PN 206461 Rev B

The indicator automatically recognizes all installed option cards when the unit is powered on. No hardware-specific configuration is required to identify an installed option card to the system. The WLAN Option appears as a dual serial card, however, only the first serial port can be connected to the WiFi module.
For Example: If an option is installed into Option Slot 1, it appears as serial ports 5 and 6, however, only port 5 is available for use with the WiFi module. The second port, port 6 in this example, can be configured for use as an RS232 port through the J3 connector (see Available Serial Connection on page 5).

• Electric Shock Hazard – The option card is not hot-swappable.

• The 920i, 820i, and 720i do not have an on/off switch. Always disconnect power before opening an enclosure.
  A grounding wrist strap must be worn to protect components from electrostatic discharge (ESD) when working inside an enclosure.

• Use this procedure to install the WLAN Option card and antenna.

• Disconnect power to the indicator and open the enclosure according to the indicator’s manual.

• Carefully align the J1 connector, on the reserve side of the WLAN Option, with an available option slot connector.

• Press down on the option cardboard until it is seated into the option slot connector.

• Use the two screws provided in the option kit to secure the other end of the option card to the threaded standoffs.

• Slide the antenna through the largest available cord grip.

• The antenna joint should be exposed and positioned to follow the travel of the indicator’s tilt direction.

• It is recommended to expose as much of the antenna as possible to help with signal strength.

• Connect the RP-SMA side of the antenna cable to the antenna.

• Connect the u-Fl end of the antenna cable to the Antenna 1 connection on the WiFi module

• The Antenna 1 connection is located on the centerline of the WiFi module.

• Tighten the cord grip around the antenna and torque the cord grip nut (inside the enclosure) to 33 in-lb (3.7 N-m) and torque the cord grip dome nut (around cable) to 22 in-lb (2.5 N-m)

Option Jumpers

Refer to Figure 3 and Table 2 for the jumper locations and descriptions for the WLAN Option board.

select if RS232 is available through the second port of the option board. For most applications both the JP1 and JP9 jumpers should be in the xPICO WIFI position.

NOTE: The second port is NOT actually connected to the WiFi module in the xPICO WIFI position, it is simply not used.

When the jumpers are in the RS232 position, the second port on the board is routed to the TXD / RXD connection on the J3 connector to be used as a serial port. See Available Serial Connection on page 5 for more information.

NOTE: The jumpers must always be set in the same position. If JP1 and JP9 are in the RS232 position, then JP10 and JP11 jumpers must be in the OFF position. The JP1 and JP9 must NEVER be in the RS232 position at the same time JP10 and JP11 are in the ON position.

JP2| Power Jumper (BUS / AUX) – Defines where option board gets power from. If installed in an indicator option slot, the jumper must be in the BUS position to pull power from the indicator. In the rare situation where the board is mounted externally (not on the “Bus”), then the jumper needs to be in the AUX position with 6-12 VDC applied to the AUX V+ and GND Pins of the J3 connector.
JP3| Soft AP Jumper (ON / OFF) – This jumper can be used to Enable or Disable the Soft AP (Access Point) feature of the WiFi Module. See Soft AP (Access Point) on page 4 for more details on the function of the Soft AP.

NOTE: This is an advanced feature and the jumper is not enabled by default. Contact Rice Lake if there is a need to disable the Soft AP.

JP4| Default Jumper – This jumper connects to the Default pin of the WiFi module. This jumper can reset the module to factory OEM defaults if the user cannot do so through the Web Manager. This jumper must remain OFF for normal operation. See WiFi Module Default Procedure on page 4 to reset the module to factory defaults.
JP10 and JP11| RXD / TXD Config Jumpers (ON / OFF) – These jumpers are used to select the connection to the WiFi module.

–  For normal operation: Set both JP10 and JP11 to the OFF position. This connects the WiFi module to the first port on the card.

–  For alternative operation: Set both JP10 and JP11 to the ON position. This connects the WiFi module to the J3 RS232 port. This can be used to route another serial port to the WiFi connection to allow serial data communications to a port other than the two available though the bus. This connection scheme can also be used to configure the WiFi module, but this is a more advanced feature not discussed in this document. Refer to the xPico 200 Series User Guide at www.lantronix.com for more information.

