160 SERIES – 32 CHANNEL TTL DIGITAL INTERFACE
Control and monitor up to 32 channels of buffered drive digital I/O with the eI/O-160. The module addresses the 32 channels of I/O as four eight-bit ports, each programmable as input or output. Use a standard 50pin IDC ribbon cable to connect an industry standard relay rack for PC based control and automation of equipment including sensors, switches, security control systems, and other industrial automation systems.
The eI/O-160 50 pin digital interface is pin compatible with the Sealevel SeaDAC Lite 8126 and will accept 8126 accessories.

Power Requirements

Inputs

**Outputs ***

 The eI/O-160 is designed to work with industry standard solid-state relay racks that expect negative logic to operate. The eI/O-160 itself uses positive logic for inputs and outputs.

The eI/O-160 addresses the 32 channels of buffered drive digital I/O as four eight-bit ports. Each port is programmable as input or output. The I/O channels are accessed via an industry standard 50-pin header connector. Use a standard 50-pin 0.100″ pitch IDC  ribbon cable to connect to an industry standard relay rack, terminal block (Item# TB07), or relay rack simulation module (Item# TA01). Each channel can sink up to 64mA or source up to 32mA. All channels combined cannot exceed a total output of 350mA.

Relay racks with less than 32 channels and the TA01 simulation module expect all even pins to be commons. When using the TA01 or relay racks with less than 32 channels, set Port D as an input to avoid shorting the outputs to ground through the relay rack.

Relay modules vary in their performance and characteristics. Discrete output modules available from typically draw 10mA each but may draw 27mA in a worst case scenario. This actual current draw and the number of modules used will determine how many can  be powered by the +5V on pin 49 of the 160E/POE. Contact your relay vendor to determine the actual current requirements.

Many relay racks allow the modules to be powered by an external power supply. This can allow more higher powered devices to be used. In this case, a jumper on the relay rack must be disconnected so the external power supply does not back power the  160E/POE via pin 49. Contact the manufacturer of the relay rack to determine how this jumper can be disconnected.

50-PIN HEADER CONNECTOR
The eI/O-160 has the following pin out which is compatible with a wide variety of industry standard solidstate relay racks.

TTL LOGIC & EXAMPLE CIRCUITS
The eI/O-160 uses 74ABT245B octal bidirectional transceivers to provide TTL input/output capabilities.
Each bit is pulled to +5V through a 10K Ω pull-up resistor to insure each bit is at a known state when not driven. If an input is not connected to ground, it will read as a one (1) due to the 10K Ω pull-up resistors on each port.

170 SERIES – 8 ANALOG INPUTS /2 OPTICALLY ISOLATED DIGITAL INPUTS/2 SOLID STATE RELAY OUTPUTS
The eI/O-170 provides 8 analog inputs 2 optically isolated digital inputs and 2 SPST Form A solid state relay outputs. Analog inputs can be configured via software as 8 single ended inputs or 4 differential inputs.
Voltage ranges are software configurable as 0-5V, 0-10V, -5V to 5V and -10V to 10V to provide optimal accuracy depending on application. Digital inputs are pre-biased internally and current limited so a connection to ground is all that is necessary to activate the  input. The inputs also provide 1000V isolation to digital ground. Solid state relays can switch up to 60VDC at 2.5A.

Analog Inputs

| 8 single ended or 4 differential
---|---
| 0V-5V, 0V-10V, -5V-5V, -10V-10V
| 12bit
| 100kΩ

The analog inputs can operate as 8 single ended inputs or 4 differential inputs. See wiring diagrams below for terminal numbering and channel pairing.

Relay Outputs

Digital Inputs

The optically isolated digital inputs featured on the 170 are designed unlike the opto-inputs found on many other Sealevel products. The 170 provides a voltage to the opto input, which is current limited with a 330 ohm resistor. Connecting either of the inputs to  a common pin will cause current to flow through the optoisolator, activating the input.
The inputs were designed this way, so the end-user does not need to provide a voltage source. A simple external contact closure is all that is required to trigger the input.

Two common pins are provided with the optically isolated inputs for convenience; however, both common pins of the inputs are electrically equivalent on the board.

The diagram below shows how the inputs are intended to be used.

