Sierra Wireless recommends using the Ignition Sense wire to turn the router
off. It should not be turned off by disconnecting the power.
Note: If you do not connect pin 3 to the ignition, you MUST connect it to the
positive terminal of your power supply or battery. If you are using a Sierra
Wireless AC adapter, the connection is inside the cable.
For installations where the router is turned on/off, use the white wire in the
DC cable connected to Pin 3 to:
•
Turn the router on/off with the vehicle ignition
Note: To turn the router on/off with the vehicle ignition, Sierra Wireless
strongly recommends using an unswitched VCC on Pin 1 (Red, Power wire on
DC cable) with Pin 3 (White, Ignition sense wire on DC cable) connected to
the ignition.
•
Turn the router on/off with a low voltage disconnect device
Note: For solar applications, if you want the router to turn off when the
voltage drops below a defined level, connect Pin 3 to an external low
voltage disconnect.
