3.2.2. Type 1 Format (ARNAV Format)
Electrical Interface
The output signals will be compatible with RS-232C. This format will generate data at
9600 to 115200 baud with a word length of 8 bits, one stop bit, and no parity. Once the
baud rate is determined, it will not change.
The RS-232 data will have the following general format:
STX
ASCII start-of text character (02 hex)
T1s
Type 1 sentences (see following paragraphs for description)
T2s
One or more Type 2 sentences (see following paragraphs for description)
ETX
ASCII end-of-text character (03 hex)
Output Sentences Type 1
The Type 1 output sentences shall have the following general format:
Id
item designator (single ASCII alphabetic character)
Dddd
item data (1 to 10 printable ASCII characters)
CR
ASCII carriage-return character (0D hex)
LF
ASCII line feed character (0A hex)
Each Type 1 sentence will be output by the unit at least once every second. The track will
be output in True (not magnetic) degrees.
Output Sentences Type 2
The unit will receive Type 2 sentences that will have the following format:
Id
item designator (three ASCII characters)
Seq
sequence number (1 binary byte)
Wpt
waypoint identifier (5 ASCII characters)
Lat
waypoint latitude (3 binary bytes)
Lon
waypoint longitude (4 binary bytes)
Myar
magnetic variation at waypoint (2 binary bytes)
CR
ASCII carriage return character (0D) hex
LF
ASCII line feed character (0A hex)
