Navigation Data Formats
Output of GPS; input to EDM. The EDM automatically configures itself for
one of three industry standard data formats:
“Output sentence type 1” Required sentences are: A, B, C,
D, E, I and L first character identifier byte. Sentence
terminator may be either <CR><LF> or <CR> alone.
Navigation Data Ports for GPS Comm
(These ports are independent of the EDM serial data output port.)
Navigation Data (output from GPS; input to EDM)
Compatible with RS-232, TTL, RS-423, RS-422 SDA.
Serial format: 8 data, 1 start, no parity. Baud 1200, 4800, or 9600,
depending on the GPS data output format. The EDM automatically
detects the GPS data output format and is independent of the GPS-C
setting.
Fuel Data (input to GPS; output from EDM)
RS-232 Serial format: 8 data, 1 start, no parity. Baud 9600. 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.
