Have a SV1000 system with SV-XPNDR-261, GPS-250, ARINC-429, Avidyne IFD540 GPS NAV/COM and a Garmin GTR200 Comm. I am having a problem with the -261 seeing the RS232 IN on pin 3 from the IDF540 in either the aviation format or the ADS-B format. The GPS-250 input selection works fine and I see ADS-B weather and traffic, however selecting the -261 GPS Input source to Aviation or ADS-B (from the IDF540) results in no data being detected. I placed a break-out box at the -261 connector and was able to see data streams in both the Aviation output format (9600,8,1,N, No control) and ADS-B format (38800, 8,1,N No control) from the IDF540 to the -261 using a RS232 analyzer. The pin to pin ring out also shows a good 1.2k ohm reading. I am running 12.2 SW and upgraded the -261 with the latest load. Any ideas on why the SV1000/-261 is not seeing any 232 data from the 540?
Also, is there any way to verify if the ARINC-429 is seeing the RS232 Aviation format IN from the IFD540?
Thanks.
