Hello,

I have the VRC-1100 media center remote control. I've read the ARC-1100 is the exact same remote sold under a different brand.

I'm using a USB-UIRT with HomeSeer. I can learn some of the buttons on this remote but not all of them. In particular, the Green "Start" button and the "Stop" button. I'm sure there are more that won't learn but these are the two I need to learn.

I've tried the lrnhelper app for the USB-UIRT but the results are no different. The learning process completes but transmitting the learned signal does nothing.

Can someone please help me troubleshoot this? Why would some buttons work but others not? Are there any other apps I could use to try to figure out what's going on?

Thank you very much for any assistance.

Mike

Probably not the right spot, but if you post a couple of the learned codes that do work, and the learned codes that don't work, we can try to find out what's different.

Hi 3FG,

Thank you for the reply and attempt to help. Where is a good place to post this question?

Here is a code that works. It's the down arrow below the OK button:

0000 006C 000E 000E 004C 0026 0026 0026 0026 0026 0026 0013 0013 0013 0013 0013 0013 0013 0013 0013 0013 0013 0013 0026 0013 0013 0013 0013 0013 0013 0026 0757 004C 0026 0026 0026 0026 0026 0013 0013 0026 0013 0013 0013 0013 0013 0013 0013 0013 0013 0013 0026 0026 0013 0013 0013 0013 0026 0013 0746

Here are 5 slightly different learned codes all from the same button that do not work. I was using the Green Start button for these:

0000 006C 0000 000D 004D 0025 0027 0026 0027 0027 0014 0013 0027 0014 0014 0026 0014 0014 0014 0013 0027 0027 0014 0013 0014 0014 0027 0027 0014 0750

0000 006C 0000 000D 004D 0025 0027 0026 0027 0027 0014 0013 0027 0014 0014 0026 0014 0014 0014 0013 0027 0027 0014 0013 0014 0014 0027 0027 0014 074E

0000 006C 0000 000D 004D 0025 0027 0026 0027 0027 0014 0013 0027 0014 0014 0026 0014 0014 0014 0013 0027 0027 0014 0013 0014 0014 0027 0027 0014 074F

0000 006D 0000 000D 004D 0025 0027 0026 0027 0027 0014 0013 0027 0014 0014 0026 0014 0014 0014 0013 0027 0027 0014 0013 0014 0014 0027 0026 0014 0748

0000 006D 0000 000D 004D 0025 0027 0026 0027 0027 0014 0013 0027 0014 0014 0026 0014 0014 0014 0013 0027 0027 0014 0013 0014 0014 0027 0026 0014 0745

As you can see, they're smaller, but I don't know what that means. I can teach the Start button to my receiver's remote but the USB-UIRT doesn't want to learn it. I don't understand why. Is there any other way to decode and/or create these hex codes?

Any guidance is greatly appreciated. Have a great day!

Mike

I imported your Hex into IRScope, and it reports that the working code is OrteckMCE device 21, function (OBC) 32. It also notes that the end frame is missing. Reading DecodeIR.html (v2.43 is released), we see that OrtekMCE is designed to send 3 types of frames with minor differences. A frame with P=1 is sent when the button is first pressed, P=2 while the button is held down, and P=3 when the button is released. However, most IR gear can only send two types of frames, and that is true of Pronto Hex. So the working code has the start frame and the middle frame.

The unsuccessful learns are all device 21, OBC 46. As you noticed, the code is half length of the working one, and that's because only the start frame was learned. So I used IrMaster to render and export Pronto Hex for OBC 46:
0000 006B 000C 000D 004A 0025 0025 0025 0025 0025 0025 0013 0013 0013 0013 0025 0013 0013 0013 0013 0025 0025 0025 0025 0025 0025 0013 073D 004A 0025 0025 0025 0025 0025 0013 0013 0025 0013 0013 0025 0013 0013 0013 0013 0025 0025 0013 0013 0013 0013 0025 0025 0013 073D

I think you should be able to replicate this process for all buttons: learn the button, import into IRScope, put the resulting decode into IrMaster, and finally put the rendered Pronto Hex into USB-UIRT.

I'll be damned. It worked! That's exactly what I was looking for. I will attempt to do that on my own for the remaining 'trouble' buttons.

Thank you very much! I really appreciate it.

Hello,

I'm finally getting around to trying this myself for some buttons I need to learn but am having some difficulty. I've learned this code:

0000 006D 0000 000E 004C 0026 0026 0026 0026 0026 0013 0013 0026 0013 0013 0013 0013 0013 0013 0013 0013 0026 0026 0013 0013 0013 0013 0013 0013 0026 0013 073B

I can import it into IR Scope and save the .ict file and then import that into IrMaster, but I do not think I have IrMaster setup correctly as I cannot seem to get a working code generated. How do I get IrMaster to "render and export Pronto Hex for OBC 46"?

Thank you,
Mike

Nevermind. I got it. I had to take the IRP shows in IrMaster after importing the .ict file and create another 'Protocol' in IrpProtocols.ini. Once I did that and set 'D' to Device 21 and F (aka OBC) to 16 as shows in IR Scope, the Rendered code worked!

Thanks again for this awesome tip.

Mike

No, that's way too difficult.
After you've imported your learned hex into IRScope, go to IrMaster, choose Protocol as OrtekMCE, enter the device number (21) under D, and the OBC (16) under F. Then click Render. The contents of the text box is the desired clean Pronto Hex.

Or, if you want a whole range of OBCs, enter as above using the smallest OBC and then instead of clicking on Render, click on the Export tab. Enter the largest desired OBC there, and click on Export. That will write a text file for the entire range of OBCs.

You don't have to use IRScope at all, but if you have a group of learns, it is easier to see the patterns of function numbers, and may clue you in if a decode is spurious.

If you just have a single learn, you could paste it into IrMaster, and click Decode. Then use the decode information shown at the bottom and select the protocol, device, and function number as above, and click on Render. Make sure you enter in this information manually between the Decode and Render steps, or it will render the first protocol in the list with a 0 device and function number.

But that was the problem. I didn't have OrtekMCE as a protocol until I created it in that .ini file. I looked in both renderers. Perhaps there's a way to add a protocol within IrMaster that I missed?

All MCE remotes send toggle code's by default.

What are 'toggle' codes?

My old, official MCE remote sent completely different commands than this one. Additionally, the official remote sent two different codes for subsequent presses of the same button.

My current, new remote came with its own receiver as well and did not work with the official MCE receiver. So, two completely different remotes, me thinks.

You just answered your own question about toggle codes.  One code is sent on the first press of the button, and the second press sends a different code.

Regarding toggles, OrtekMCE doesn't use a toggle exactly. The actual IR protocol uses two bits to describe 3 states: 0 for the first frame, 1 for all intermediate frames, and 2 for the last frame. Pronto Hex is only capable of describing the first two states, but most equipment will still work with that.

I have no idea why OrtekMCE didn't show up in IrMaster. It is there in my copy, and I just downloaded it again--still there--IrpProtocols.ini Oct 2, 2011. The various protocols are listed alphabetically.
