI/O modules in that it is provided in both E (Ethernet) and PoE (Power over Ethernet) versions. The 580PoE is powered through the Ethernet port by a PoE switch that conforms to the Power over Ethernet IEEE 802.3af standard.
In addition to using power from the Ethernet connection to power the 580, this power is made available to the expansion connector to power additional SeaI/O modules (See Power Options section of this manual). The 580PoE provides up to 7W to the expansion connector. This equates to 24V @ 291.7 mA, a little more than the Sealevel TR112 power supply.

SeaI/O | SL9049 11/2021

Power Options
Base Module Power Connection
Base modules are powered from a 9-30VDC source using either the DC jack, screw terminals or the Expansion pass-through connectors on the side of the unit. Sealevel offers several power supply choices to make connection easy (see the Accessories chapter at the end of this document).
SeaI/O Expansion Power Connection
Each SeaI/O product, including the expansion modules, contains an onboard switching regulator power supply rated for 9-30VDC. For local installations (less than 10′ apart), expansion unit power is usually supplied from the Base unit via the pass-through connectors. The number of expansion modules that can be driven from the Base unit depends on the power source and number/type of expansion units. Refer to the chart below for power requirements. For expansion modules mounted remotely (greater than 10′ apart), separate power is required at each expansion unit. The output power available on the pass- through connector can only supply a maximum of 1.2A to the additional units.
Supply power for expansion unites that are daisy-chained together should only have a single connection to an external power supply made by only one expansion unit.

Sample Power Calculation
A typical application for SeaI/O products would use one Base module and several N-series units in a local expansion configuration. In this arrangement, with power applied to the Base module through either the DC jack or screw terminal connector and passed-through to the expansion units, attention should be given to ensure the input power to the Base module is adequate.

MaxSSD Configuration & Diagnostics Utility
The Sealevel Systems configuration utility, MaxSSD, is designed to simplify the installation, configuration, and diagnostics of Sealevel I/O modules. MaxSSD is a Microsoft Windows application and has been tested with Windows 7, 8.1, and 10.
Host PC Configuration Tab
When you run the MaxSSD utility (Start All Programs Sealevel Systems SeaMAX MaxSSD Configuration Utility) it will default to the “Host PC Configuration” tab. This tab allows the user to choose the initial communication settings for the connected I/O device. The “COM Port” dropdown box allows the selection of a serial COM port (from COM1 to COM256), and Ethernet (for Ethernet and Wireless SeaI/O modules).
USB connected SeaI/O modules are installed as virtual COM ports. Using device manager, expand “Ports (COM & LPT)” by clicking on the `+’ next to the category, and locate the COM port for your device and use it in the dropdown box in MaxSSD.

Once a COM port is selected, the baud rate and parity can be selected.

The baud rate and parity of the PC must match the settings of the Sealevel I/O module to be configured. The factory default settings for all Seallevel I/O modules are 9600 baud and no parity.

To communicate with a SeaI/O Ethernet or Wireless module, select “ETHERNET” from the “COM Port” dropdown box. When Ethernet is selected, MaxSSD searches for any SeaI/O Ethernet or Wireless modules on the network and displays their IP addresses in the “Available Ethernet Devices” list box (not shown). When an IP address is selected from the list box, a socket is opened to the SeaI/O module, and it is ready for communication.
42

SeaI/O | SL9049 11/2021

Host PC Configuration Tab, Continued
If your module is set to a different subnet, you will need to type in the IP address into the IP Address field displayed in MaxSSD and press Enter. MaxSSD will try to open port 502 on that address. When the connection succeeds, it will display the “SeaIO Configuration” tab.
If no IP address is shown when using Ethernet modules, review the previous Hardware Configuration section, or proceed to the Troubleshooting section at the end of this manual.
SeaI/O Configuration Tab
Once the host computer is configured correctly, the “SeaI/O Configuration” tab becomes available. Before communicating with a SeaI/O module, the configuration utility must determine if there is an I/O module at that slave ID address, and if so, what type of module it is. This is the purpose of the Get operation. To perform a Get operation, first select the slave ID to which the module is configured. SeaI/O modules are shipped at hardware setting 0 (labeled “ADDR” on the left side of the module) and slave ID 247 by default. All other slave ID addresses (from 1 to 246) are available. However, each daisy chained SeaI/O module must have a unique slave ID address – no duplicates are allowed.

Once a slave ID is selected, click the “Get SeaI/O Module Settings” button. After a short delay, the information for that I/O module should be displayed. If no information appears, verify the slave ID, host settings, and baud rates are correct and make changes, if necessary. Check the hardware settings (on the left side of the module) and try again.

43

SeaI/O | SL9049 11/2021

SeaI/O Configuration Tab, Continued
After the Get command is executed, the “Module Description” frame will display the model type, description, firmware version number, interface, and I/O type. In the example shown, the module found at slave ID 247 is a SeaI/O-420 module with a USB (Modbus RTU) interface. The “Set Settings” and “Change Slave ID” buttons will also be enabled for this module.

After a successful Get operation, additional tabs may be displayed in MaxSSD, depending on the found device model. These tabs display device I/O and allow easy configurations for all SeaMAX supported devices.
The “Broadcast to Multiple Modules” checkbox, along with the “Set Settings” button can be used to change the baud rate and parity on multiple SeaI/O modules at once. This function only works with SeaI/O modules connected together via the pass-through connectors.
MaxSSD broadcasts a set data rate and set parity command to all devices on the RS-485 bus, but only those modules listening at the current baud rate will be able to receive and respond. For example, if you have five SeaI/O modules chained together and two are set to 9600 bps and no parity and three are set to 115.2k bps and the PC is set to 9600 bps, only the two modules set to 9600 bps will receive the broadcast set data rate and parity message.

44

SeaI/O | SL9049 11/2021

SeaI/O Configuration Tab, Continued

Ethernet (E-series) and Wireless (W-series) modules
The broadcast feature sets the Ethernet SeaI/O (E-series) module’s TCP/IP to RS-485 translation data rate independently of the SeaI/O module itself. If you set the data rate to 115.2K bps via a MaxSSD broadcast command, both the RS-485 port and the Ethernet port will respond thereafter to 115.2K bps, as expected. However, if you reset the SeaI/O module, by rotating the rotary switch clockwise one complete revolution, the RS-485 port will reset to 9600 bps and no parity, but the Ethernet port will remain unaffected. To restore communications, broadcast another set data rate and parity command (9600 and no parity) via MaxSSD.

The “Digital IO” tab of MaxSSD is displayed when using Sealevel I/O devices featuring discrete inputs and outputs. It displays the device’s current input and/or output status in an intuitive and usable manner.
When displaying SeaI/O, the “Digital IO” tab displays inputs and outputs in groupings (or banks) of eight. Therefore, a Sealevel I/O device with 16 inputs and 8 outputs would show two banks of inputs and one bank of outputs.
When banks of inputs are displayed, the status LEDs update on each of the banks automatically. This allows you to actively monitor external signals.
With a bank of outputs, the output coils can be set using the buttons below each output LED. As each coil is set, the I/O module is read. The corresponding status LED in the “Digital IO” tab indicates the state of the coil. In the example below, a SeaI/O module with 16 Reed relays is shown.

A/D Inputs Tab
The “A/D Inputs” tab displays the current state of the analog-to-digital channels for Sealevel I/O devices that feature A/D inputs. Settings are provided for both device wide and per-channel configuration.

The “Device Configuration” selection drop-box adjusts the arrangement and function of the A/D input channels. Input channels are displayed as banks (groups of eight). Each channel is range configurable via the voltage range dropdown list. Both the channel voltage range and device-wide configuration are set on a dropdown list. There is no need to save your settings they are automatically saved to the device as you select the various configuration options.
“10x Hardware Gain Enabled” checkbox Indicates whether or not the onboard hardware gain jumper is currently set. This option is not user configurable it only reflects the status of the onboard hardware jumper settings. Set the hardware jumper to enable this functionality, which allows smaller voltages to be measured more accurately (e.g., a 0-1V input signal can be measured more accurately by enabling the 10x hardware gain jumper and setting the SeaI/O-470 A/D input channel for 0-10V range).
“Show Hexadecimal Values” checkbox Displays the values returned by the A/D converter as a hexadecimal value without converting the values to engineering units (i.e., Amps or Volts)

47

SeaI/O | SL9049 11/2021

D/A Outputs Tab
The “D/A Outputs” tab is useful for manually setting the digital to analog output voltages on applicable Sealevel I/O devices with D/A channels. A preliminary diagnostics utility (see following page) has been provided to verify proper hardware functionality.
The D/A outputs of the SeaI/O-470 are factory set for 0-10V. To configure the D/A outputs for 0-5V, you will need to open the enclosure and set the correct jumpers. Refer to the Hardware Configuration section of this manual for instructions on opening the enclosure and accessing the correct jumpers.
To adjust a particular channel’s output voltage, drag the slider until the desired voltage is displayed in the window on the right side. Also, you may type the desired voltage directly into the voltage display and then confirm your entry by pressing the `Enter’ key on your keyboard.

