comcast dvr remote reprogramming fundamentals

12758 Views 15 Replies 7 Participants Last post by  3FingeredGlove
I found the following instructions for key remapping with my comcast remote here:

http://en.wikibooks.org/wiki/How_to_...ing_the_Remote


If I understand correctly, assuming I know the the code for a command that I want to program (a number from 00000 to 00255), I should be able to program the remote to send the command. However, I am a little unclear on the instructions. They are copied here below with my comments in .


---------------------------------------------------------------


Remap a Key


This is the general procedure for remapping. Several common mapping options specific to the Motorola DVR are listed below.


1. (Option) Press and release the device key to make it the default.




2. Press and hold the "Setup" button until a device key blinks twice.

3. Type in the code 994. A device key will blink twice.

4. (Option) Press and release the device key for the source device.




5. Press the key to get the code from. This can be:

1. Another button with an existing code

2. Press and release "Setup", then type in a 3- or 5-digit code. The code is called an 'Extended Function Code' (EFC). Most of the silver remotes use 5-digit codes. Most others use 3-digits. In most cases, you just add '00' to the front of the 3-digit code to get a 5-digit code (00173 = 173).




6. (Option) Press and release the device key for the destination device.




7. (Option) Press and release "Setup" to create a shifted key.

8. Press and release the button you want to put the code on.




9. If the remap is successful, a device key will blink twice.


In general, I think it would help my understanding to learn more of the fundamentals of how these protocols work, but I have yet to find a resource on the web that lays this out.

Default here just means being in the mode to control the device, as in "CABLE", "TV", or "AUX"

These steps are for what UEI refers to as Keymoves. You are moving a functions defined in one key in a mode (the source), to another key in another mode (the destination). For example, you can move a function like ASPECT from the TV mode to a key (like the "HD/ZOOM") key in CABLE mode so that you can press the "HD/ZOOM" in CABLE mode to access the function on the TV without having to change to TV mode first. You can also use the keymove functions to add new functions if you know the EFC of the function. In that case, usually (not always), the source and the destination mode will be the same, and you can skip those steps.

No, there is a device ID along with the ir protocol that each device uses, but that's part of the setup code, so if two devices uses the same setup code, that means they both have the same ir protocol and device ID. Some devices can be changed to use a different set of codes, but most likely, the Comcast remote only has the primary set. There is a way to add upgrades to the Comcast remote; more on that later.

See above on source. The destination is the mode you want to move the function from the source to.

There's actually two issues here. One is that if you found a setup code for your TV which has some of the functions, but not all, there is a way to add additional functions using EFC.


The second issue is that by default, the Channel lock function and the Volume lock functions are turned on with these remote. Channel lock sets the remote to alway use the functions of the CABLE mode for channel up and down, the number keys, and couple of other keys, no matter what mode you were on when you press those keys. Volume lock is the same for the volume up and down and the mute key, except it is set to TV mode by default. You can turn that off, or change the mode it should be set to (for example AUX for volume if you have AV receiver set to AUX).

A better resource for learning about reprogramming the Comcast remote, and other remotes made by UEI is here:
http://www.hifi-remote.com

Check out the forum for more info. You can also find there, a way to make (or buy) a cable to connect the remote to a PC to reprogram key maps easier, add upgrades to control devices not built in, and add new functions. The Comcast remote is what is referred to in that site as either JP1.2 or JP1.3 remote, depending on how new yours is.

In all the years I've had a Motorola DVR, I didn't know the silver remote was made by UEI.
So instead of programming the remote that came with the DVR, I bought a UEI 6131 and programmed that instead! Oh well, the Comcast remote only controls 3 devices anyway.

I have been searching for a while on this...


This is exactly what I want to do for mine - I have a Sharp LC46D64U, whoose remote has a key on it for View Mode that cycles through 4 options. How can I re-map this function to the ZOOM key on the Comcast silver remote?

Assuming you are using setup code TV/0093 for controlling the TV with the Comcast remote, try this:

1 Press and release TV

2 Press and hold SETUP until the remote blinks twice

3 Type 9 9 4

4 Press and release SETUP

5 Type 0 0 2 3 4

6 Press and release CABLE

7 Press and release HD/ZOOM


The remote should blink twice. If you are using a diffeent setup code, post what it is. The advanced code in step 5 might be different.

Works perfectly - Where did you find that sharp code? I looked for days - nothing here:

You are good at this! Thanks so much!
Hi there,


I'm trying to remap a remote from a Motorola DCH3416 that was originally supplied by Comcast.

I'm using the box with a cablecard supplied by RCN.

Most of the keys work fine, but there is an issue with the triangle (A), circle (B), and square (C).

When setting up a recording, these buttons are used to final or cancel a selection.

Their respective purposes are called out by shape and letter.

The problem is, they don't seem to do anything in this menu.

What's odd is that their secondary use (jumping forward and back days in the guide) is functional.

I've looked over the sites linked above, but I'm still not sure how to solve my problem.

Am I barking up the wrong tree?

Would anyone mind lending me a hand?


The ID of the remote is RC1475505/02MB


I'd be very grateful for any help as this is preventing me entirely from recording any show I'm not currently watching.


