2.2.6 Navigation Sensors

J9 (DB-37 Female on backpanel) provides four RS-232 ports to connect the optional fluxgate compass and up to 3 GPS receivers. Route the cable away from electrically noisy devices (motors, air conditioners, etc.) to avoid unnecessary problems.

Original RC3000s

A DB-37 to two DB-9 Female cable is supplied for connecting to the GPS receiver and the Fluxgate compass. Pinouts for the third and fourth serial ports available from J9 are not shown as these ports are currently not used.

The J13 DB-9 (Female on backpanel) connector (below the J7 drive connector) provides a “GPS loopout” interface. Another device (such as a TDMA modem) may listen to the output of the GPS receiver in order to obtain latitude, longitude, height, time, etc. The pinout of J13 is identical to the GPS DB-9 connector shown above.

Second Generation RC3000s

Rather than having the DB-37 connector, there is an individual DB-9 Female (J13) for the GPS interface and an individual DB-9 Female (J9) for the compass. The pinouts of these connectors will be as shown above for the DB9s.

NOTE: the GPS loopout connector is designated J15 (DB9 Female on backpanel) on second generation RC3000s.
