USB-UIRT and LCD projector

[specter333]

Hi again, next item on the "I can't figure it out" list. This is probably not an EG issue but maybe someone here can help or point me somewhere else.

I'm using an Epson 710c LCD projector and have it and pretty much everything else in my house controlled from a Phillips universal remote through EG and USB-UIRT. The universal remote triggers macros in EG which in turn sends the IR through USB-UIRT. I can power on the projector just fine but can't seem to get the remote to power the projector off again.

When powering off, using either the original or universal remote, after the first button press the projector displays a message "Press power again to turn off". When I press power a second time on the universal remote nothing happens. I've tried this a few different ways.

1. I've tried simply transmitting the same code again by pressing the same button on the universal remote again.

2. I've tried learning just the code from the second button press on the original remote and transmitting that after a 2 second pause.

3. I've tried learning the code from the second button press and assigning it to another button on the universal remote. I even learned the code for this one while actually turning off the projector so I know it captured the correct code. I even tried this method in raw mode.

No matter how I try the projector never gets the power off message from the usb-uirt. Does anyone in this forum have any ideas?

Thanks again for any wisdom you can send my way.

2 things I would do to start off.

1st ask this over at the USBUIRT forums, much knowledge there too.

2nd take some of your known working Hex codes and google the hex against the command. If you are lucky it uses something else's codes.



I don't think it has discrete on/off so I am suprised what you are doing isn't working.


What happens if you try:

Code: Select all

<?xml version="1.0" encoding="UTF-8" ?>
<EventGhost Version="908">
    <Action>
        System.MonitorPowerOff()
    </Action>
</EventGhost>

or

Code: Select all

<?xml version="1.0" encoding="UTF-8" ?>
<EventGhost Version="908">
    <Action>
        System.MonitorStandby()
    </Action>
</EventGhost>

?

Hi again Collin, USBIRT forums, now there's one of those obvious things I didn't think about. I'll certainly look over there. As for the second part of your post, it's above my head. I don't know where or how to try sending any code.

Like you I am surprised this is an issue. It doesn't seem logical that the projector would recognized the first signal from the USBUIRT but not the second. Hopefully it's something simple I'm overlooking. Thanks again, Rich

Just drag you mouse over the code inside those boxes, copy it and paste it directly into EventGhost where you would normally be tring to put the Power Off action.

Those commands will be send to the projector via the VGA cable using the power conservation stuff.

Ok, very interesting, I didn't know you could add code that way. That brings up even more ideas. Unfortunately it didn't work for this problem. Both methods make my other monitors flash and come back on but did nothing to the projector.

I've spent the last few hours charting out samples of what code EG is receiving from the original remote. The only thing I can tell from it is the code isn't always the same, but doesn't necessarily change every time either.

I did figure out that EG can send either one of the two off commands but not both. I programed my power button on my learning remote with the code from the original and set up a macro that triggers from that code and sends a second off code 2 seconds later. Realistically that works, when I push power on the learning remote it sets the projector into the first power off stage and triggers EG to send the second IR signal.

For my unique purposes that doesn't work because I trigger other events from the lcd on and off macros. Of course the quick fix here would be to send the off command from another button but I was wondering about the "Make Exclusive" feature. How does that work? Is it possible to make the same IR trigger control either the power on or the power off macro exclusively and still be able to do a hundred other thing with the remote between those two events?

The other strange thing that's happening is that every time I push the power button on the universal remote EG logs a different event. To get the macro to trigger almost every time I've dragged 12 different events to it. The projector responds to the remote every time so I'm not sure why it's always different in EG. Is this a normal thing for a remote to do?

I looked through USBUIRT forums where I found a link to Remote Central forums which is where I got the idea to chart the original remote and look for a pattern. I haven't posted in either of those yet and if the Make Exclusive things works out I'll probably just call it good enough.

By the way, I was driving through Tulsa today and it was cold up there. It was nice when I left Miami and it's nice down here, you must have had a cold front come settle on just Tulsa.

Thanks again for you help. Rich