Cheers All

Alex

The remote doesn't know which menu you're in, so the buttons always send the same IR signal, assuming you don't change the remote to TV or AUX mode.


So I guess the problem is either in the box, or in your expectations of the way it should work.


We have a DCH3416, used with Comcast cable service, and we have never used the A, B, or C buttons. Recordings are set up through Comcast menus accessed by the My DVR button. Navigation is done with the arrow buttons.


However, over time, there has been some variation in the signals sent by A, B, and C.


Our red button Comcst remote sends the following EFCs: A == 00081, B == 00174, C == 00178. But Comcast has provided an upgrade which changes the EFC associated with A. Without the upgrade, the remote sends A == 00083.

Older Motorola remotes send A == 00077, B == 00237, and C == 00114.


You may want to try these EFCs to see if that provides a desireable result.


You can test an EFC by tapping Setup and then entering the 5 digit EFC. When you press the 5th digit, the IR command is sent. If you like the result, use the 994 command to semi-permanently assign the EFC to the button.


See the 9XX instructions.

Just installed a Samsung LCD TV, a Comcast 3416 HDDVR, and a Samsung HT-C6600 3D-blu ray-based HTIB for my sister. Everything works great, and I entered the LCD TV setup code on the red-OK button Comcast remote and it controls TV volume and on/off just fine.


The HTIB is set to block the sound signal to the TV, so I tried to enter the AUX button code to allow the remote to control on/off and volume for the HTIB. I tried the 10 codes listed for DVD players and DVD-R players, but they don't work. Several codes blinked the AUX key twice like they were the one, but they weren't. I tried Searching for the code, but wasn't sure on steps 2-4 if I was supposed to press AUX/Setup, wait for 2 blinks, then press 991 or 992, then a 2, then Power only once (?), followed by repeated CH+ . I actually think I forgot the lone 2, but by then I was going nuts. Called Comcast and they gave me a 5 digit number beginning with a 3.... didn't work.


Can someone please help me with a code for the AUX button to allow the remote to just do on/off and volume for the blu-ray HTIB ? Or the exact process to Search for a code? I must be doing something wrong because there are probably thousands of these HTIBs out there and no one else is asking for help. Thanks.


PS: We don't need arrow, pause, stop, etc. because the HDDVR is connected into the blu ray via HDMI and 99% of the time they'll be watching TV, not blu rays. So they just need the AUX button to allow the All On button to power on/off the HTIB, and the Volume toggle to control the HTIB volume. Hmmm... that's probably a problem isn't it? Which volume, TV or HTIB.

I don't know about the HT-C6600 but Samsung HTIB systems generally use IR protocol NECx2, device 67.83.


Unfortunately, Comcast remotes don't have any setup codes that send this IR protocol.

Thanks for your help, I can relax knowing for sure that it won't work. But, two last questions.


Since it doesn't have a receiver, but is a blu-ray player with 2 HDMI inputs and 6 speakers, is it possible that a Samsung blu ray code could work; at least to turn it on/off with the All On button? Are there Samsung blu ray codes different from DVD codes listed on Comcast's sheet? Thanks again.
So far as I know, all Samsung Blu-Ray players respond to setup code 20199.


Again, I don't know specifically about the HT-C6600, but most Samsung HT systems use setup code Audio 1295 (31295 in remotes which take 5 digit codes). These setup code refer to remotes made by UEI.


One simple approach is to buy a RCA RCRP05B for $20. Walgreens, Best Buy, and on-line. A OneFOrAll URC-8820N will also work, but isn't IMO laid out as well for Comcast and Blu-Ray players. Sears.

20199 is in the Comcast list for DVD players, so I'm sure I tried it, but I'll give it another try. When I called Comcast, they gave me a number beginning with 3, but I left it at my sister's, so I'll also try 31295. Unfortunately, I won't be going out there for a few weeks. I'll let you know what happens. Thanks for all your help.


PS: I thought about your earlier statement that this remote doesn't control Samsung HTIBs. My thinking was that this unit is a blu ray player with HDMI inputs added, but it's more likely a receiver with a blu ray player added.
Guess I wasn't clear. Comcast remotes don't have 31295. If you type that in, the remote will give one long blink instead of two short blinks, meaning the setup code wasn't recognized. If it had 31295, I would have pointed you at that in the beginning. The remotes I listed above do have 31295 (or Audio 1295). If those seem too expensive, see if your local Radio Shack has this one , or its siblings the 15-133 or 15-135. Those remotes have 31295. Can't beat one dollar......
Yes, I did miss that it was for the other UEI remotes. I don't want to take up much more of your time, so just a final question. Can the Comcast special buttons (like MY DVR, Guide, etc.) be mapped into the remotes you mention, or would a more expensive remote like a Harmony be needed?


And a final final question. How could I best learn about programming remotes... is there a website, etc.? Thanks for all your help.
Yes, you can assign functions to buttons manually. Universal remotes don't usually have buttons labeled with every function name. For example, universals don't have a button labeled MyDVR, but you can assign a code to most of the buttons which will send the IR signal that does the MyDVR function.


If you buy one of these, I'll tell you how to make the assignments of the specialty functions.


The website which has lots of experts on UEI (more typically referred to as JP1) remotes is http://www.hifi-remote.com/forums/ .
