ALSO posted in RTI forum...
Hi all, up late programming and about to pull my hair out. Does anyone have experience controlling a TOA D-901 mixer via RS-232? I'm following the protocol and not having any luck.
RTI RK2 with RP6 and CM-232.
I've checked pin-outs and that's fine, and I've tried a few variations on the commands, to no avail. Example:
For output channel one, volume step up by 3, here's what the spec says:
91H, 03H, 01H, 00H, 43H
Where 91H is the command, 03H is data length, 01H is channel attribute (output channel), 00H is the Channel Number (one), and 43H is a 3 step up in gain. By the book.
And that's all it gives ya! Anyone have any tricks they can offer?

Could be a few things. Depending on how the RTI system likes to see strings expressed. The Crestron module spits out the following string to raise the volume of output one a single increment step:
\x91\x03\x01\x01\x41
Baud rate 115200 8, 1, none

Got it running now, thanks for the help! Manual was a bit sketchy on command strings, if you enter it as thus in HEX mode:
91 03 01 00 14
It works fine. It essentially turns into what you have above when you switch over to ASCII.

Hiya-
I am in this situation currently with a 9000 M2 and have limited control with RTI. I have about 6 working commands and am unable to shut off phantom power or turn channels on or off.
Do you have any further examples you could share (that work).
Thank you,
Alex
