After mounting the GPS 17 in the desired location, connect
the wiring. Connect the GPS 17’s Port 1 Data In, Data Out,
Remote On/Off, and Ground (Return) lines to your NMEA
device or PC. Port 2 is used for RTCM input only.
For reliable communication, it is essential that the GPS
17 and the receiving device share the same ground. This
ground connection acts as the (signal) Return line. Wire
the unit to its own circuit to avoid interference from other
electronics.
You need a DB-9 or DB-25 serial connector (normally
female) if you are connecting the GPS 17 to a PC. Check
with a PC or electronics supplier for these items.