The output voltage will not change until the `Enter’ key is pressed or you have clicked on the window anywhere outside of the text entry field.

A/D & D/A Diagnostics
To check basic functionality of both the A/D and D/A converters, press the “Diagnostics Utility” button on the “D/A Outputs” tab (shown on the previous page) and then press the “Start” button, as shown below. Any errors will be shown in the “Results” pane. If any errors occur, please contact technical support for further help.

Converting A/D & D/A Values
To properly use the values returned from the SeaI/O-470 module’s A/D channels, the application program must convert the returned values to engineering units (voltage). Likewise, the application program must output the correct value to the I/O module’s D/A outputs to generate the desired voltage.
The conversion formulas will vary depending on how the I/O module is configured. The formulas and their uses are covered in detail in the interactive documentation located on the Sealevel website at https://www.sealevel.com/seamax-api-documentation/. For ease of use, SeaMAX functions to convert A/D and D/A values have been provided. Use of these functions is also detailed in the SeaMAX API Documentation.

Troubleshooting – SeaMAX
By using this software and following these simple steps, most common problems can be eliminated without the need to call Technical Support.
1. Read this manual thoroughly before attempting to install the adapter in your system. 2. Uninstall any previous versions of the SeaMAX software before installing any new versions. 3. Install SeaMAX Software Suite first, before connecting any Sealevel I/O devices. After installing the
software then proceed to adding the hardware. This places the required installation files in the correct locations. After installing the software, proceed with adding the hardware.
4. Confirm that all screw terminal connections are correct and secure and that the correct cables are being used, including network cables (crossover vs. patch cables).
5. You can use standard network patch cables (straight-through cables) to connect SeaI/O modules together via the pass-through connectors on the left side of the module. Crossover cables should never be used to connect two or more SeaI/O modules together. Crossover cables should only be used to connect an Ethernet SeaI/O module to a host without going through an Ethernet hub or switch.
6. On SeaI/O modules, verify that the device address (slave ID) is properly set. Refer to the Hardware Configuration section of this manual for instructions on setting the device slave ID.
7. Use the MaxSSD utility to verify proper installation. MaxSSD is designed to simplify the installation, configuration, and diagnostics of Sealevel SeaI/O modules.
8. If the SeaI/O modules only sometimes respond to a Get operation or return invalid data, you may have termination improperly set. Refer to the Hardware Configuration section of this manual for instructions on properly setting line termination and pull-up/pull-down resistors.
9. Refer to the Troubleshooting Ethernet Modules section on the following page for additional steps regarding Ethernet (E-series) SeaI/O modules.
If these steps do not solve your problem, please call Sealevel Systems’ Technical Support, 864-843-4343. Our technical support is free and available from 8:00AM-5:00PM Eastern Time, Monday through Friday. For email support contact: support@sealevel.com.

SeaI/O | SL9049 11/2021

Hardware Configuration
Setting Device Address (Slave ID)
Before configuring SeaI/O modules using MaxSSD, you must first select a device addressing method. Next, you must properly set termination and pull-up/pull- down resistors. Finally, you must configure the SeaI/O modules one at a time before MaxSSD and any subsequent applications (using the SeaMAX API) will be able to successfully communicate.

SeaI/O modules have a rotary switch, labeled “ADDR,” located on the left side of the device that is used to set the device address (slave ID). The default position for all SeaI/O modules is position “0” (zero). Each SeaI/O module must be set to a unique slave ID in order to properly communicate with the host device, which can be a computer or Modbus device. The slave ID can be set by hardware using the rotary switch, which is recommended for most users. The slave ID can also be set in software by leaving the rotary switch at position “0” and using MaxSSD to set the slave ID. The rotary switch has three functions:
· Set Address (slave ID) via Hardware If the rotary switch is set to a position between “1” and “15” (F). The SeaI/O module will then always respond to commands issued at that slave ID. This is useful when there are fewer than 16 SeaI/O modules in a chain and the slave ID is not required to change. This method is recommended for most users.
· Set Address (slave ID) via Software If the rotary switch is left in the “0” (zero) position, the SeaI/O module uses a default slave ID of 247 for communications. By using MaxSSD (or the SeaMAX libraries), it is possible to set the slave ID to a software address between 1 and 247. This is useful when there are more than 16 SeaI/O modules in a chain, or when the slave ID of a module needs to be frequently changed.
· Hardware Reset If you have an existing SeaI/O module set to an unknown slave ID or baud rate, you may wish to reset the device. If the rotary switch is rotated clockwise one full revolution, the SeaI/O module will be reset to factory defaults (slave ID 247, 9600 bps, and no parity).

