RC3000 Antenna Controller Appendix HGPS Hemisphere GPS Compass

HGPS-9

4.0 Troubleshooting

NO COMMUNICATION

The GPS engine needs to be programmed to the correct settings to work with the RC3000 controller.

The engine will come from RCI programmed to the correct settings. This programming is accomplished

via the Window's program "PocketMaxPC version 2.0" supplied by Hemisphere.

If the GPS engine must be reprogrammed the following tables are included to document the desired

settings. Note that the PocketMaxPC software will be looking for a "Hemisphere Vector" device at 4800

baud.
