McIntosh C2700 RS-232 protocol wanted

[lukas.polivka]

Hi!

Does anyone have the serial protocol documentation for this device? I tried looking for it on the manufacturer's website without success.

A dealer tried using the driver for C2500 but it does not work, some of the commands are different. I was able to figure out only some of them.

First of all, the commands do not specify any zone (Z1, Z2) so the string matching patterns had to be modified.

Then instead of VST num it uses VOL num to set volume level, PWR 0 and PWR 1 to turn it off/on instead of PON and POF. I wasn't able to figure out the volume up and volume down commands.

And inputs are behaving erraticaly. If you choose an input using the front panel dial, you get e.g INP 9 back, but when you select input 9 using INP 9, the device returns INP 9... but actually always switches to an input that's IIRC one higher (or lower).

Nevermind, seems like the manufacturer already has a working driver (written by BlackWire Designs, but it's not on either website for some reason). As far as I can tell it's free. So just contact your supplier/distributor/McIntosh directly.

Did you ever find a driver?  We need one as well.
