Looking thru the latest QCX manual, I can not seem to find docs on the CAT pins. What pins are RX and TX on?
Probably in the manual? Nothing on the schematic. I assume these are TTL levels and a RS-232 to TTL converter will do the job.
I just flashed the firmware to 1.05. Attached is a pic of my old QCX with a laser cut case that I made years ago.
Looking at the schematic, I need to add 2 resistors, 1 diode, and a header
Has any one done this upgrade? A pic with the suggested placement of new parts on the older rev board (and the new CAT header) would be great.
Thank you for reading my post.
