How Do I Wire The Sierra Wireless Airlink GX400 Or GX440 To DC Power


If the Airlink GX400/GX440 is used in a vehicle or battery-powered application, the red wire should be connected to battery power and the black wire to ground. The white low-power timer enable wire must be connected to either unswitched or switched power for the GX400/GX440.

PLEASE NOTE: If the white lower-power wire is not used, it must be tied into the red wire. Otherwise, the device will not power on.
