Serial Control of a LCD/Plasma Display?



I'm in the process of installing several digital signage displays and have just recently came across the Roku line of products including the BrightSign device. I'm quite impressed and will hopefully be buying dozens of these in the VERY near future. Unfortunately, my displays will often be in locations where I will need an automatic on/off of the LCD display device. With the scripting language for the BrightSign, is there a CLOCK-BASED command I could send to the RS232 for powering/waking up a LCD display device (and for shutting it down overnight)?

    you can send out strings over the serial port to a display with brightsign.



    The current brightsign hd600 does not have a real time clock, so it does not know what time it is.  This is something we plan to address in the future, but I have no specific date.



    You could use a low cost single board computer with real time clock to turn the lcd on and off, and it could also comunicate with the bright sign via rs232 or the gpio port.



    for example (never tried it): the QCC and QCC-RB at http://www.mosaic-industries.com/cgi-bin/PriceSheet.cgi?QCC



    thanks

    The Single Board computer has to be compatible with the display device though, correct?  The other alternative is to use PC-style monitors that go into a hibernation state (the orange led power light vs. the green led power light) and consume micro amounts of electricity in their hibernation state...



    Hmm... Ok....   I guess I just have to find the proper display.  Do you have a suggested single-board-comptuter modifiable display that you would recommend in the 27"-60" range?  (maybe this should be its own topic.. sorry..)..

    lakeiser,



    I don't know how flexible a solution you need, but they do make surge suppressors/power strips that have 24hr timers. Some are light sensitive, but there are some others that allow you to specify how long you want the power to be on before it shuts off.

    Could you tell me how to send out strings over the serial port with brightsign?

    And, how to set the Baud rate, the parity bits and stop bits?



    Thanks.
