Establishing connections

Operating the MP modem requires some knowledge of both the MP modem hardware and the 3G Watcher software. This chapter describes the basics of each.

Turning the MP modem on and off

If the MP modem is installed in a vehicle, the way in which the MP modem is wired determines how it is powered on and off. In most cases the power supply for the MP modem is the vehicleʹs electrical system and the MP modem is powered on and off in one of these ways:

Engine on. The MP modem is powered only when the ignition is on. (The MP modem is only on when the engine is on.)

—or—

Accessory on. The MP modem is powered when the ignition is switched to ʺAccessoriesʺ. (This allows the MP modem to be powered when the engine is off.)

—or—

Separately switched. The MP modem is connected to a separate on/off switch so that it can be turned on and off independently of the engine and vehicle accessories.

Rather than cutting power to the MP modem, the ignition key or power switch allows the MP modem to perform a controlled shutdown sequence that avoids data loss. (You can also set the MP modem to wait up to 240 minutes after the power switch has been turned off before it shuts down.)