52

SeaI/O | SL9049 11/2021

Hardware Configuration, Continued
A Hardware Reset will not reset the communication rate of Ethernet (E-series) and Wireless (W-series) modules. Rotate the rotary switch clockwise one full revolution, and then use the MaxSSD utility to broadcast a set baud rate command to 9600 bps and no parity.
Setting Termination & Pull-Up/Pull-Down Resistors

A “stack” or “chain” of SeaI/O modules, connected via the pass-through connectors or screw terminals on the left side of the enclosure, communicates via an RS-485 bus, which must be properly terminated to work correctly. A set of three dipswitches is located on the left side of enclosure, next to the “ADDR” rotary switch. These switches control line termination and the RS-485 pull-up and pull-down resistors. The pull-up and pull-down resistors ensure that the input ports are at a known state when not being driven by the RS-485 line. In most cases, all three of the dipswitches on each SeaI/O module should be in the down position, except the two end modules. The first and last SeaI/O modules in the chain should have all three dipswitches in the up (enabled) position.
Make sure that only the first and last SeaI/O modules have line termination enabled (up position). Improper termination settings can result in invalid data or communication failures.
Configuring the “Base” SeaI/O Module
Once the SeaMAX Software Suite has been installed successfully and you have decided which address (slave ID) method you intend to use, start by connecting the first SeaI/O module to your computer. This will be referred to as the “base” module. If you are chaining multiple SeaI/O modules together, only one SeaI/O module in the chain can be the “base.” All other SeaI/O modules connected to the “base” module are referred to as expansion modules. Multiple “base” modules can be directly connected to a host computer, but expansion modules must be connected (daisy chained) to a “base” module.

53

SeaI/O | SL9049 11/2021

If you are configuring an Ethernet (E-series) or Wireless (W-series) SeaI/O module, skip ahead to the Configuring an Ethernet Module or Configuring a Wireless Module sections for specific information on installing those modules.
For all other SeaI/O modules (U-series, S-series, or M-series), locate the COM port by expanding the `Ports’ list in Windows Device Manager.
Start MaxSSD (Start All Programs Sealevel SeaMAX MaxSSD) and choose the correct port (IP address or COM port) to communicate with the “base” module. Ensure a successful Get operation (refer to the MaxSSD section on the following pages for more information). Set the slave ID of the “base” module using the rotary switch or software selection method discussed in the Setting Device Address section on the previous pages. This guarantees that any expansion modules connected next will not conflict with the “base” module. Perform another Get operation to verify that you can communicate with the “base” module at the new slave ID.
Configure SeaI/O modules one at a time. Set the address to a hardware slave ID other than “0” or a software slave ID other than 247, which avoids device conflicts during setup.
After the “base” module is successfully communicating via MaxSSD, you can proceed with adding SeaI/O expansion modules (N-series) one at a time as required.
If the “base” module does not respond as expected, turn the rotary switch (ADDR) clockwise one full revolution to reset. Configure the PC to communicate at 9600 bps and no parity and then try again.
Configuring N-Series Expansion Modules
Once you have successfully connected and communicated with a “base” module, you can begin adding expansion modules (N-series). Connect a single expansion module to the “base” module via the RJ45 passthrough connectors or screw terminals on the left side of the enclosure. Expansion modules include a convenient 5″ interconnect cable (Part# CA239) to simplify daisy-chaining SeaI/O modules together. Alternatively, you can use standard network patch cables to chain expansion modules to a “base” module.
The RJ45 pass-through connectors on the left side of SeaI/O modules are not Ethernet connectors. Do not connect the ports to Ethernet enabled devices else damage to Ethernet devices will result.

