I'm building my wiring harness for the 660 and GDL 39 in the basement. The 39 is set on serial A to the 660 on serial 2, using the Garmin data protocol. The 660 is alive and well, the 39 is connecting via Bluetooth to the iPad running ForeFlight. I can't seem to find any indicator that the 660 and 39 are talking along the serial link though. Currently I'm in the basement, so no traffic/towers are seen. So, is there an indicator or means to confirm on the bench that the two are talking? Thx.
