[Dx4win] Using PSK and ICOM IC756 Pro II

[Tony Lord]

Hi all, I am wanting to use PSK (and other digital modes) with ICOM
IC756Pro II. Can I check connections with someone to the ACC1 Socket on
rear panel. Clearly I need audio in and out from my sound card. Looking
at manual, Pin 5 is AF out, that's easy to line in/mic of soundcard.
Regarding audio in (output from sound card) I have two options (I
think).

Pin 1 = RTTY
Pin 4 = Mod

My software say connect audio in to RTTY terminals (pin 1), but looking
at radio manual I think Pin 4, Mod is correct. Can any one comment,
please! Thanks.............
