5. Cellular Modem Boards
5.1. Cellular Modem Board for LTE
The 4G LTE cellular modem is an optional accessory that is installed on the two 12-pin sockets.
Plug the cellular modem into the right socket (when viewing the internal PCB with the connectors at the bottom). The SIM card slides into the
socket on the back of this board.
5.2. 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.
5.3. Using the DXM Cellular Modem
The DXM cellular modem provides a remote network connectivity solution for the DXM1200.
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 DXM1200 to use the cellular network as the network interface.
5.3.1. Activating a Cellular Modem
Follow these basic steps, as detailed in this document, to activate the cellular capabilities of your DXM Controller.
1)
Purchase a cellular modem kit from Banner Engineering Corp.
2)
Install the cellular modem, connect the antenna cable, and connect the cellular antenna.
3)
Activate a cellular plan to the SIM card, then insert the SIM card into the cellular modem.
4)
Configure the DXM to use the cellular modem.
