Panasonic Shutter Control via rs-232

I have a real simple presentation that I am working on and cannot get the serial commands to work. The project is a static image as the home screen when gpio button 0 is press it plays a short video file. When file ends its to return to the Home screen. I am using a Panasonic  PT EW630UL projector and a HD1010 player the 2 are connected by a serial cable. What I am looking to do is with the press of the button 0 I want to send the shutter off command OSH:0 allowing the shutter to open to allow the video to play and then at the end of the presentation as it goes to the home screen I want to send serial command OSH:1 to close the shutter. In short we want to be able to leave the projector on and use the shutter to quickly show video and then close upon end of video with player left in a standby state showing the static image. I just cant get the serial command to work. Any one have any experience or thoughts on this?

    Is the brightsign unit connected with the projector via a null modem cable (cross cable) or a standard serial cable? It has to be a null modem cable.

    Please download a free program called Hercules from this page:
    http://www.hw-group.com/products/hercules/index_en.html
    and install it on your PC.

    Connect your PC to the projector using a null modem cable. Open Hercules, click on Serial, configure serial port, click Open. Send serial commands to the projector. If you can control the projector from your computer, please send the screenshots of what commands you send from Hercules. Hercules would make it clear as to what exactly needs to be sent from brightsign. Then we can proceed with building a project in BrightAuthor.

    You can try the option:
    send - serial bytes (comma separated)

    for shutter on you type this string:
    02,90,90,59,79,83,72,58,49,03

    and for shutter off you type this string:
    02,90,90,59,79,83,72,58,48,03

    Well no luck with the serial bytes. Must be the cable I am off now to the store to get a Null cable and try again. I am running a straight cable now. Another thought running the serial bytes can I go out port 1 on the HD1010 with an IR emitter to the projector?

    HD1010 supports IR remote control, but there's no IR output setting in BrightAuthor. The only IR output currently supported is via the USB IR transceiver we support from Iguanaworks. You would need to write a custom script to send IR commands from the HD1010.

    You can send a kill signal command (Powersavemode on) or a restore signal command (powersavemode off). It would put a display/projector into standby by turning off the video signal from the brightsign. Take a look at this FAQ:

    Ok, I have tried every setting I could find in the Hercules and I am still unable to control the projector but I found Microridge Comtestserial http://www.microridge.com/comtestserial.htm and I am able to control the projector just fine. I will attach a screen shot of the commands I am sending. Hopefully we can make this work. I really need to use the built in shutter option

    If you are able to control the projector from PC by sending

    02 4F 53 48 3A 30 03

    and

    02 4F 53 48 3A 31 03

    Then you need to send the decimal equivalent of hex codes in BrightAuthor using the Serial bytes (comma separated) commands.

    2,79,83,72,58,48,3

    and

    2,79,83,72,58,49,3
