Has anyone had any experience with sending CINEMA control through a BeoSystem 4? The instructions (as usual for B&O) are quite lacking. I currently have a 9-pin cable going from my BeoSystem 3 to a board that I configured to reassign the pins to what need to go to a Linronic code-converter setup to translate the data signals sent from the CINEMA control to trigger the Lintronic box to send out an IR signal to lower/raise the projector screen. (My projector does not have a 12-volt trigger to control the screen.) This has all worked perfectly for me.
However, how does the BeoSystem 4 handle the CINEMA signals? Does it send all CINEMA signals through one RJ45 control port or are they separated to multiple RJ45 ports? Is there an RJ45 to 9-pin (is it called RS232?) cable that would give me the same pin configuration as that of the BeoSystem 3 CINEMA output?
Update:
BeoCare has become just ridiculously useless. It seems that it is now impossible to phone B&O tech support in the U.S. BeoCare provided me a few pages from an installation guide, but refused to provide the entire guide. It seems that it's a "top secret" guide in the eyes of BeoCare. After some searching of the internet, I was able to find a BeoSystem 4 / BeoVision 12 installation guide that is hugely helpful. It seems to be a different guide from the one with the few pages that BeoCare provided. Still, it's helpful in that it shows the PIN outs of the RJ45 connectors. I would be happy to share this with BeoWorld to upload to the manuals sections if I had the correct email to send it.
From what I understand now, the BeoSystem 4 has up to four "open collectors" for CINEMA control. There is also a control for hotel use. I now know the correct pins and could fashion an adapter to a 9-pin cable that was used for the BeoSystem 3 CINEMA control. What I don't know is if the "open collector" is the same thing as the data signal send out by the BeoSystem 3 for CINEMA control. Does anyone here know?
From the pin diagrams, it looks like the same RJ45 ports could be used for CINEMA control as well as the PUC A and PUC B, provided that the correct cable is constructed. If anyone believes this to be untrue, please let me know.
I'm sure that Steve at Sounds Heavenly could easily make these custom cables. He is amazing!

Hi Beojeff,
Thanks for your kind words! Yes, I can build these cables for you. The Control port should be kept separate from the PUC outputs, the Control is basically an RS323 connection to switch a display on or off, whilst the PUC sockets give 38kHz infra red signals to operate third party products via remote control.
Please feel free to drop me a line via my sponsor link below and I will be pleased to help.
Kind regards, Steve.
Steve.

That is the guide that I was able to find. However, there seems to be another guide that could be useful. The nasty woman named Ina at BeoCare refused to share with me the full guide and only a few pages that made reference to other parts of the guide that would be essential.
Sorry, Ina is not ‘nasty’ - not at all!
I am sure several beoworlders will agree.
She did not hand out that document, because she is not authorized to do so.
I would have approached my dealer - who probably will have access to it.
If you have a good relation to him, it shouldn’t be a problem.

There is a tv - and there is a BV
This is what I could find - does that help?

I was finally able to create the cable connection to take advantage of CINEMA control with the BeoSystem 4. Michael and Linronic was very helpful. BeoCare was absolutely horrible to deal with. She had no idea how any of this worked and refused to get better tech support. My dealer was very upset with BeoCare about this lack of support and has complained of it to the president of North America's B&O division.
BeoSytem 4 has four open collector triggers. For open collectors one and two, you use the PUC 1 RJ45 socket. The pinouts are as follows:
Pin 1 Ground
Pin 2 Open Collector 1 out
Pin 3 Open Collector 2 out
Pin 4 Ground
Pin 5 IR-blaster current PUC 1A
Pin 6 IR-blaster current PUC 1B
Pin 8 Ground
Shield Data Ground
I used an RJ45 pinout board to run a wire from Pin1 for ground and a wire from Pin 2 for Open Collector 1 Out from the BeoSystem 4. To a pinout board for the Lintronic Code Converter, I connected the Pin1 wire from the BeoSystem 4 to Pin 5 of the Lintronic Code Converter and Pin 2 from the BeoSystem 4 to Pin 1 of the Lintronic Code Converter. Using Lintronic's App Note regarding CINEMA control, I programmed the Lintronic code converter to send out an IR command to lower the projector screen and dim the lights open using the CINEMA ON trigger. When CINEMA OFF is triggered, the code converter sends out IR commands to raise the projector screen and increase the lights.
So that I could still use PUC A and PUC B for IR control of other devices from the PUC 1 socket, I used an RJ45 splitter cable in the PUC 1 socket and plugged the RJ45 IR emitter cable into one part of the splitter. Everything works perfectly.
