Oppo UDP-203 rs232 control infos

Hi, someone experienced rs232 control on the latests Oppo?


I'm using an old (but gold..) Nevo S70 + Nevo Connect remote and i'm controlling, with no issues, with an Ada Suite 7.1HD, an JVC DLA-X70 (both with hex serial command) and one Denon DBT-3313UD (in ascii serial).
Now i'm tryng to control my UPD-203 without success


reading the original Oppo rs232 manual:


http://download.oppodigital.com/UDP2...l_Protocol.pdf


control must be something like:


#POW <CR><LF> (on Denon Bluray, as example, same working command is: KYPW ON<CR>)


or


0x23 POW 0x20 0x0d 0x0a


but both are not working.
Any help/suggestion/working command will be really appreciated.
Thanks

Are you using a ‘straight through’ cable to connect to the Oppo? It won’t won’t on null modem cable.

Thanks for your reply,

I have compared the connections between Oppo and the working Denon serials and are the same (standard pinout)

Ok. I will dig out the code I use and share it later.

Great. So it does require a line break at the end. That was my suspicion. My Lyngdorf is the same yet the manual doesn’t state it.
