The issue I’m running into is that for a generic “serial port X”, you select an input/output type such as TT22/EchoUAT, NMEA GPS, etc...there is not an option for the Echo box by itself. The only options that seem to exist involve combining its signal with some other input, i.e the serial port combiner or a tt22 signal. I haven’t been able to find an input assignment that generates any activity in the input counter. The Echo box itself is receiving power and functioning because it is supplying ADS-B in data to the EFIS and I am able to connect to the Echo’s WiFi network to access device configuration. I’m stumped.
