GPS Connection

Cable Connections

A GPS/DGPS cable (item # 2950CV5) is required to
connect the pH110 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 generally 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 signal, check that it has the following set-
tings:

Data bits: 8

Stop bits: 1

Baud rate: 4800 bps

Parity: None

Timing: 1 second
