Hi all,

I am writing a code to a DVX-2150HD that have 2 hdmi outputs,
and I am thinking if is there a way to send CEC commands to turn on, to change input , etc, from netlinx, to the TV connected on this HDMI port ??? the same situation if i have TV connected on HDMI output of the DXLink™ HDMI Receiver ??

Anyone work around these ??


thanks in advance

    CEC commands only allow power on/off, volume mainly, change input so long it's some HDMI inputs (not tuner for example) and it depends of capabilities of device you want to control, results are very different depending of manufacturers !
    As far as I know, none of the AMX devices have CEC capabilities unhappy :(

    Given the fragmentation that CEC has suffered since its inception, I just don't see it as a viable/reliable solution for professional integrators. The manufacturers have done their best to break the original intent behind CEC, which was an open standard for HDMI devices from different manufacturers to be able to communicate. They've all taken the opportunity to create proprietary ecosystems in which only their own products work reliably. And even that isn't true in most cases.

    All of that said, when I have CEC controls at my disposal, I will always rely on RS232, IP, or even IR (*shutter*), over CEC.

    Stuff like this hasn't stopped the industry before. Hence my favorite saying: "That's the great thing about standards, there are so many to choose from."

    I agree with you on fragmentation but it's still very efficient once you have the correct command for control and feedback, as reliable as RS-232 so long you have the correct protocol ;) I use a box (Kwikwai) that allows to listen and snif CEC commands and so it makes the work a lot easier !
