Appendix A: Troubleshooting

Table A-1 provides troubleshooting for common problems.

Table A-1: Troubleshooting

Symptom Possible Solution

Receiver fails to power • Verify polarity of power leads

• 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 V102 • Check receiver power status to ensure the receiver

is powered (an ammeter can be used for this)

• Verify desired messages are activated (using

PocketMax or $JSHOW in any terminal program)

• Ensure the baud rate of the V102 matches that of

the receiving device

• Check integrity and connectivity of power and data

cable connections

Random data from

V102

• Verify the RTCM or binary messages are not being

output accidentally (send a $JSHOW command)

• Ensure the baud rate of the V102 matches that of

the remote device

• Potentially, the volume of data requested to be

output by the V102 could be higher than the current

baud rate supports (try using 19200 as the baud

rate for all devices or reduce the amount of data

being output)

No GPS lock • Verify the V102 has a clear view of the sky

• Verify the lock status of GPS satellites (this can be

done with PocketMax)
