Navigation Data Ports for GPS Comm
(These ports are completely independent of the EDM-760/790 serial data output port.)
Navigation Data (output of GPS; input to EDM-760/790)
Compatible with RS-232, TTL, RS-423, RS-422 SDA.
Serial data format 8 data, 1 start, no parity. Baud rates: 1,200, 4,800, or
9,600 depending on the GPS data output format. The EDM-760/790
automatically detects the GPS data output format and is independent of the
GPS-C setting.
Fuel Data (input to GPS; output of EDM-760/790)
Serial data format 8 data, 1 start, no parity. Baud rate: 9,600.
Output format is determined by the GPS-C setting, but may be over-ridden
by the GPS navigation format: If the EDM-760/790 senses Northstar or
NMEA-183 navigation data input, there will be no fuel data output.
