Hello Everyone,
I want to control my TV (Toshiba 32ZT29B) from the computer via rs232. The computer is interfaced to cctv cameras and motion detectors. When motion is detected, I want to switch the tv to display computer screen and hence cameras. The PC has s-video output, which (through converter) i've plugged to the scart socket.
I see two ways to do that:
A. Use the serial port at the back of the TV.
B. Use SCART pins 10, 12, 14 (http://www.diyha.co.uk/electronics/scart.html). In theory, it should be possible to control the TV behaviour using serial communication on those data lines.
I have asked Toshiba for the specs. of the supported commands, but after a months wait I’ve got an email saying they can not provide me with this info... bull&£$%. I think this is because the serial port on the back of the TV is most likely used for servicing purposes (firmware updates). However, SCART should have some standard command set to interact with DVD players, video recorders and satellite receivers (possibly cinemalink functionality).
Does anyone have any specs on the scart command set, line levels, baud rate, parity and stop bits? Has anyone tried to use those for control of their A/V equipment? Anyone tried to use their serial port (D-Type 9 pins)? Has any of you experts got some other idea how to accomplish such goal.
Any help will be greatly appreciated.
Thanks,
ARK
