920i, 820i and 720i WLAN Option Installation
2 Visit our website www.RiceLake.com
2 : WLAN Option Installation
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 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 – Option card is not hot swappable.
The 920i, 820i and 720i do not have a 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.
1. Disconnect power to the indicator and open enclosure according to the indicator’s manual.
2. Carefully align the J1 connector on the bottom of the WLAN option card with an available option slot connector.
3. Press down on the option card board until it is seated into the option slot connector.
4. Use the two screws provided in the option kit to secure the other end of the option card to the threaded standoffs.
5. 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.
6. Connect the RP-SMA side of the antenna cable to the antenna.
7. Connect the u-Fl end of the antenna cable to the Antenna 1 connection on the WiFi module (Figure 2).
Figure 2. Antenna Connection Location
The Antenna 1 connection is located on the centerline of the WiFi module.
8. Tighten the cord grip around the antenna, making sure the end of the antenna has been pushed through to the exterior
of the enclosure. Torque the cord grip nut (inside 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).

3 : Option Jumpers
Refer to Figure 3 and Table 2 for the jumper locations and descriptions for the WLAN Option board.
Figure 3. Jumper Locations on the WLAN Option Board
Jumper Description
JP1 and JP9 RXD / TXD Select Jumpers (RS232 / xPICO WiFi) – These jumpers 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.

4 : Reset Button
The Reset Button performs a reset and reboots the WiFi module.
Figure 4. Reset Button Location
5 : 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.
3. Remove the shorting shunt from the DFLT pins. The WiFi module is now defaulted.
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.
6 : Soft AP (Access Point)
The recommended method to configure the WLAN option card 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.

7 : 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 connected to the WiFi module. The
second port can be configured for use as an RS232 port through the J3 connector.
RS232 J3 Setup Procedure
1. Move both of the JP1 and JP9 jumpers to the RS232 position.
2. Confirm that both of the JP10 and JP11 jumpers are in the OFF position.
3. Route cable to the J3 connector. See Figure 5 and Table 3 for wiring.
4. 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 option is installed into Option Slot 1, it appears as serial ports 5 and 6. Making port 6 the second port.
Figure 5. Serial Port Location
8 : 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 configuration, the first port's Baud, Bits, and Parity
settings must remain at their default settings of 9600 (Baud), 8 (Bits), and None (Parity) in order for the indicator to work with
the WiFi module. Other settings, such as the port's Function, Echo, and Response can be changed as needed.

9 : 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 Card'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 card's Soft AP is available any time the card is powered up.
Soft AP (Access Point) Details
• Name: RLWS_XXXXXX
• Password: PASSWORD
• Configuration Page: https://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.
10 : WiFi Setup
The following procedure is for setting up the WLAN Option’s WiFi network using the WLAN Option’s built-in Web Manager.
1. Power on the indicator and wait for the WiPWR LED to light solid.
Figure 6. WiFi LED Locations
2. 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.
