Hi there!
I am trying to get my HTPC to send RS232 commands to my Rotel RSP976 but I'm not having much luck!
I purchased a PCI card that adds 2 comm ports to my PC (com3 & 4) and they show correctly in XP. I constructed the cable as outlined on this fine forum and I'm trying to use an app called Girder to send the commands. Once I understood the format the command messages needed to be in, I set one up to turn on the unit, and another to turn it off. However the 976 seems to be ignoring my commands.
Now, I'm fairly new using the serial plugin for Girder so I thought perhaps that might be an issue. After speaking with a colleague at work, I thought I'd at least try Hyperterminal to see if there's at least a connection there. Hyperterminal wouldn't even let me type anything in the window! The only way we could replicate that fault at work was to disconnect the cable. It makes me wonder whether the transmit "circuit" is faulty. If I fiddle around with some of the front panel controls on the 976, the output is shown in the Hyperterminal window which, to me, indicates that the "receive" circuit is working OK.
I have double and triple-checked the control cable, I've swapped com ports on the card, and now I'm just about out of ideas.
Can anyone tell me whether there's any way to find out where the problem might be, or is there any way to check that the 976 is even receiving my commands?
Any help is REALLY appreciated!!!!

..Unfortunately that's way beyond my knowledge base. If you don't get any responses from here, which I would find hard to believe with so many knowledgeable people around, I'd try shooting off an e-mail to Rotel's tech support. At the very least they're super helpfull and can hopefully help you troubleshoot the problem. Also try contacting whomever you got the app Girder from.