54

SeaI/O | SL9049 11/2021

Ensure a successful Get operation (refer to the MaxSSD section on the following pages for more information). Set the slave ID of the expansion module using the rotary switch or software selection method discussed in the Setting Device Address section on the preceding pages. Perform another Get operation to verify that you can communicate with the expansion module at the new slave ID. Continue adding expansion modules (N-series) one at a time, until all modules have been successfully daisychained together and respond to a Get operation in MaxSSD. Once all SeaI/O modules are configured and communicating successfully, they are ready to communicate with your application.
Configuring a Wireless (W-Series) Module or Wireless Gateway
Begin by connecting power to the wireless device. The STAT LED will blink twice to indicate that the unit is powered up in Access Point mode and is ready to be configured to work with your wireless network. In the case of a SeaI/O wireless module, this module will become the “base” module.
All SeaI/O wireless devices ship in Access Point mode. This allows you to directly connect to the device for configuration using any mobile device, laptop, or desktop computer with a wireless 802.11b/g/n compatible adapter.
Basic Wireless Configuration Overview
1. Using a wireless enabled computer or mobile device, connect to the device. Once connected, open a browser, and navigate to the Profile page.
2. Create a network profile for your network wireless access point.
3. Restart the device.

Wireless Configuration Details
The detailed configuration instructions that follow are for Windows 10. The basic instructions for Windows 7 are the same. If you have any questions, please contact Sealevel technical support at support@sealevel.com.
Begin by clicking on the network icon in the system tray to show the list of available wireless access points (Figure 3). Connect to the access point named “SeaIO-27XXXX”1. By default, the access point is unsecured with no password required to connect. The module assigns an IPv4 address to your client via DHCP. The STAT LED will light up to indicate a client has connected. (Only one client may be connected to the SeaI/O wireless device’s access point at a time.)

Figure 3: Connecting to SeaI/O wireless device access point
Open a web browser (such as Microsoft Edge) and navigate to the device’s configuration web page. Depending on the platform you are using, the address is in one of the following formats:
The IPv4 address, e.g., http://192.168.1.1/ (all platforms) The NetBIOS name, e.g., http://SeaIO-27xxxx/ (Windows only) The mDNS name, e.g., http://SeaIO- 27xxxx.local/ (iOS only) The NetBIOS/mDNS name is equivalent to the device name, which is configurable on the Configuration page. Note that the terminating slash is required. Enter the username and password to access the web page (Figure 4). The default username and password are both “seaioadmin.” It is highly recommended that you change the username and password from the defaults.

1 Here and elsewhere in this manual, 27XXXX refers to the last 6 characters (i.e., last 3 octets) of the device’s unique MAC address, which is located on the sticker.

Device
The Device page displays all current configuration parameters, an administration section, and a section to update the wireless adapter’s firmware. The administration section includes buttons to restart the device and reset to factory settings. Use the Restart Device button as a convenient way to remotely restart the device. You will be required to restart the device after making any changes to network settings from this web interface. This button is equivalent to power-cycling the device using the physical reset button or unplugging and restoring power. Use the Factory Settings Reset button to revert all network and communication settings to their factory defaults. This is equivalent to holding the physical configuration button for 10 seconds. If the “Enable firmware update of device” feature is enabled (see the Configuration Page), the Firmware Update section is displayed and allows for the wireless adapter’s firmware to be remotely updated. Selection of a new firmware file is done with the Browse button, after which the Upload button starts the update process. A pop-up dialog box will appear after the upload is complete which, if the upload is successful, will prompt you to click a Restart button to complete the update.

Configuration
The Configuration page includes the options to change the device name and HTTP authentication settings, as well as enable or disable firmware update-related features.
The device name is reflected in the NetBIOS and mDNS name mentioned in the first-time setup process. Changing this setting requires a device restart.
Change the HTTP Authentication settings to change the username and password required to access the internal web pages.
The Firmware Update settings allow for the local device (the wireless adapter) and Modbus-connected SeaI/O slave device firmware update features to be enabled/disabled. Both features are disabled by default for security. To allow updating of the local device (the wireless adapter itself), check the “Enable firmware update of device” checkbox and click Apply. Note that the Firmware Update panel on the Device page will be shown or hidden to reflect the value of the “Enable firmware update of device” setting. The “Enable firmware update of slave devices via MaxSSD” setting allows the wireless adapter to pass along firmware updates to any SeaI/O slave device connected via RS485 to the base/master SeaI/O device when using MaxSSD. Any change to the Firmware Update settings take effect immediately after clicking the Apply button; no restart is required.

