can anybody tell me, if it is possible to realize / install a separate cat jack without using the present USB port,
by going straight to Pin 1, Pin 2 and Ground on the Arduino Nano?
If I have understood correctly the built in cat interface in KD8CECs firmware uses the USB connector
just as an RS232/TTL converter
Am i right, if I assume, that it should be possible to solder some wires to D0 and D1 (RX + TX) and ground and then install
a MINI-DIN 8 socket to the uBITX like in an FT817?
I am asking because I am building TF3LJs Magnetic Loop Controller https://sites.google.com/site/lofturj/to-automatically-tune-a-magnetic-loop-antenna at
the moment, which communicates with the tranceiver via cat for tuning the antenna. This interface uses just these three lines. So I need to make them talk :-)
I would just try it, but am a little bit unsure if i might damage something, if I am wrong. I am not really fond of grilling the Raduino.