Power Options

eI/O Power Connection
eI/O standard units are powered from a 9-30VDC source using the screw terminals on the side of the unit. Sealevel offers several power supply choices to make connection easy (see the Optional Items section in the beginning of this document).

DC supply wiring must be made in accordance to all local and national electrical codes. In particular, DC supply wiring must include overcurrent protection which limits the maximum fault current to 8A.

The eI/O PoE units are Class 0 (IEEE 802.3af-2003) Power over Ethernet devices. This allows power and data to be transferred over a single CAT5 cable and eliminates the need for an external power supply. With PoE, power can be supplied by power sourcing  equipment including PoE switches (midspans) and injectors.

MaxSSD Configuration & Diagnostics Utility
The Sealevel Systems configuration utility, MaxSSD, is designed to simplify the installation, configuration, and diagnostics of Sealevel eI/O and Sea I/O modules. MaxSSD is a Microsoft Windows application and has been tested with Windows 2000, XP, Vista, and Windows 7.

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 Sealevel I/O modules).

To communicate with an eI/O 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.
If your eI/O 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 and your eI/O module is on the same subnet as the MaxSSD computer, 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 an eI/O module, the configuration utility must determine if there is an I/O module, and if so, what type of module it is. This is the  purpose of the Get operation.

The eI/O modules will respond to any Slave ID, so just use the default.

Click the “Get SeaIO Module Settings” button. After a short delay, the information for that I/O module should be displayed. If no information appears, verify that the host settings are correct and make changes if necessary.

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 1 is an eI/O 170 module with a PoE (Modbus  TCP) interface.

After a successful Get operation, additional tabs may be displayed in MaxSSD, depending on the device model found. These tabs display device I/O and allow easy configurations for all SeaMAX supported devices.

DIGITAL I/O TAB
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 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, an eI/O module with  4 optically isolated inputs and 4 Form C 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 up to 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.
“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).

CONVERTING A/D VALUES
To properly use the values returned from the eI/O-170 module’s A/D channels, the application program must convert the returned values to engineering units (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 http://www.sealevel.com/software/SeaMAX/. For ease of  use, SeaMAX functions to convert A/D values have been provided. Use of these functions is also detailed in the SeaMAX Software Manual.

TROUBLESHOOTING SEAMAX
Following these simple steps can eliminate most common problems.

1. Read this manual thoroughly before attempting to install the device in your system.
2. Uninstall any previous versions of the SeaMAX software before installing any new versions.
3. 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).
4. Use the MaxSSD utility, included in the SeaMAX software suite, to verify proper installation. MaxSSD is designed to simplify the installation, configuration, and diagnostics of Sealevel SeaI/O modules.
5. Refer to the Troubleshooting Ethernet eI/O Modules and Factory Resetting Ethernet eI/O modules sections on the following page for additional steps regarding eI/O modules.
6. If these steps do not solve your problem, please contact Sealevel Technical Support. Our technical support is free and available from 8:00 AM – 5:00 PM EST, Monday through Friday. You can contact Technical Support via email at support@sealevel.com  or by phone at +1 864-843-4343.

TROUBLESHOOTING ETHERNET EI/O MODULES
Problem: The eI/O module starts up with a strange IP address (i.e., 192.168.42.253).
All eI/O modules are shipped with the static IP address 192.168.42.253. To change, connect the module directly to a PC using the supplied network cable and set the PC’s network settings to place both the eI/O module and PC on the same subnet. Adjust the eI/O  module’s IP address and subnet mask using the Ethernet Config utility (Start → All Programs → Sealevel Systems →SeaMAX →Ethernet Configuration Tool) installed with SeaMAX. Then restore the PC’s network settings.

Problem: The eI/O module is visible in Ethernet Config, but the network settings cannot be changed.
The eI/O module is most likely on a different subnet than the PC. The PC’s IP address and Netmask must be altered to place both the eI/O module and the PC within the same subnet. Contact your network administrator for assistance.

Problem: The eI/O module does not show up in Ethernet Config.
eI/O modules are discovered via a UDP broadcast. Verify that any firewall software, such as Windows Firewall, ZoneAlarm, etc., or router settings that would hinder UDP transmissions are disabled.
It is also possible that the eI/O module may not be discovered if the PC and module are on separate subnets. This may occur if the module’s IP address is configured outside the range of the PC’s subnet. It can also occur during a failed DHCP discovery. In either  case, the “Recover Module” button in Ethernet Config utility may be used to recover the device. Refer to the Hardware Configuration section of this manual for more information.

FACTORY RESETTING ETHERNET eI/O MODULES
If the unwanted behavior persists, the entire configuration of an eI/O module can be reset to its original factory state so that it resumes the original shipping behavior and configuration.

1. Disconnect power to the module. For PoE models this is the RJ-45 network connection.
2. If your eI/O model’s reset button is accessed from inside, unscrew the four screws on the bottom and lift the module’s top off from the side opposite the Power LED.
3. Press and hold the reset button next to the RJ-45 network port.
4. While continuing to hold the reset button, reconnect power to the module and wait 10 seconds. If you release the button early, disconnect power and try again from step 3. If you have a non-PoE model, using a switched power strip to control the power  connection to the module may make this step easier.
5. Release the button.

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 8:00 A.M.- 5:00 P.M. Eastern Time Monday through Friday.

Hardware Configuration

Configuring Ethernet
All eI/O modules are shipped configured to static IP address 192.168.42.253. If this IP address will not work on your network or it is already used, you can change the IP address using the Ethernet Config utility.
Verify that SeaMAX software has been installed successfully and that an eI/O module is connected directly to your computer using the network cable supplied with your module. Next you need to configure the network adapter. Specifics details of this  configuration vary with operating systems, but in general you need to change the IP address of the network adaptor to which your eI/O module is connected. The IP address of the adaptor should be 192.168.42.254 (the last octet can be anything but 253).
Start the Ethernet Config utility (Start →All Programs →Sealevel Systems →SeaMAX →Ethernet Configuration Tool) 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 and any eI/O modules that are connected to any network(s) attached to your computer. Select one of the devices in the  list by clicking on it. You can update the network settings for that device in the Device Network Settings pane and then confirm these changes by clicking the “Apply Changes” button. The device list should refresh, indicating that your changes were successful.  Checking the “Enable DHCP Configuration” box will configure the device to get an IP address from the DHCP server for your network once the device is connected to that network. Once connect, refresh the device list using the ‘Search for SeaIO Devices’ button  to get the device’s IP address.

If an eI/O module has been configured to DHCP mode, when you connect it 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.
Now start MaxSSD (Start →All Programs →Sealevel Systems →SeaMAX →MaxSSD Configuration Utility) and choose the correct IP address to communicate with the eI/O module. Ensure a successful Get operation (refer to the MaxSSD section of this manual  for more information).

RESETTING AN ETHERNET eI/O MODULE
An eI/O module may become no longer visible in the module list in the Ethernet Config utility if the eI/O module has been configured to use a different subnet than the host computer.
In other cases, the eI/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.

Before recovery begins, make certain that the PC and eI/O module are on the same network segment – they should be connected directly using the included Ethernet cable (blue or yellow), through a hub, or through a non-routing switch. The PoE series of eI/O  modules ship with an Ethernet patch cable (blue). The other eI/O models ship with a crossover cable (yellow). If the correct type of cable is used, most PC network cards should support a direct connection with the eI/O module.
Next, select the IP Address of the network card your eI/O module is connected to from the dropdown labeled “Network Interface.”

If IP address of that network card should be in the same subnet with (but not identical to) the IP address that the reset will give the eI/O module. If this is untrue, or the IP address of the network card is within one number of the eI/O modules’s current IP  address, reconfigure the card to another IP address before you proceed. Once the card is reconfigured, click “Cancel” in the reset window and click “Recover Module” again. You can now select the card’s new IP address under “Network Interface”. After the  module is configured, you can restore the network card to its original IP address.

Enter the MAC address found on the label on the bottom of the eI/O enclosure. A MAC address is made up of six pairs of hexadecimal digits separated by dashes (i.e., xx-xx-xx-xx-xx-xx). The label on your device may or may not include the dashes. 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.

Advanced Features
ADVANCED FEATURE CAPABILITY
Modules with version “2” or higher support several Advanced Features. You may determine the version of your SeaIO device using the MODBUS command FUNC_SEAMAX_GET_EXTENDED_INFO (0x66), using the SeaMAX method SM_GetDeviceConfig(),  or by viewing the Module Description in MaxSSD, shown below.

FIRMWARE UPGRADING
In the event that a newer version of the 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 unit must be directly connected to the  programming computer.

