PWR/DATA
Lowrance 10 pin PWR/DATA connector at the device.
The Lowrance GlobalMap 7000C is a colour chartplotter/GPS unit that exposes three proprietary connectors on its rear panel. The 10-pin PWR/DATA connector carries 13.5 VDC main power, ground, two COM-port data lines, and speaker output; the 4-pin GPS connector links to an external GPS antenna; and the 7-pin sonar transducer connector (not used on the GM-7000 itself) supports transducer, temperature, and speed signals. Only the pins listed in each table are covered here.
