Connecting Power
The GPS-205 has an input voltage range of 9
– 30 V DC. (See Table 2 and Table 3). The power and
ignition pins can support 9 – 30 V DC 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:
