What to do if Hemisphere GPS V102 G Marine GPS System receiver fails to power?
If your Hemisphere GPS Marine GPS System receiver isn't powering up, check the polarity of the power leads, inspect the power cable connectors for damage, ensure the power input voltage is within the range of 6 to 36 VDC, and verify that the power source provides a minimum available current of > 1.0 A.
What to do if Hemisphere GPS Marine GPS System has no GPS lock?
If your Hemisphere GPS Marine GPS System isn't locking onto GPS satellites, make sure the V102 has a clear view of the sky. You can also verify the lock status of GPS satellites using PocketMax.
What to do if Hemisphere GPS V102 G has no data from V102?
If you are not receiving data from the V102 unit of your Hemisphere GPS Marine GPS System, check the receiver's power status using an ammeter to ensure it is powered on. Verify that the desired messages are activated using PocketMax or the $JSHOW command in a terminal program. Ensure the baud rate of the V102 matches the receiving device, and inspect the power and data cable connections for integrity and connectivity.
What to do if Hemisphere GPS V102 G has no SBAS lock?
If your Hemisphere GPS Marine GPS System is not locking onto SBAS satellites, ensure the V102 has a clear view of the sky. Verify the lock status of SBAS satellites using PocketMax, monitoring the BER value. Set the SBAS mode to automatic using the $JWAASPRN,AUTO command. Note that SBAS lock is only possible within an appropriate SBAS region; availability is currently limited in the southern hemisphere.
What to do if Hemisphere GPS V102 G Marine GPS System has random data from V102?
If your Hemisphere GPS Marine GPS System is showing random data from the V102, verify that RTCM or binary messages are not being output accidentally by sending a $JSHOW command. Also, ensure the baud rate of the V102 matches that of the remote device. The volume of data requested from the V102 might be too high for the current baud rate; try using 19200 as the baud rate for all devices or reduce the amount of data being output.
