Dual mode with external cellular modem/router
As an alternative to the EXPLORER 540 Cellular Modem you can use an external 3rd
party cellular modem/router connected to the LAN interface.
In the scenario below, an external cellular modem/router is used to provide
connection to a cellular network while the BGAN connection is used for backup. Power
is supplied from a separate battery connected to the DC input of the EXPLORER 540
and to the external cellular modem/router.
• For specifications and pinout for the DC input on the EXPLORER 540, see DC power
input (X4) on page A-4.
• For specifications and pinout for the LAN input on the EXPLORER 540, see LAN
interface (X1 or X2) on page A-2.
• For installation instructions for the EXPLORER 540 terminal, see the supplied
EXPLORER 540 Installation guide. Note that you must use a fused or current-limiting
DC power supply (battery).
• For installation instructions for the external modem/router, see the documentation
for the modem/router.
