Has anyone been able to capture the IR codes for the Motorola DCX3400 used by Comcast? I can not find the codes for "My DVR" and "Swap" buttons for my Pronto. The Pronto (for some reason) can not learn the codes from the Motorola system, everything else seems to work.

Try these,

MY DVR
0000 006C 0012 0002 0153 00A9 0013 00A9 0013 0054 0013 00A9 0013 00A9 0013 00A9 0013 00A9 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0468 0153 0054 0013 0D13

SWAP
0000 006C 0012 0002 0153 00A9 0013 00A9 0013 00A9 0013 0054 0013 0054 0013 0054 0013 00A9 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 00A9 0013 00A9 0013 0054 0013 00A9 0013 0468 0153 0054 0013 0D13

If they don`t work, Post the your Learnt Hex Codes for these even if they don`t work.


Cheers

Jason, that was very helpful, thanks. For some reason, the learnt IR code for SWAP simply didn't work... but your code does.

Now I need to find the code for On Demand and I'll be all set.

Thanks again!

Try this :
On Demand: Device Code: 0 Function: 26
0000 006C 0012 0002 0153 00A9 0013 0054 0013 00A9 0013 0054 0013 00A9 0013 00A9 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 00A9 0013 0054 0013 00A9 0013 0054 0013 0468 0153 0054 0013 0D13

The DCX3400 actually responds to two different IR protocols-- General Instruments device 0, and XMP device 62.16.

The Comcast supplied remote sends the XMP protocol (setup code 01982) which can be quite difficult to learn. Jason provided the GI IR protocol, and the Pronto Hex above is also GI.

If you want to exactly duplicate the IR protocol being sent by the Comcast remote, I can provide those Pronto Hex codes. I'm not aware of any particular reason to use XMP rather than GI.

The XMP codes are in this Thread, Post 11 and 16 if you want them.

3FG - I would appreciate any more of the pronto hex codes. The three on this page seem to work perfectly for my DCX 3400. The ones referenced in the other thread post 11 and 16 do not work at all.

Start with these codes, and then post if some are missing.

I've been searching up and down the web looking for the "skip" or "advance" code. I've enabled the 30 second skip on the Comcast Tivo DCX3400 and it works from the Comcast Tivo remote, but I can't get it to work on my remote that I'm programming

So does - anybody have the code for Skip (also known as Advance) or the "->|" key??

Wow. Thanks for the quick response ... and it works!

Where are you getting the function codes and doing your hex generation from?

Do you also have the XMP codes? I have the spreadsheet for generating the XMP hex.

We already know that the DCX3400 reesponds to the traditional GI Cable IR protocol or to the XMP protocol. I don't know if a 30 second skip is implemented under XMP, so I gave you the Pronto Hex for the GI Cable protocol. Both sets of data are available at hifi-remote.com in the Cable section.  Basically the XMP stuff comes from the CBl 1982 setup code in Comcast remotes, and it applies to a variety of STBs.

I use MakeHex with the MakeHex GUI.  Jason wrote a pretty good explanation of how to use them, although not for XMP.  Use IRTool to check if your Pronto Hex is correct.

Does anyone have the reverse skip code (~15 seconds backward)?

Both of these should work:

Replay GI Cable Device Code: 0 Function: 60
0000 006C 0012 0002 0153 00A9 0013 0054 0013 0054 0013 00A9 0013 00A9 0013 00A9 0013 00A9 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 0054 0013 00A9 0013 0054 0013 0054 0013 0054 0013 0468 0153 0054 0013 0D13

Replay XMP Device Code: 62.16 Function: 83
0000 006D 0012 0012 0008 0022 0008 0041 0008 001D 0008 006A 0008 0032 0008 0032 0008 002C 0008 0065 0008 020D 0008 0022 0008 0041 0008 001D 0008 001D 0008 0037 0008 002C 0008 001D 0008 001D 0008 0BF2 0008 0022 0008 0041 0008 001D 0008 006A 0008 0032 0008 0032 0008 002C 0008 0065 0008 020D 0008 0022 0008 006A 0008 0046 0008 001D 0008 0037 0008 002C 0008 001D 0008 001D 0008 0BF2

Edited to fix wrong function numbers.

I tested both of those, and neither worked. Any others?

My mistake. I gave you the Pronto Hex for UEI's EFC convention rather than the function numbers. I've edited my post above with, I hope, the correct codes.
