4.6.1.1 RS-232
The 500W Series unit is capable of interfacing with other aviation instruments by transmitting RS-232
Type 1 (often known as ARNAV format) and Type 2 (often known as Northstar format) data on the GPS
RS-232 OUT 1 port. The data consists of the following (refer to Appendix D for a detailed data format
description):
•
Current latitude, longitude, and GPS altitude in feet (see Note below)
•
Current velocity vector (ground speed and direction of velocity vector over the ground)
•
Distance to waypoint
•
Cross track error
•
Desired track
•
Destination waypoint identifier
•
Bearing to destination waypoint
•
Magnetic variation
•
Navigation and warning status
•
Waypoint sequence in route
•
Waypoint position (latitude and longitude) and magnetic variation
NOTE
Aviation RS-232 data may be transmitted with or without the current GPS altitude in
feet. Refer to Section 5.3.2.
The 500W Series unit can receive pressure altitude, air data, and fuel data from certain systems on the
GPS RS-232 IN 1 port.
The 500W Series unit can communicate with a Ryan TCAD 9900B system using the GPS RS-232 OUT 2
and GPS RS-232 IN 2 lines to display traffic information on the 500W Series unit.
If two 400W or 500W Series units are installed in an aircraft, the GPS RS-232 OUT 3 and GPS RS-232
IN 3 lines may be cross-connected to crossfill flight plans and user-defined waypoints from one 400W or
500W Series unit to the other.
NOTE
The GPS 500W/GNS 530W will crossfill with other GNS 400W/500W Series units only.
It will not crossfill with the GNS 480 or older GNS 400/500 Series units.
The 500W Series unit can communicate with an L3 Communications WX-500 Stormscope using the GPS
RS-232 OUT 4 and GPS RS-232 IN 4 lines to display lightning strike information on the 500W Series
unit.
