3.4 Connecting Power

The GPS-208 has an input voltage range of 9-16 VDC. The power and ignition pins can support 9-16 VDC input voltage.

The user has an option to connect these wires depending on the desired functionality. Described below are the desired

functionality and their associated wire connecting procedure:

Power to the GPS-208 can be supplied in three different methods, depending upon the application.

long as the battery lasts. If equipped with the optional backup battery, the GPS-208 will remain on until its

internal lithium-ion battery is depleted (approximately 1 hour).

– both external and internal).
