Fuel Data (input to GPS; output of EDM)
RS-232. 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 senses Northstar
or NMEA-183 navigation data input, there will be no fuel data
output.
