Airlink101 LX60 Hardware User's Manual page 21

If desired, you can configure a delay between the time the vehicle's ignition shuts off, and
the time the router 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.

Vehicle Installation: Option 2
The main difference between this installation and vehicle installation option 1 is that you
can configure a timer to turn the router 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
router turning on and off, the router alternates between on and standby mode.

Pin 1 (Power) —Use the red wire in the DC cable to connect Pin 1 to the power
source. Include a 4 A, fast blow fuse, recommended to have no more than ±10% de-
rating over the operating temperature range, in the input power line. Sierra Wireless
recommends using a continuous (unswitched) DC power source. Connect the power
through the vehicle's fuse box.
Pin 2 (Ground)—Use the black wire in the DC cable to connect Pin 2 to ground. See
also Step 2—Mount and Ground the LX60 Chassis
Pin 3 (On/Off) —Sierra Wireless recommends always using the On/Off wire (Pin 3) to
turn the router off. It should not be turned off by disconnecting the power.
