Serial object connecting to beamer


    Jan 30 2013 | 10:10 pm
    Hey,
    I'm trying to switch a beamer on/off using the serial object without any luck.
    I can select the right port called USB-Serial-controller and I set the correct baud-rate and other settings.
    The only thing i get out of serial object is 'read 0' and 'write' (out the right outlet).
    I attached images from the pdf of the serial messages of the Optoma GT750.
    Don't know if the codes i send are correct,.. i attached the sample patch
    I use this serial to usb converter: with a PL-2303 driver v.1.4.0
    I tried also another beamer without any luck. Even when I turn on/off the beamer manually nothing is coming out the serial object, what normally suppose to happen because RS232 is handshaking, right?
    Any clues or suggestions? Thanks in advance!

      hi, I don't know much about the topic, but the word "beamer" is a so-called pseudo-anglicism for "video projector", and isn't really used outside of a few european (non-English-speaking) countries.
      I hope you don't find this condescending, i don't know, I was thinking that this might help your googling a bit.
      good luck,
      Andreas

      thanks for the tip, i will keep that in mind,..
      although I googled for solutions also with 'video projector' it's good to know.
