JP1 Remotes

Hi all!

I've been combing these forums hopefully trying to get the answer myself, but I've come up frustrated.

I have a Comcast DVR 3-1 remote "Comcast_M1067A" model. I have successfully programmed it to work with my Denon AVR-1603 receiver (ancient technology I know) but it doesn't seem to properly send the Power on and off signals. I have deduced this is probably due to the Power On/Off being discrete for this device and non compatible.

I initially tried to setup a keymove where I made on just "Power" and off "Shift-power" but that didn't work.

I can successfully power on/off the receiver using the remote if I just select aux - setup - 5#EFC code. I know the code works, but it doesn't seem to work by key moving.

Any thoughts?

Have you tried to assign the two EFCs to some other buttons? Perhaps the power button doesn't accept keymoves.

Tell us which setup code and the two EFCs you're trying to use. Have you successfully programmed in any other EFCs? If so what are those?

I've tried assigning it to Shift-Power, Lock, and the PiP On-off buttons. None work.

I am using 1360 as the base code for the Denon.

The EFC codes were discovered on a different forum. They are:

01981 Power On
01917 Power Off

As I said, if I press setup and enter the code it performs the selected action for both on and off.

I have not been able to successfully program ANY EFCs at all actually.

Strangely, the 9-x-x codes for volume and channel locking both work. 9-8-1 did not solve the issue.

OK,
Let's try adding 65536 (2 raised to the 16th power) to each EFC.
On 67517
Off 67453

The 1067A Comcast remotes store EFCs in an unusual format. We know that 5 digit EFCs that start with 2 zeros don't work. Perhaps even one leading zero is a problem. First try the above EFCs with just setup-67xxx, and if that works, try assigning to a button.

Odd.

The codes work when using the "setup-code" method but again, when attempting to store, they just don't work.

This is the method I'm using. Maybe I've got the routine wrong.

Press AUX
Press and hold SETUP until AUX flashes twice
Type 9-9-4
Press setup
Press 67517
Press power (AUX flashes twice)

Isn't this right?

Also, thanks for being so helpful even if it's still not working.

Well, let's try a different tack. The Denon protocol only uses 5 bits of device data, leaving 3 bits unused. The Denon Combo executor uses one of those 3 bits to control whether the protocol type is Denon or Sharp, but I suspect that the other two bits are ignored. So we can void the leading zero by setting one of those bits.

Please try:
ON 65469
OFF 65405

No luck. These new codes do not work when tried directly (setup-code) or when stored.

I've also tried mapping the 67-xxx codes that do work to buttons I know function. For example, I know the mute key works as programmed. I tried storing the 67453 code to Mute and it still mutes the device--essentially it's as if the codes are refusing to be stored.

Is it possible that the 9-9-4 method has been disabled on this remote?

In general, keymoves do work on the 1067A. I don't know how one would disable them.

Would you mind trying ON-06077 and Off-06013 to see if setup-code works with those?

No luck. I'm really wondering if I'm just doing something wrong. The first 67-xxx bank of codes are the only that worked.

Edit: Also, when trying the 9-8-0, 9-8-1, and the 9-8-2 codes to return the remote to default settings, nothing changes. All programmed devices are still controllable including TV and the cable box.

How about just trying to assign up arrow 34047 to the mute button? That would completely eliminate the issue with leading zeros.

To unassign a button do 994 followed by tapping the button to unassigned twice.

No change.

When doing setup-code it works as an up arrow command. When attempting to program the button still works as mute.

When unassigning the button, the AUX button flashes twice to indicate it has worked. Then when assigning the button later, it again flashes, but pressing the button still works as mute.

Maybe mine is defective? Smile

Maybe so. Where I live, Comcast will exchange a remote pretty much no questions asked. If you do try to exhange it, see if you can get a red OK/Select button version (1067B). It has more setup codes, and doesn't suffer from the leading zero problem.

Thanks for all the troubleshooting help.

I was actually planning on swapping out my DVR for a regular box. I'm cheap and I use an HTPC for all the TV I watch anyway.

This whole endeavor is really just so my wife can stop asking me why we have to have three remotes when she wants to watch Food Network.

So sassafras, what that means is that if you want to program this remote to work the way that you want it to work, you'll need a JP1 cable. Of course, you could also swap it for a newer model with Comcast and the newer model will most likely support keymoves.
