Hello,

I don't know if this is the right place for this post, but I'm getting desperate. I am one of the many new victims of Comcast's switch to All Digital. Because of the switch, I now have to use a Digital Transport Adapter in order to convert the digital signal back to an analog signal. The problem is that I use a home built PVR (running MythTV), and it needs to be able to change the channels on the DTA. I also have a regular Comcast set-top-box (Motorola brand) which is also connected to my PVR. I have been controling it just fine for quite a while now using LIRC and an IR-Blaster. When I got the new DTA (Pace dc50x), I picked up a dual-head IR-Blaster, but can't find a LIRC setup for the remote control. There is ZERO information on Pace's website, they don't even list the dc50x as one of their products. From other forums it seems the remote uses the xmp ir protocol, but that's about all I can find. Please, if anyone knows where to find or how to make a LIRC remote control setup file for this box, please let me know.

Thanks

don't know if this is helpful, but I was having problems getting my URC-8811 to work with this box and it turns out that it needed a new code and a new protocol uploaded to the remote to work. So, I am assuming the yours needs the same. Here is a link to the file I downloaded. It is a text file that contains all the information for the code and the protocol:

[Link: hifi-remote.com]

Maybe you can extract the information you need from the file!

Hope this helps and good luck!

lilogre2357, have you made any progress on this? I'm trying to solve the same problem and I am also running mythtv & LIRC. I was unable to get the IR blaster that comes with the Hauppauge PVR-150 to control the DC50X after trying the 700+ known codes. I've submitted a ticket to Hauppauge to see if they can help.

Which IR transceiver are you using? My guess is that you should be able to "teach" your system the codes by using "irrecord".

I email'ed the support folks at Pace and received a very helpful response. In a nuthshell he referenced the XMP protocol and indicated that the IR blaster sold at [Link: usbuirt.com] is compatible with the DC50X. The forums at [Link: usbuirt.com] contain information on getting it to work with mythtv / LIRC. I'm not pursuing this yet as the IR blaster he suggested costs more than I wanted to spend ($50).

I am another one of the victims of the impending Comcast switch to digital. After many trials and tribulations, I was finally able to get a DC50X box to work with my MythTV setup. I'm using a RS232 IR Blaster ($12 from www.irblaster.info) to control the DC50X. I thought I would post some the details here to help others in the same predicament.

I was able to generate a CCF file for the remote by using several of the tools from Remote Central. I first learned the IR code for the Power button with my TS1000 remote well enough to paste the results into IRTool with DecodeIR DLL and decode them. This showed that the protocol is XMP and the device is 62.16. I then used MakeHex to generate all the proper codes for this device. For each key on the remote, I just had to learn it well enough to decode the function code, and then look up the proper full code in the MakeHex output file. This code was then pasted back into ProntoEdit to generate the CCF file. I have posted this CCF file to Remote Central if anyone is interested.

The next step was to convert the CCF file to a lircd.conf file for use with MythTV. For this I used CCFDecompiler from CCF Tools to convert the .ccf file to an XML file. Then, the pronto2lirc.py script from lirc.org was used to convert the xml file to a lircd.conf file.

Here is my final lircd.conf file. I didn't include all the remote keys in this file because only the numbers and the 'Enter' key are used to change channels on the DC50X.

silliman, thanks for posting that -- its a great help! It winds up that Comcast has made the expanded basic channels available "in the clear", so I can tune them in with my clear-QAM digital tuner. Having said this, there is the risk that they could decide to re-encrypt them, at which point this will be very useful. Thanks again for taking the time to figure this out and posting your results!

Silliman, thank you tremendously for figuring this out. The .conf file worked perfectly for me.

Thanks for this! I'm not having much success with the RS232 IR Blaster (from irblaster.info), though. This configuration works, but the transmission is iffy; a sent code actually affects the Pace DTA only one time in 10.

I have the blaster right over the Pace's IR receiver, and I've tried moving it around and different angles. I've tried different Transmitter settings, but only the defaults work. Nothing helps. (BTW, I'm using WinLIRC on Win XP.)

Far as I can tell, that transmitter is simply underpowered, not putting out enough IR light. Anyone else having the same problems? Or NOT having these problems with the same device?

I tried Mike's remote config, but this is the only output I get from irsend LIST "" ""

irsend: DC50X

Any ideas? Thanks!

Ok, so I was a little mistaken. I thought that it should list all remotes and codes. irsend LIST DC50X "" shows all of the codes and if I send any of them, the LED on my blaster lights up, but the box doesn't do anything. I just got it last month, is it possible they are using different codes for the newer DC50X's now?

I think there is no chance that the DTA codes have changed. That would be a nightmare for Comcast, and there is no reason for them to do it.

If you want to check anyway, and have a silver Comcast remote with a red OK/Select button, you could temporarily change to setup code Cable 1982. That sends the XMP protocol that the DTA uses.   Then change back to 0476 or 1376 to control the normal set top box.

You have to unlock the cable setup code, using the 982 command, in order to change the setup code for cable mode.

Thanks 3FG,

I just picked up a RCA RCRP05B, universal remote.
Took 2 1/2 fighting and searching forums for codes that might work.
your code 1982 finall did it.

1982 seems to work, thanks again.
