Got it to work with hyperterminal by typing [PON] and using a Null modem cable.
Thanks for the advice.

Now trying to find a linux equivalent to winterm/hyperterminal to test my Hybrid's comm ports because the ruby script is not working for me. I am not sure if the comm port settings are even correct in the Generic Serial Device setttings and I am not sure how to check them.

I have been entering the Ruby script in the <"xxx"> format so for power on it is <"[PON]"> but this is not working for me so I will continue experimenting. I am sure I have a good cable but not sure if I have a working comm port on this machine.


Thanks

There is not an option on the on-screen projector setup. The manual only states this:

4.  RS-232 COMPUTER INPUT
The RS-232C serial interface is provided for external control of the TransVisionTM from a central
controller, such as a Home Theater control computer, Smart Home automation system, etc.
For D-sub 9 pin connector pin-out and RS232 command list, please refer to "TransVisionTM TV2 RS232
Control" section.


Again, thank you for your help.... even though this is not a problem with LinuxMCE.

I am not sure if I should try my null modem again and just type [POFF] or [PON] or if I would just type poff..... ect.

Thanks in advance for any assistance.

Running Hybrid 7.10 install with an overhead HD projector as display device.
The projector is a Dwin Projector the Model is Transvision 2
It has a male serial port on the back and the users manual states that it can be controlled via RS232.
I went through the setup process to control this projector with LinuxMCE.
I tried sending the test codes via the admin website and the projector did not react in any way.
To rule out the software I decided to try to use my laptop with hyperterminal on it.
I tried null modem cables, straight through cables (with gender changer) due to male port on both PC and Projector and other cables that I was not sure of the pinout.
I get no response from this method either.

So, I know it is not a problem with MCE but was hoping someone here might know what to expect from a serial controlled device.

I have set all the settings according to the manual 9600,8,N,1 but I am not sure how a controlled device will interact, should I expect to get feedback when I type?

What is the typical cable used for serial control? Null modem cable... ect.

Thanks

I had this same problem with my Turtle Beach Montego DDL.
The audio portion would not play but I still selected next at the volume screen and was able to hear audio for the Dolby test, then the DTS would come up and I heard nothing. It turns out the DTS sample only works with the coaxial output and not the SPDIF. So if you are sure your card support DTS just select yes you heard it.

I was not able to hear audio from mp3's or from non dolby recordings so I went in to kmix and discovered that changing the master volume source to ac3 and selecting the appropriate line outputs for digital output corrected the problem.

Audio playback is working 100% after I do these steps but the mixer seems to loose the settings after being rebooted, not after router reloads. So this would seem to be a KDE or Kmix issue I will have to work on.

Anyway, before you go scrapping your whole install over this try changing some settings in Kmix with an audio CD inserted or some MP3 file playing so you can hear when audio starts working while you are in the mixer settings of kmix, which is easily accessible via the panel on the KDE desktop in the lower right hand corner.

Good luck.
