WLAN Option Setup

The xPico-based WLAN Option is a way to add a WiFi interface to several RLWS products by connecting to the 20-pin communications option slot of the product’s CPU board. Depending on the product, the option card either takes an existing RS232 communications port or provides access to an addition port.

The option card accesses up to two different communications ports available through the communications option slot connection.
The ports and capabilities vary by product. See Table 2 for selecting ports and proper voltage for the WLAN Option.

Only one communications port can be connected to the WiFi module at a time. In Table 2 and as marked on the product’s CPU board, the two ports are labeled A and B. In addition, there is a RS232 communications port on the WLAN Option that can either be connected directly to Port A or the WiFi module. This allows for a third way to connect to the WiFi module.

• CPU Port2/OPT Jumper must be ON
• CPU JP3 must be in the COM-OPT Position

NOTE: If a port is used on this option card, it is no longer available on the CPU board and nothing should be connected to it.

In the product’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 product 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. 

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.

The card can be configured using RS232 through the J2 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 atwww.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.

Option Jumpers and Switches

Refer to Figure 2 and Table 3 for the jumper locations and descriptions, and Figure 2 and Table 4 for the switch locations and descriptions for the WLAN Option board.

to the board. Please refer to Table 2 for the correct position based on the product.
RST| Reset Jumper – Shorting this jumper pulls the card into reset. Used to perform a soft power-up reset on the board (not typical).
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) 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 to reset the module to factory defaults.

Table 3. Jumper Descriptions

Port B connection. It is important that this be correct before applying power. Please refer to Table 2 for the required setting based on the product.
SW4| The Data path select switch. This switch routes the data from Ports A, B, the Wifi module, and J2 to various locations.

•  A and B route the data to/from the WiFi module to Ports A and B respectively.
• J2 routes the data to/from the WiFi module to the J2 RS232 connection.
• A-J2 skips the WiFi module all together and routes the J2 RS232 data directly to Port A.

NOTE: Only one switch can be ON at a time with one exception, selection A-J2 and B. In the case of using Both A and B ports, both A-J2 and B can be ON at the same time to allow the Port A data to go to J2 for an additional Serial Port, while the data from Port B is routed to the WiFi module. See Available Serial Connection .

WLAN Option Installation

The WLAN Option is automatically recognized when the product is powered on. No hardware-specific configuration is required to identify an installed option card to the system. The option is installed on the 20-pin Communications Option Slot.

Electric Shock Hazard – Option card is not hot swappable. 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

Please refer to Table 2  for the correct positions of the switches and jumpers on the WLAN Option board. This is important to do before powering up the product to prevent possible damage to the option card.

1. Disconnect power to the product and open enclosure according to the product’s manual.
2. Install the two support posts provided in the option kit into the two holes of the WLAN Option card. The posts should protrude from the bottom of the card, opposite the side with the switches.
3. Carefully align the J1 connector, on the reverse side of the WLAN Option, with the 20-pin Communications Option Slot on the product’s CPU board ( Table 5 ). Ensure that two posts are also aligned with the corresponding holes on the product’s CPU board.

4. Press down on the option card board until it is seated into the product’s CPU board connector.

5. Slide the antenna through the largest available cord grip.
   In wash down environments, the antenna joint should not be exposed to the environment to avoid product getting trapped in the joint. In non-wash down applications, the joint should be exposed and positioned to follow the travel of the product’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 3 ).
   
   __ The Antenna 1 connection is located on the centerline of the WiFi module

8. Tighten the cord grip around the antenna and 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).

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 and Switches for the jumper’s location.
2. The WiPWR LED starts to flash. See WiFi Setup 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. The DFLT jumper, along with the reset (RST) jumper, 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 atwww.lantronix.com for more information.

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. Using a serial connection for network configuration is an advanced feature not discussed in this document. Refer to the xPico 200 Series User Guide at www.lantronix.com for more information.

RS232 J2 Setup Procedure
Follow this procedure to allow for the use of both available ports (A and B) of the WLAN Option, with Port A data going to the J2 as an additional serial port, while data from Port B is routed to the WiFi module.

1. Move both the A-J2 and B switches to the ON position. See Figure 4 for the location of the SW4 switches.
   __Normally only one switch can be ON at a time with this being the one exception.

2. Confirm that both the A and J2 switches are in the OFF position.

3. Route cable to the J2 connector. See Figure 4 and Table 6 for wiring.

4. In the indicator, configure the WLAN Option’s serial port as needed to communicate with the external device connected to the J2 connector. Refer to Table 2   for the port use depending on the product.

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.

1. Power on the indicator and wait for the WiPWR LED to light solid. See Figure 5 for the LED’s location.
   

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.

3. 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).
