Control A/V Rotel RS232

[archived]

HI
I've got a A/V amplifier and a DVD from Rotel with a RS232 interface. I saw design template for Denon but Rotel for control their appliances uses hexadecimal character. For example to implement Power ON the code is:
0xFE 0x03 0xC3 0x75 etc .How can I write these 'control char' in a DCE device?
Thank you for your suggentions!!

Many of Denon devices are implemented as "Generic Serial Device" which has a very powerfull interface, but for small things like yours there is a simplified syntax.

Take a look for example at Denon DVD-A11 (just add it as a device, got Wizard->Devices->Generic Serial Devices" and click on "Ruby source Code", you can delete it later, after you see how it's done there).

You'll see on ON command something like

<$"PWON\r"$>

Which practically means send that string.

In your case you can write something like

<$"\xFE\x03\xC3\x75"$>

Hope this helps.
