I'm struggling to directly access my sources through the serial port. Using CCP and according to the guidelines from McIntosh it should be !SRC and then the source number. Have tried everything and I'm sure it's something simple (or stupid) that I'm missing. Everything else works great, and I can access the sources just fine using the IR data, it's just a little janky to have a flasher on the front of this gorgeous piece of equipment.

Thanks in advance for any help.

What base station are you using to send the RS232 strings?

By the way, that model has an IR jack on the back. So you do not need an IR flasher on the front either.

Hello Brad,

I'm using a MRX-2. Good point on the IR in jack. Absolutely everything else works but those direct source commands.

So you are trying to program the CCP app to control RS232? Or do you have an old MX-5000 or KP-4000?
Those 3 products are the only way to use the serial ports in CCP.

Have you tried using the RS232 codes for McIntosh in CCP? Code 1236?

Also, default Baud Rate on the MRX-2 is 9600. The McIntosh wants 115200. So you need to click on the serial port properties in CCP and change that.

I'm so stupid, it works fine and the answer was right there on the docs from McIntosh. All good now, thanks again for the help.

What about the MX-6000?

Well, if you can get it to connect to CCP then that would work too.

I had a like new MX6000 last year a customer gave me. I tried everything I could to get it to connect and it just wouldn't. A few of those tricks I tried came from here at RC.
In the end, it seemed the only way to get it to work was using an old version of Windows and I no longer have access to anything like that. So I tossed it (made me sad).

Come to think of it, doesn't the MX5000 have the same connection issues (needing a certain version of Windows, Sync, or something)?

I don't know. I will go back 10 years in a time machine, and then from that point try to remember back :-/

I tried to make an MX 5000 work with RS 232 and it was a constant service call. I put in quite a few of those remotes, but I always used them in RF and IR modes.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
