Troubleshooting Chapter 7
SUPERSTAR II User Manual Rev 3 43
• Verify DGPS base station is actually transmitting DGPS corrections and base data is being
received by the SUPERSTAR II.
4. If you are not receiving expected messages from the SUPERSTAR II:
• Verify transmit message settings (i.e. receiver's output configuration or requested message).
• Verify hardware and software part numbers are as per expected configuration.
• Restore default settings by sending an Erase NVM command (Message ID# 99, Erase NVM)
to the SUPERSTAR II
• Read the Reference Manual - refer to the L1 GPS Firmware Reference Manual describing
message contents.
For the problems above you may be able to isolate the suspected unit in your application:
• Substitute another SUPERSTAR II.
• Substitute another host hardware.
• Substitute another RF source (i.e. antenna, cable).
• Substitute another interconnect harness.
• Substitute alternate power source or isolate main power source from auxiliary power source
for SUPERSTAR II.
• Make intermittent problems more repeatable (i.e. by raising operating temperature, varying
power supply source, re-orienting hardware placement). Be sure to note what makes the
problem worse / lessens the problem.
Having gone through the steps in this chapter and, if possible, the substitutions above, contact Customer
Service (see Page 9).
• Describe your problem, be sure to include observations, symptoms and environmental
conditions for your application.
• Please supplement your problem / event descriptions with associated log files.
• Give hardware part number and software part numbers (including installed configurations).
• Customer support staff will give you instructions if the unit needs to be returned to the
factory.
