Rice Lake CLS-420/420Plus WLAN - Manual (Page 3)

5. Route the power cable, which is already attached to the option card, to the power supply.
6. Attach the orange connector with only two wires to the CPU board J7.
7. Attach the other orange connector (with four wires), to the 4-pin connector on the power supply.
8. Re-install the plastic cover on the power supply, if applicable.
Note
Important
Note
If this is a CLS-420 installation, strip about a 1/4" of insulation from the red and black wires that were cut
earlier.
Attach the red wire to PWOUT connection of J6 on the option card and the black wire to the GND connection
next to the red wire. This will provide power to the CLS junction box.
9. Attach the free end of the red wire coming from the option card to Pin 4 (+5V) of J6, using the 4-position
connector included in the parts kit that was supplied with the indicator. Verify PWR jumper on the option
board is in the REM position.
10. Decide which of the two 420 communication ports to attach to the WLAN option. If using the EDP port
(not available on the CLS-420), then connect the white, blue and green wires from the option card to pins 1,
2, and 3 (TxD, RxD, and GnD), respectively on J3. If using the PRN, or printer port, connect like above
except to J4.
Optionally, with the addition of three additional wires (not provided) connected to J1 (Port 1) of the WLAN
option, both the EDP and PRN ports can be connected to the WLAN option board. Do not make this
connection at this time as Port 1 is needed to perform the initial configuration of the option card.
For CLS-420 installations, if the 420 includes a 802.15 wireless load cell kit mounted to the rear of the
enclosure cover, to comply with FCC regulations, the antenna must be placed as far away as possible from the
802.15 wireless load cell kit module. Ensure the antenna is installed in the cord grip closest to the setup switch
access screw.

Initial Configuration
Initial configuration must be performed using an RS-232 connection to a PC, and a terminal program, such as
Hyperterminal. After getting the option card to communicate with the network, Internet Explorer or DeviceInstaller
can be used for a more intuitive, graphical method of configuration to set the remainder of the card’s settings.
Note
The configuration information should be all that is needed to establish a simple connection to most common
wireless networks. However, the MatchPort Device Server is powerful, and there are many settings not
covered in this manual. For more detailed information regarding all the card’s settings and configuration
methods, please refer to the full MatchPort or WiPort

1. Connect a 3-wire RS-232 cable from the PC to J1 (Port 1) of the option card (shown in Figure 4). If using
a DB-9 connection on the PC, PC pin 2 will go to TX, pin 3 will go to RX, and pin 5 will go to GND.
2. Apply power to the 420 and turn it on. Verify the +3.3V LED lights on the WLAN option board. On the
PC, start the terminal program and set it for 9600 baud, 8 data bits, and no parity.
