Recommended Vehicle Installation
For vehicle installations, Sierra Wireless recommends connecting the white Ignition Sense
wire to the vehicle's ignition switch, as shown in the following illustration.
Figure 3-6: Recommended Vehicle Installation
The recommended vehicle installation allows the gateway to operate with the vehicle.
When the vehicle ignition is off, the gateway is off. If desired, you can configure a delay
between the time the vehicle's ignition shuts off, and the time the gateway shuts down. A
delayed shutdown is especially useful if you want to maintain a network connection while
the vehicle's engine is shut off for short periods, such as in a delivery vehicle.

Alternate Vehicle Installation
The main difference between this installation and the standard vehicle installation is that
you can configure a timer to turn the gateway on at set intervals for a configured length of
time; for example 20 minutes once every 24 hours when the ignition is off. Also, instead of
the gateway turning on and off, the gateway alternates between on and standby mode.