Configuring an Ethernet (E-Series) Module
This section applies only to Ethernet (E-series) SeaI/O modules. For all other SeaI/O modules, refer to the Configuring a “Base” SeaI/O Module and Configuring Expansion Modules sections on the previous pages.
Verify that SeaMAX software has been installed successfully and that an Ethernet SeaI/O module is connected directly to your computer using the yellow crossover cable supplied with your module. This module will become the “base” module.
All Ethernet SeaI/O modules are shipped with DHCP enabled. When you first connect an Ethernet SeaI/O module to the network, the status LEDs on the front of the module will blink while it searches for a DHCP server. Once it receives an IP address, the status LEDs will remain on.
If no DHCP server is available, the Ethernet SeaI/O module will default to a random IP address in the range 169.254.x.x. To discover the SeaI/O module’s IP address, start the Ethernet Config utility (Start All Programs Sealevel SeaMAX Ethernet Config) installed with SeaMAX.

Click on the “Search for SeaI/O Devices” button and the `Available SeaI/O Devices’ pane should refresh with any Ethernet or Wireless SeaI/O modules that are found on the network. Select one of the modules in the list by clicking on it. You can update the settings in the Device Network Settings pane and then confirm these changes by clicking the “Apply Changes” button. The module list should refresh, indicating that your changes were successful.

Configuring an Ethernet (E-Series) Module, Continued
If the module does not change or respond, the PC and the module may be on different subnets. Proceed to the “Resetting An Ethernet SeaI/O Module” section on the following page.
Start MaxSSD (Start All Programs Sealevel SeaMAX MaxSSD) and choose the correct IP address to communicate with the “base” Ethernet SeaI/O module. Ensure a successful Get operation (refer to the MaxSSD section of this manual for more information). Set the slave ID of the “base” Ethernet SeaI/O module using the rotary switch or software selection method discussed in the Setting Device Address section on the previous pages. This guarantees that any expansion modules connected next will not conflict with the “base” module. Perform another Get operation to verify that you can communicate with the “base” Ethernet SeaI/O module at the new slave ID.
Configure the SeaI/O modules one at a time. Set the address to a hardware slave ID other than “0” or a software slave ID other than 247, which avoids device conflicts during setup.
After the “base” Ethernet SeaI/O module is successfully communicating via MaxSSD, you can proceed with adding SeaI/O expansion modules (N-series). Refer to the Configuring Expansion Modules section on the previous pages.
Resetting an Ethernet SeaI/O Module
An Ethernet SeaI/O module may become no longer visible in the module list in the Ethernet Config utility if the Ethernet SeaI/O module has been configured to use a different subnet than the host computer. In other cases, the Ethernet SeaI/O module does not appear in the module list due to a DHCP discovery failure. In either case, clicking on the “Recover Module” button (see image on previous page) in the Ethernet Config utility will bring up the “Module Reset” window shown below.

66

SeaI/O | SL9049 11/2021

Before recovery begins, make certain that the PC and Ethernet SeaI/O module are on the same network segment they should be connected with an Ethernet crossover cable, through a hub, or through a non-routing switch. Ethernet SeaI/O modules are shipped with both an Ethernet patch cable (blue) and an Ethernet crossover cable (yellow).
Enter the MAC address found on the label on the bottom of the SeaI/O enclosure. A MAC address is made up of six pairs of hex digits separated by dashes (i.e., xx-xx-xx-xx-xx-xx). While entering the MAC address, the indicator to the right of the field will turn red if the MAC address entered is invalid. Once a MAC address is successfully entered, the indicator light will turn green, and the “Network Settings” options will be enabled.
Contact your network administrator if you are unsure of the proper network settings to choose. If a DHCP server is available, select the “Enable DHCP Configuration” checkbox. Otherwise, complete the network settings and click the “Recover Module” button to complete the configuration changes.
Proceed with configuring expansion modules, explained in the previous section.

