Note: If you do not connect this pin to the ignition, you MUST connect it to the positive terminal of your power supply or
battery. The device looks for a qualified voltage on this pin as part of the power up sequence. If it doesn’t see it, the
device will not turn on. If you are using a Sierra Wireless AC power adapter, the connection is inside the cable.
