Connectivity Modules
EMG provides two connectivity slots for user replaceable connectivity modules on the back of the
unit.
Note:
When installing the connectivity modules, they can be populated or swapped in
any order. One or both of the slots can be empty. The connectivity modules must only be
installed on the back of the unit, never in the I/O slots on the front.
LTE Cellular Modem
One LTE/4G cellular modem may be installed in either connectivity slot. The LTE cellular modem
may be configured to function as the failover interface with Eth1 as the primary link.
The LTE cellular modem module supports one main antenna, one AUX antenna, and one GPS
antenna for geolocation. (The geolocation function is not active in the current release).
The LTE cellular modem module supports one external SIM card, provided by the user. The SIM
card slot is located on the inside of the cellular modem module, as shown in
. To install
the SIM card, power off the EMG unit, unscrew the module faceplate and remove it from the EMG
unit. Insert the SIM card into the slot and replace the cellular modem module in the EMG unit.