NOTE: The jumpers must always be set in the same position. If JP1 and JP9 are in the RS232 position, then JP10 and JP11 jumpers must be in the OFF position. The JP1 and JP9 must NEVER be in the RS232 position at the same time JP10 and JP11 are in the ON position.

Reset Button

The Reset Button performs a reset and reboots the WiFi module.

WiFi Module Default Procedure

The JP4 DFLT jumper can be used to reset the configuration of the WiFi module to factory OEM defaults.

1. With the board up and running, apply a shorting shunt to the DFLT pins for at least six seconds. See Option Jumpers on page 3 for the jumper’s location.
2. The WiPWR LED starts to flash. See WiFi Setup on page 6 for the LED’s location.

Remove the shorting shunt from the DFLT pins. The WiFi module now defaults.

Defaulting the WiFi module does not reset the WiFi connections, but enables a disabled Soft AP to allow access to the configuration. This jumper, along with the reset switch, can also allow the module to boot into command line mode. This is an advanced function not discussed in this document. Refer to the xPico 200 Series User Guide at www.lantronix.com for more information.

Soft AP (Access Point)

The recommended method to configure the WLAN Option to connect to a location’s network is to use the built-in Web Manager. The preferred method to access the built-in Web Manager, before the WLAN Option is on the location’s network, is to use the built-in Soft AP and do the configuration needed to connect to the network (see WiFi Setup on page 6).

The card can be configured using RS232 through the J3 connector, but by default, the module is not set up to do this and would need to be booted into the command line mode to do so. This is an advanced function not discussed in this document. Refer to the xPico 200 Series User Guide at www.lantronix.com for more information.

Soft AP as the WLAN Connection

In applications that don’t have a local network to connect to or if the network is not in range, the Soft AP connection can also be used to talk to an indicator using the WLAN Option by connecting to IP 192.168.0.1, port 10001.

Available Serial Connection

A previous version of the WLAN Option used the serial connection to configure the WiFi module to connect to a network. Even though this is still possible with this xPico-based WLAN Option, the preferred configuration method is now through the WiFi module’s built-in Web Manager.

In addition to network configuration, the serial port can also be used to talk through the WiFi module, but both are advanced features not discussed in this document. Refer to the xPico 200 Series User Guide at www.lantronix.com for more information.

The WLAN Option appears as a dual serial card, with the first serial port being used to connect to the WiFi module. The second port can be configured for use as an RS232 port through the J3 connector.
RS232 J3 Setup Procedure

• Move both the JP1 and JP9 jumpers to the RS232 position.
• Confirm that both of the JP10 and JP11 jumpers are in the OFF position.
• Route cable to the J3 connector. See Figure 5 and Table 3 for wiring.
• In the indicator, configure the WLAN Option’s second (higher numbered) serial port as needed to communicate with the external device connected to the J3 connector.

For Example: If an option is installed into Option Slot 1, it appears as serial ports 5 and 6. Making port 6 the second port.

NOTE: Aux V+ is used to provide power to the board when JP2 is in
the AUB position. It is not a power source, and typically not used.

Indicator Configuration

The WLAN Option appears as a dual serial card. When the WLAN Option is installed, additional serial ports will become available in the indicator configuration, depending on the slot the card is installed in.

•  If in slot 1 – ports 5 and 6 will be available
•  If in slot 2 – ports 7 and 8 will be available
• Pattern continues if additional slots are available

The first (lower numbered) port connects to the WiFi module. In the indicator’s configuration, the first port’s Baud Rate, Bits, and Parity settings must match the WiFi module’s settings. The WiFi module’s default settings are 9600 (Baud Rate), 8 (Data Bits), and None (Parity). Other indicator settings, such as the port’s Function, Echo, and Response can be changed as needed.
See Serial Port Settings on page 9 to change the WiFi module’s default settings using the Web Manager.

