6.1 Cellular Modem Board
The LTE (United States) or GSM (outside the United States) cellular modem is an optional accessory that is installed on the
processor board on the two 12-pin sockets.

A - U.FL antenna connection
The U.FL connector should be to the left, with the antenna cable going to the left antenna U.FL connector. The SIM card
slides into the socket on the back of this board.
6.2 Cellular Power Requirements
If the incoming voltage drops below 11.2 V dc, the cellular modem does not turn on and will not turn on until the voltage is
above 11.8 V dc. A text file (CmVMon.txt) on the internal micro SD card saves the periodic sampling of the incoming voltage.
If cellular operation stops because of voltage, it is logged in this file.
6.3 Using the DXM Cellular Modem
The DXM cellular modem provides a remote network connectivity solution for the DXM.
To use the cellular modem:
1. Verify the cellular modem is installed and the correct antenna is connected to the cellular antenna port.
2. Activate the cellular service.
3. Configure the DXM to use the cellular network as the network interface.
