This past weekend I was setting up some new wiring for my Trio A/P. Goal was to get a new set of wires from the 430 and GRT AIRINC outs to a select switch, then to the trio head. Looking at the 430 wiring diagram, it has only one AIRINC channel out. I was surprised to find out that it was already pre-wired by Stark Avionics to the 330. I failed to notice this during installation and did not record this in my schematics.
The 330 does take a serial input from the 430 for GPS position, to activate/deactivate the transpoder at a certain speed. Easy enough to understand. What I cant figure out is why the 330 needs, wants, or desires the AIRINC data stream off the 430. Any ideas?
AIRINC being a serial data stream, I spliced into it and teed off a set of wires for the a/p function I need.
I turned off the AIRINC data output from the 430 and could not see and difference in behavior of the systems. Perhaps when no AIRINC data is received from the 430, it uses the 232 serial for gps speed data?
The 330 manual says the AIRINC input starts and stops the flight timers, as well as puts it in ground mode when landing. Hmmm. I thought the serial input from the 430 did that. It does not say that the AIRINC data put the 330 in atl reporting mode. Just says it puts it in gnd mode. hmmm.
Thoughts on why the 330 would enjoy the firehose of data off the 430 AIRINC data stream? I feel like there is something important im missing.
Thanks