Wireless Configuration

Configuration of the wireless settings is done through the WLAN Option’s built-in Web Manager. If already connected to a network, a web browser on that network can connect to the Web Manager by simply navigating to the WLAN Option’s IP Address.
If not already connected to a network, or configuration through the network is not desired/available, then the Web Manager may be accessed through the WLAN Option’s Soft AP. By default, the option’s Soft AP is available any time the card is powered up. Soft AP (Access Point) Details

• Name: RLWS_XXXXXX
• Password: PASSWORD
• Configuration Page: http://192.168.0.1

The Soft AP only shows up as a 5 GHz network. The connecting device must be capable of using the 5 GHz band to connect to the Soft AP.

WiFi Setup

The following procedure is for setting up the WLAN Option’s WiFi network using the WLAN Option’s built-in Web Manager.

Power on the indicator and wait for the WiPWR LED to light solid. See Figure 6 for the LED’s location.

Scan for available WiFi networks using a computer or phone and connect to the Soft AP. It might take a few attempts before the Soft AP appears on the computer or phone.

• Soft AP Name: RLWS_XXXXXX
• Soft AP Password: PASSWORD

It is recommended to change default passwords to limit access and for security.

The X’s in the name represent the last 6 digits of the WiFi MAC address. The serial number on the WiFi module’s label is almost the same, other than the last digit being one number/character less than the WiFi MAC address.
For example, if the module’s serial number is “0080A3E8C27A”, then the SSID would be “RLWS_E8C27B”. The MAC address is a Hexadecimal value, so the letter A follows the number 9, and this continues to F before incrementing the next most significant digit and returning to 0.

Once connected to the Soft AP, use a web browser and enter 192.168.0.1 as the URL address, and press Enter. Once connected to a network, a web browser on that network can connect to the Web Manager by simply navigating to the WLAN Option’s IP Address (available on the Status page of the Web Manager).

• Enter the default login credentials for the Web Manager.
• Username: admin
• Password: PASSWORD

It is recommended to change default passwords to limit access and for security.

Press Sign in. The Web Manager loads in the browser and the Status page appears.

A list of wireless networks appears Click the network name intended to connect to the WLAN Option’s WiFi network. If the necessary network does not show up, just click the Scan button again. It may take a few tries to show the network. If the network is hidden, enter the network name in the box provided.

The Web Manager provides notes and information related to the current page in the far right column. Descriptions for options and settings are also provided when hovering over the item in question.

The wireless network information page appears. Enter the network password (if applicable). Contact the location’s IT, administrator, to obtain network credentials as needed based on the security that is in place.

Click Submit to apply and save the settings. A message displays at the top of the page to show if the new network’s Profile is saved successfully. It does not necessarily mean it is connected to the network.

The Apply button only applies the settings for the current session but does NOT save them. 10. To verify that the WLAN Option is connected to the location’s network, click Status near the top of the left nav.

11. The Status page shows all of the network connections on the device under Network Settings.

If Connected: Interface wlan0 is listed with Connection State showing Connected and the IP Address populated. The WLACT LED on the card also lights when connected to a network (Figure 6 on page 6).
The “/24” at the end of the IP Address indicates the number of bits set for the network subnet mask and is not part of the IP Address itself. There are 32 bits in a subnet mask and “/24” indicates the subnet mask is 255.255.255.0.If Not Connected: Click WLAN Profiles at the bottom of the left nav to change the network settings and try again.

Connecting to the WiFi module’s server with a remote client is now possible. By default, the WiFi module is configured as an RS232 to WLAN tunnel for serial communication.

In the indicator’s configuration, the port’s Baud Rate, Bits, and Parity settings must match the WiFi module’s settings. The WiFi module’s default settings are 9600 (Baud Rate), 8 (Data Bits), and None (Parity). Other indicator settings, such as the port’s Function, Echo, and Response can be changed as needed. See Serial Port Settings to change the WiFi module’s default settings using the Web Manager.

Using a Terminal Emulation program, such as Putty, as a remote client connection to the WiFi module’s server over Telnet is possible using the IP Address that was noted in Step 11 on page 8 and the Local Port number, which by default is 10001.

• Putty Example
  If the card’s IP address changes and there is no longer access to the card through the location’s wireless network, connect to the Soft AP and use the Web Manager to learn the new IP Address.
  If the Web Manager cannot be reached through the location’s wireless network or the Soft AP, the card needs to default. See WiFi Module Default Procedure on page 4.
