Appendix A: Troubleshooting

Table A-1 provides troubleshooting for common problems.

Table A-1: Troubleshooting

Symptom

Possible Solution

Receiver fails to power

•

Check integrity of power cable connectors

•

Check power input voltage (6 to 36 VDC)

•

Check current restrictions imposed by power
source (minimum available should be > 1.0 A)

No data from V104n

•

Check receiver power status to ensure the receiver
is powered (an ammeter can be used for this)

•

Check integrity and connectivity of power and data
cable connections

No GPS lock

•

Verify the V104n has a clear view of the sky

•

Verify the lock status of GPS satellites

No SBAS lock

•

Verify the V104n has a clear view of the sky

•

Verify the lock status of SBAS satellites

Note:

SBAS lock is only possible if you are in an

appropriate SBAS region; currently, there is limited
SBAS availability in the southern hemisphere.

No heading or incorrect
heading value

•

Heading is from primary GPS antenna to secondary
GPS antenna, so the arrow on the underside of the
V104n should be directed to the bow side

•

Monitor the number of satellites and SNR values
for both antennas - at least four satellites should
have strong SNR values
