Pioneer PDP-LX508 & RS232?

Postby alexd » Fri Feb 08, 2008 6:34 am

Has anyone had any success in controlling the Pioneer PDP-LX508 via RS232?

I have tried all sorts of different command formats and haven't had any success at all in sending any commands whatsoever.

The screen is set to 9600baud via the integrator setup menu (home menu, then power button), but this doesn't seem to have any effect. (The baud rate is the only option in the integrator menu, there are no other options. I have seen some comments on other threads on the net regarding having to disable the IR on the screen so that it knows to listen to the com port?)

Any suggestions, or has anyone definitely been able to send commands to this screen?

Thanks
Alex

Alex:
Do have the command set. I was able to control 42" and 50" Pioneer Elites. The elites use a strange combination of hex and ascii.

Tracy I have a couple of different command references although they all seem to be very similar, these are the ones I have tried using:

I dont seem to be able to get an comms from the TV, I believe it should sent back error response if I send it something incorrect, can you confirm?

Thanks

Looks like it similar to the Elite series of TVs. The command format for MLGD is:

Code: Select all

<<\02>>**PON

Use a command terminator of 3. I expect once you figure out how to get the TV in the RS-232 acceptance mode you will be fine. Looks like a really nice control set.

From what I remember working on this project, the hardest part of the project was getting the TV to accept the commands. Once that was completed, it was down hill from there.

The Pioneer Elite 42 and 50 control sets for MLGD are posted to MLInstaller as downloads

In case anyone else ever tries to connect and control this screen via rs-232 I have found the answer!

It uses a straight through serial cable, not a null-modem cable as I had originally been trying!

Also, this screen does not require any special command or mode to get it into serial mode, it is apparently always listening and responding to rs232 commands, and it will therefore respond to both serial and ir commands simultaneously, thereby allowing the user to use either form of control mechanism without having to do go into any special menus or set anything up.

Regards
Alex

Were you able to control it using MLGD? If you need help when you get further into, let me know.
