1. Make sure that the GPS is plugged into the proper DB-9 input. Looking at the back of the
instrument, the GPS should be plugged into the leftmost input port. A null modem adapter should
not be used.
2. Make sure that the GPS has power and has been turned on long enough to start outputting data.
Some units may require a couple minutes to start while others may require much longer.
3. Make sure the GPS output is at 4800 baud, 8 data bits, no parity and 1 stop bit. (note: set parity
to “None”, not “zero”)
4. Make sure the GPS is set to output NMEA-0183 messages that include the GGA and VTG or
RMC string. The GGA string provides the position and fix quality while the VTG or RMC string
provides the speed. Make sure the update rate is set at 1 Hz.
5. If your settings appear correct, but the position still does not appear on the Veris instrument, use
a laptop to monitor the GPS signal to verify its integrity. If the signal appears properly on a
laptop, it should work on the instrument as well.