Module Firmware Upgrading
This section describes the process for upgrading the firmware of the expansion SeaI/O modules. The Wireless modules contain an additional wireless networking engine that may be updated as well. See Configuring a Wireless Module | Device section above for directions on upgrading the Wireless engine subsystem of Wireless modules.
If a newer version of expansion module firmware is available, it is possible to upgrade the firmware in the unit. This can be done through the same port that is used to do normal communications with the unit. The exception is when the unit is used with a wireless connection. In this case, the unit must be directly connected to the programming computer.
Since there is required interaction between the programming PC and the SeaI/O module being programmed, this must be done in a situation where only one SeaI/O module is connected to the programming computer.
Once you have the new programming file this will be a file with a name similar to your SeaI/O model number with an extension of “.hex.” As an example, it you have a SeaI/O 420 style module, the programming file name would be “420E.hex”.
When you are provided the file to be programmed, you will also receive the programming program. The name of this program is SeaIOCU.exe.
Procedure
Since SeaI/OCU.exe must be executed from a command prompt, the easiest way to use it is to copy SeaI/OCU.exe and the hex file (in this example it is 420E.hex) to a subdirectory you create. For this example, we will create a subdirectory called c:SeaIOcu.
Click on Start, then click Run and type “cmd” (without the quotation marks and hit enter. You will then see a command prompt (c:documents and settingsname>).
Type
Cd SeaIOcu and then press Enter
At this point, we assume the SeaI/O 420 unit is set for 9600 baud and address 247 (the default if the rotary switch is in position 0).
If you are connected either through a RS-232, RS-485, or USB connection then when the command calls for nnn, you substitute your com port number. Note that it MUST be 3 digits. Therefore, if your com port is com5, you will enter 005. The command for this is therefore:
SeaIOcu /c=005 /b=9600 /a=247 420e.hex
If you are connected through an Ethernet connection then when the command calls for iii.iii.iii.iii you substitute the unit’s IP address. Note that each group of numbers MUST be 3 digits. Therefore, if your IP address is 192.168.42.11, you will enter 192.168.042.011. The command for this is therefore:
SeaIOcu /i=192.168.042.011 /a=247 420e.hex

69

SeaI/O | SL9049 11/2021

The first thing the SeaI/O unit will do is to erase all of its flash memory (with the exception of a small loader for the firmware). It will then start flashing all three lights rapidly indicating it requires downloading. Once the download starts, one light will flash as data is downloaded. Once the download is complete, the green light will remain on. At this point, simply unplug power to the unit and when power is re-applied, you should be operational with the new software. In the event something about the download failed, the red light should stay on. In this case, simply power down the unit and power it back up. It should now be flashing all three lights rapidly. Simply perform the SeaIOcu command as described above.
The above should only be performed if you (1) really feel the update is required and (2) you feel confident in your ability to perform the update. Once the firmware has been erased, you must either be able to reprogram it locally or send it back to SeaLevel Systems, Inc. for reprogramming.
Disabling the Rotary Address Switch & Limit Software Address Range Selection
Disabling the Rotary Address Switch and Limiting Software Address Range Selection is not available on older SeaI/O units (Before Firmware Version 2). In addition, the following modules do not support it.

As noted earlier, rotating the rotary switch from a non-zero address to the address zero position will reset the unit to the default state of address 247 and 9600 baud. There are many situations where this is not desirable. In the event you wish to disable the rotary switch or simply limit the range of software selectable addresses that may be set, you can do so by sending the “WriteMultipleRegisters (function 0x16)” MODBUS command to the unit. Address 300 (decimal) should contain the low order byte of the lowest address the unit will accept. Address 301 will contain the high order byte. Once this command has been issued, the rotary switch will be completely ignored by the firmware.
To reset the unit to “normal” operation, you can issue the MODBUS “Broadcast Reset Message (function 0x19).
This setting can also be configured through MaxSSD under the “Range Configuration” tab, shown below on the next page.

Limiting Expansion Port Communications Data Rate Selection
Limiting Expansion Port Communications Data Rate Selection is not available on older SeaI/O units (Before Firmware Version 2). In addition, the following modules do not support it:
· 462 · 463 · 470
There are situations where it is desirable to limit the range of allowable data rates or lock down the unit to one specific data rate. This can be performed by sending the “WriteMultipleRegisters (function 0x16)” MODBUS command to the unit. Address 302 (decimal) should contain the low order byte of the lower data rate the unit will accept. Address 303 will contain the high order byte. Note that this command does not cause the rotary switch to be ignored. Therefore, the rotary switch can be used to reset the defaults range and set the data rate back to 9600. If this is not desirable, then you can either set the data rate limitation and then set the address range to prevent the rotary switch from resetting to defaults or you can write to locations 300 through 303 in one “WriteMultipleRegisters” command.
To reset the unit to “normal” operation, you can issue the MODBUS “Reset Range Settings” (function 0x19).
This setting can also be configured through MaxSSD under the “Advanced” tab, shown below.

