Comcast DTA (DC50X) decodes?

greenough1 · Post by **greenough1** » Thu Mar 12, 2009 9:20 am

1. Device: Comcast DTA (digital transport adapter)
2. Type of device: Encrypted cable decoder
3. Year: 2009
4. JP1/UEI Remote model: UEI 3067BC1-R
5. Do you have a JP1 cable? yes
6. Still have original remote? yes
7. Checked the file section? yes
8. Checked Pronto file section (at R/C)? no
9. Partially working setup code? no
10. Learning remote question? yes

I just received a DTA from comcast for my TV's to deal with the fact that they are going to encrypt the expanded digital channels in my area soon. This decoder un-encrpyts them and passes the analog signal to my TV.

The remote for the device is the model number given in 4. above. I tried to learn the signals to my 8910 and got
this FILE . It's clear some of the learns were bad, but I need some help with the Dreambox decodes

What would be a good starting setup code? Why didn't I get more info from IR regarding the learns (I have IR 7.06) on this computer.

Best,
jeff

Didn't you have an IR file in your original post?

Sorry my cut and paste didn't bring the link over... link fixed now.

Try this file for the CISCO RNG200

Thanks Rob. I'll work on it tonight.

Is this decode sort of normal for this protocol?

Yes. XMP is a horrible protocol that has 16 different burst pairs (0 thru F) and UEI learning remotes have a really hard time telling the difference between an E and F pair. DecodeIR does the best it can and converts the signals into hex. I just happened to recognize the hex as matching the Cisco, which I had decoded recently. I compared the limited buttons that you included and they all matched the Cisco buttons.

Lucky for me this was fresh in your mind - thanks again.

I'll put the upgrade in the files area when it's built.

I'll post a picture of the remote tonight. It's sort of cute, and allegedly can control a TV in addition to the DTA. It is made by UEI, but there's no readily accessible header.

Best,
jeff

Rob,
I tried the upgrade and the ch+, ch- work as well as the number 8 and 9. All other buttons do not work. All that matter to me are the number keys and the channel.

What's the strategy for guessing the EFC's for the number buttons?

Thanks,
jeff

Is it the case that if I add the above upgrade to IR and then learn from the DTA remote, IR can then decode the signals and give me EFC's?

The upgrades installed in a remote have no influence on how IR decodes learned signals, or that matter how the remotes learns signals.

As for guessing button codes, the only idea that might be useful is that the OBCs for digits are usually contiguous. Sometime 0 is before 1, sometimes 0 is after 9.

Don't bother looking for different OBCs or EFCs as the right ones are in the file, so I don't know why the complete upgrade doesn't work for you.

*** I'm a dope ***

I went back and drag-and-dropped the keys onto the remote layout and it worked with the new version of RM. All is good. Thanks Rob for the upgrade.

Thanks again,
jeff

So the only buttons that worked were the ones that you actually assigned to buttons!

You dork!

Final upgrade uploaded. Thanks again Rob.
