Connecting the SC900 meter to a GPS unit
Cable Connections
A GPS/DGPS cable (item # 2950CV5) is required to con-
nect the SC900 meter to a GPS unit. This cable has a 9-
pin male connection and a stereo pin that connects to the
meter’s data port. You will also need a cable that allows
the GPS unit to connect to a 9-pin male serial port. If this
cable doesn’t come standard with your GPS unit, it should
be available from the manufacturer. This cable is gener-
ally used to upload information from a computer to the
GPS unit. These components should be connected as
shown in the figure below.
GPS Setting
Your GPS unit must be set for NMEA 0183 input/output
messages. If the meter has trouble receiving the GPS sig-
nal, check that it has the following settings:
Data bits: 8 Stop bits: 1
Baud rate: 4800 bps Parity: None