D/A Settings
The (E1) and (E2) jumpers (shown in the orange boxes on the previous page) configure the D/A outputs for 05V or 0-10V. Both channels can be configured independently. The D/A outputs do not support negative voltages. You must also set the correct output voltage in your application or MaxSSD. Refer to the SeaMAX Application Suite section of this manual for help configuring software to work with the SeaI/O-470.
A/D 10X Gain
The A/D 10X gain (E3) jumper (shown in the green box on the previous page) is disabled at the factory. Position the hardware jumper on both pins to enable this functionality, which allows smaller voltages to be measured more accurately (e.g., a 0-1V input signal can be measured more accurately by enabling the 10x hardware gain jumper and setting the SeaI/O-470 A/D input channel for 0-10V range). You can also set the A/D input channel for 0-5V to sense voltages smaller than 0.5V.
When the jumper is enabled, the “10X Hardware Gain” checkbox will also be enabled on the A/D Inputs tab in MaxSSD. Refer to the SeaMAX Application Suite section of this manual for information on using MaxSSD.
A/D and Current Loop Dipswitches
The (SW3) and (SW4) dipswitches (shown in the yellow box on the previous page) configure the A/D inputs for current loop mode and are disabled at the factory. Since current loop mode is differential, the corresponding dipswitch on both (SW3) and (SW4) should be properly set (e.g., CH1′ on both dipswitches needs to be set toON’ to enable current loop mode).
SW3 enables the current-loop sensing resistor
SW4 ties the other half of connection to ground

Thermistor Switch location
On the SeaI/O-570 PCB, switch 5 (SW5) allows each of the eight A/D channels to be individually configured for a thermistor by moving the corresponding channel selector (1-8) to the “ON” position. This will apply a bias voltage of +5V through a 10K Ohm resistor. Connect the thermistor between the input and ground reference on the SeaI/O-570’s terminal block connector. This will create a voltage divider and as the resistance of the thermistor changes so will the voltage read by the application. Please reference the data sheet of the chosen thermistor to calculate the measured temperature.

Wiring Options
SeaI/O Pass-Through Connector
All SeaI/O modules include two RS-485 pass-through connectors on the left side of the unit that are internally connected to the same pins on the screw terminals. This offers two convenient options for adding additional expansion modules. For connecting several SeaI/O modules together in a “stack,” all N-series expansion modules ship with an expansion and strap kit (Part# KT122) that includes four metal straps, four #4-40 screws, and a 5″ RJ45 RS-485 interconnect cable (Part# CA239). The metal straps allow you to securely connect multiple SeaI/O modules together. The interconnect cable can be used to connect SeaI/O modules together via the RJ45 pass-through connectors, providing an easy method to cascade RS-485 signals and power from one module to the next. For expansion modules that are less than ten feet from a base unit, a standard RJ45 CAT5 patch cable (“straightthrough”) may be used. For SeaI/O modules greater than ten feet apart, use twisted-pair cable connecting the data lines to the screw terminals instead. If RJ45 connectors are preferred, be sure to connect only the data lines (pins 4 and 5).
When using standard CAT5 patch cables to connect modules less than ten feet apart, ensure the cables are wired “straight-through.”
Do not connect network crossover cables to the pass-through connectors, else damage to equipment may result.
Modules greater than ten feet apart must have separate power supplies. Refer to the Power Options section of this manual for recommendations.

Floating Signal Sources
A floating, non-referenced signal source is a signal that is not connected in any fashion to the building ground system but rather has an isolated ground reference point. Examples of floating signal sources are outputs of transformers, thermistors, battery-powered devices, and opto-isolator outputs. To measure these devices the ground reference point must be connected to the analog ground reference of the SeaI/O-570 as shown in the above schematic. Without this connection, the signals will float, and an accurate measurement is not possible. The SeaI/O-570 is configured to measure floating, non- referenced signals by default.

91

SeaI/O | SL9049 11/2021

Ground-Referenced Signal Sources
A ground-referenced signal is a signal that is connected in some fashion to the building system ground and therefore is already connected to a common ground point with respect to the SeaI/O-570. Examples would be non-isolated outputs of instruments and devices that are connected to the same building power system as the SeaI/O-570. The difference in ground potential between two devices connected to the same building power system is typically 1mV to 100mV and can be much higher with improper power system grounding. This ground potential difference can show up as a measurement error without using the proper measurement connections. The above connection scheme is designed to eliminate this ground potential difference from the measurement.