The following 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 re-program it locally or send it back to Sealevel  Systems, Inc. for reprogramming.

Exercise caution when performing a firmware upgrade to ensure that the process does not get interrupted until it is completed. 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.

This firmware upgrade will be a file with a name similar to your eI/O model number with an extension of “.hex”. As an example, it you have an eI/O 120 style module, the programming file name would be “120.hex”. Please contact Tech Support to receive the  latest version of the firmware.
The device’s firmware can be upgraded in one of two ways. The preferred method is through is through the MaxSSD Configuration Utility the command prompt. The second is using a command prompt procedure.

UPGRADING FIRMWARE VIA THE MAXSSD CONFIGURATION UTILITY
To upgrade your firmware through MaxSSD, connect to your device normally, and then go to the “Advanced” tab. At this point, you can use the “…” button to browse for the *.hex file you wish to update your device with.

Once the proper file has been selected, click on the “Flash Firmware” button.

At this point, SeaMAX will give you a warning dialog. If you click “OK” then MaxSSD will attempt to flash your device with new firmware. If you click on the “Cancel” button, no changes will be made.

Clicking “OK” will result in IOCU.exe being run in a terminal window. Once the unit has received the download request it will turn on the ACT light. Once the download starts, the ACT light will flash rapidly as data is downloaded. Once the download is complete,  the ACT light will remain on while the device is reprogramming itself. The unit will then reboot itself to reload the new firmware. At this point, the ACT light will turn off, and the terminal window will close. MaxSSD will return you to the Host PC  Configuration tab.

UPGRADING FIRMWARE VIA COMMAND PROMPT PROCEDURE
To execute IOCU.exe from a command prompt, Click on Start, then click Run and type “cmd” (without the quotation marks) and hit ENTER. You will then see a command prompt (i.e. c:\documents and settings\name>). Once you are at the command prompt,  browse to your SeaMAX folder. The default location is “C:\Program Files\Sealevel Systems\SeaMAX\” (or “C:\Program Files (x86)\Sealevel Systems\SeaMAX” on 64-bit systems). Your *.hex file should be saved to this folder as well. If your operating system  requires administrator permissions for this action and you cannot provide them, another folder outside the Program Files folder can be used, but a full path to the file will be required in the following step.
Type

Cd “C:\Program Files\Sealevel Systems\SeaMAX\” and then press Enter
When the command calls for iii.iii.iii.iii you substitute the unit’s IP address. Please do not enter the numbers with a leading zero. Therefore, if your IP address is 192.168.42.11, you will enter 192.168.42.11 and not 192.168.042.011. The command for this is  therefore:
iocu /i=192.168.42.11 /a=247 120.hex
Once the unit has received the download request it will turn on the ACT light. Once the download starts, the ACT light will flash rapidly as data is downloaded. Once the download is complete, the ACT light will remain on while the device is reprogramming itself.  The unit will then reboot itself to reload the new firmware. At this point, the ACT light will turn off.

Connector Pin Outs
eI/O ETHERNET PINOUT
eI/O Ethernet connector is used for both data and power in the PoE series of modules. Both DC on spares (Mode B) and mixed DC and data (Mode A) Power over Ethernet 802.3af-2003 configurations are acceptable for the eI/O. The eI/O PoE series modules  are class 0 power over Ethernet devices.

ETHERNET / POE (CONNECTOR – RJ-45)

This module is not intended to be directly connected to wiring outside a building.

Mounting Options

DIN Rail Mounting
eI/O modules ship ready for mounting on DIN rail. A small, rugged plastic (shown below) is included that naps onto 35mm DIN rail. This offers a clean installation by locating the I/O modules near the industrial control equipment on the DIN rail. Additionally,  3.5mm removable screw terminals allow for an easy and reliable connection method.

Wall/Panel Mounting
As an alternative to DIN rail, the versatile plastic clip includes mounting holes that allow eI/O modules to be mounted to walls, under counters, or inside panels. The plastic clip can be permanently mounted to a surface while still allowing the eI/O module to be  easily removed for service or configuration changes.

Table/Desktop Mounting
eI/O modules are perfect for table or desktop use. The units ship with four rubber feet that help prevent the devices from sliding due tovibration and help protect surfaces from scratches. The smallenclosures take up very little space.
