ARINC 429 TO NMEA0183 RS232 RS422 DATA PROTOCOL CONVERTER


ARINC429 to NMEA0183 Data Translator Protocol Converter extracts navigational data from an
ARINC 429 data bus and translate it onto an RS232 or RS422 serial data bus.

The exact format for the converted data is NMEA0183 - a marine GPS ASCII format. 
The typical labels processed by this converter are shown in the table below. 

The converter adapts automatically to high or low speed (12.5/100kHz) ARINC 429 data and the inputs are opto-coupled for electrical isolation purposes.
The unit is powered from an external 28 VDC (18-36V) nominal supply with internal current and thermal fuse. The inputs are also reverse polarity protected.

ARINC429 Labels Configured :-

 

ARINC429 Label Description of Label Format
125   UTC (GMT) BCD
147   Magnetic Variation BNR
260   Date BCD
310   Latitude BNR
311   Longitude BNR
312   Ground Speed BNR
314   True Heading BNR

The output data is in the form of RS232 or RS422 serial data transmitted at a rate of 4800 baud. 
The output string is in ASCII and conforms to NMEA0183 data standard. 
Examples of the output are shown below:

  • Each line begins with a '$' and ends with a CrLf (0DH, 0AH) characters.
  • The ',' comma delimiters are used to identify each particular field.
    i.e. Third field is Latitude, fourth field is 'N' or 'S' indicator.
  • Each line is transmitted at 4800-Baud Rate and at a repetition of one line per second.

The connections for the are via a D9 filtered plug as follows:
