I can imagine. I had a URC-300 that drove me to drink because it wouldn't learn codes.

Silly question but when you're learning the codes are you in the same room as the equipment or in a different room? Sometimes that can make a difference.

Good thought, I moved to another room but still no luck. Here is some more info, maybe a Hex Guru can decipher this. I have a Marantz 3200 remote that does switch my matrix box, here is how a code looks in the Marants for one of the inputs of the switch:

0000 006E 0024 0002 0152 00AB 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0015 0015 0040 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 05DB 0152 0055 0015 0E30 0152 0055 0015 0E30

I then copy pasted this into my 7500 and it worked it looks like this (it did not change):

0000 006E 0024 0002 0152 00AB 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0015 0015 0040 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 05DB 0152 0055 0015 0E30 0152 0055 0015 0E30

It did not change the code. When I learn this same input on my 7500, it looks like this and does not work:

900A 006D 0000 0001 20DF 00FF

This was the only input I was able to get to work, I copy/pasted the other codes from the RC3200 but they did not work in my 7500 even though they work in the 3200.

Thanks, Bill

I want to make sure I'm really understanding you:

In the same 7500 remote that long sample of Pronto hex (starting 0000 006E 0024) worked? And the short on (starting 900A) didn't?

They represent the same IR signal. There is a tiny difference in modulation frequency (the 6E vs. 6D) that I'm certain does not matter to the actual device. (I don't know whether that 6E matters to PENG when you paste in a long code and PENG decides whether or not to convert it to a short code).

I wonder if you have somehow corrupted the firmware in the 7500 so it no longer knows how to transmit codes beginning with "900A". I know only about the IR signals, not about the firmware: Do you have the 7500 firmware on your PC? If so, can you get a new copy online somewhere in case the copy on the PC is corrupted? Can you reload the firmware into the 7500?

Anyway, if the long form works, it shouldn't be too hard to construct long forms that work for all the signals. But even rereading this thread a couple times, I can't follow what you've done so far and what works vs. what doesn't.

For example in post 15 you name one thing "Video Output 2" and show four different learned signals. What is the relation of those four signals to "Video Output 2"?

In posts 9 and 11 you show an insignificant change made by PENG to a long form signal, then I think report that it later changed again, this time to the short form. Does it really take transfer to the remote and back to make the second change? In other threads people have described situations in which PENG steps a signal through multiple forms. After you look at it each time and press OK it stores it back in the next form, so if you look at it again (or use it) you have the next form.

John, here are my answers:

---Yes, the long code works, the short code does not but that was when I used the 3000. When I had to move to the 7000 they stopped working. I had to work a lot with the 3000 to get it to work. In fact, the matrix switch has other outputs that I could not even get to work and had to stick with Vid Out 2.----

---I can try this but I have a 7000 and 7500 and neither work this particular matrix switch. Can both of these be corrupted?----------

For example in post 15 you name one thing "Video Output 2" and show four different learned signals. What is the relation of those four signals to "Video Output 2"?

---This matrix switch has 4 inputs it can switch for each of its outputs. Those 4 signals represent each of the discrete inputs for Video Out 2, and only 2 of them worked------

---It only changes it to the short form when it learns the signal ---

One other note, I have a MX500 and MX950 and both of these work the matrix switch with no problem, could there be something with this particular frequency that this Matrix switch uses that is causing problems?

How am I misreadind that statement?

Or am I misreading that?
