I am trying to connect my Denon 2808 AVR to my GC-100-12 via RS232. I used a normal and a crossover cable (2 and 3 switched), but cant get a single response from the AVR. I connected it to Serial1 on the GC unit and used iTest to send commands. Settings for the serial port are according to Denon (9600, no flow control, no parity). No command I send seems to work (PWON, PWON<CR> and some others i tried). Needless to say that using an app for controlling the avr doesnt work either ...
Any suggestions what I might try?
Kind regards, Florian
