Navigation Data Formats
Output of GPS; input to EDM. The EDM automatically configures
itself for one of three industry standard data formats:
Format Baud
NMEA-183
(Marine Nav
Data Format)
4,800
This is the format for most handheld GPS receivers. Loran
must have sentences RMA & RMB. GPS must have
sentences RMB & RMC.
Aviation Data
Format
9,600
“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.
Northstar
(Northstar
binary)
1,200 M1 setup select “NO EXTENDED”, “NAV ONLY”
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-960)
Compatible with RS-232, TTL, RS-423, RS-422 SDA. Serial
data format: 8 data bits, 1 start bit, no parity. Baud rates: 1,200,
4,800, or 9,600 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-960)
RS-232. Serial data format: 8 data bits, 1 start bit, 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.
