USB-UIRT Forum

Hi Jon,

First off, thanks for a great product (and service)! Based on what I've seen of your activity in this forum, the girder forum, and the avsforum, and I'd like to thank and congratulate you for your excellent contribution to the HTPC community.

Now, on to my small problem. I've noticed that girder thinks it's receiving different eventstrings from the same button on my RCA remote, depending on how long the button is held for. When the button is held for too small an interval, girder doesn't recognize the command. Obviously, when I get the timing just right, the eventstring is recognized and the girder command is executed. "Just right" in my case though, is too long. Having to hold the button down for 1/2 - 2 seconds makes adjusting volume or flipping through channels rather tedious.

Any ideas?

If you're seeing what I'm thinking you're seeing, it behaves like this:

*When you press a button for a very short period of time and release it, you get a Girder event (the Girder light blinks and a code appears on the Girder status line).

*When you Press the button for a longer duration, NO girder event shows up for about a second or so, and then a single event appears.

Is this correct?

If so, this is similar to a Dish Network remote I have used. The issue is that the remote 'streams' IR data rather than sending bursts. Because of this, there is no 'pause' which tells the USB-UIRT that the code is finished. So, the USB-UIRT will only pass an event back to Girder after its built-in timeout (otherwise it wouldn't ever send a code until the button was released.

That's almost it.

Point 1 is right on, this is the "short case" that I've seen. Point 2 is correct as well, this is the "long case" that I've seen, where if you never release a button you get a girder event after about a second, but no subsequent events, even though the led on the remote indicates it's sending. There is also a "medium case" in which you hold the button maybe twice as long as you would in the short case, and then release, and then get a girder event.

Although this is probably not what you want to hear, my first recommendation is to try using a different remote protocol. If your RCA remote can be configured to emulate another brand, that would do it.

Since the USB-UIRT is not specifically programmed to interpret a particular protocol, the streaming protocol your RCA is emitting is going to be troublesome for the reasons described earlier.

Please let me know if this is an option.

It's an option. I'll try another brand and post back if I'm still having problems.
