Note: You can use a voltmeter to get the voltage readings on the green connector plugged into the touchscreen. You should be getting 12+ volts.

2. Confirm there is a SIM card in the SIM slot

3. Make sure the link light is on and solid blue 

Note: The blue link light is there to confirm that the SIM card is connected to the network. If you are not seeing the light, try rebooting your unit and waiting 15 minutes. If it still doesn't show up, try swapping the SIM card or the modem.

4. Check the DIV & MAIN wires going from the modem to the circuit board of the touch screen

7. Log into the touch screen, go to Toggle – Parameters – Comm. Parameters, and confirm that there is an IP address

Note: Unlike the WR-21 & 31 modems, the IP on the screen will be the ACTUAL IP of the modem, not the internal IP of the touchscreen
