If you wish to use the Standby Ignition Sense (SISE) low-power timer feature of
your AirLink GX400, the white wire of the three-wire DC power cable should be
used to connect to your ignition. When SISE is enabled in the device and the
ignition sense connector is wired to your vehicle, the ignition sense will provide a
link to the device to enable it to enter a low-power, standby mode when your
vehicle is turned off and power up more quickly when the ignition is started.

Connecting to a Computer or Other
Device
The AirLink GX400 can be connected to the computer through an Ethernet,
serial, or USB connection.
Ethernet
The Ethernet port is a standard RJ-45 connector; two LEDs indicate link and
activity. The left LED blinks yellow during activity, and the right LED is Green for
100 Mbps and Orange for 10 Mbps. The Ethernet port of the AirLink GX400 can
be connected directly to a computer or other Ethernet device with either a cross-
over cable or a straight-through cable. The Ethernet port on the AirLink GX400 is
auto-sensing, and it will auto-detect the speed of the connecting device for
100baseTX or 10baseT.
