I'm trying to integrate functions from an old Harman Kardon AVR-55 receiver into a Comcast-branded OneForAll URC-1068 remote control. All of the basic functions work fine using device code 0110, but there are a couple that I can't seem to hack out. I ran through all 256 protocols for device 110 (setup + 0 + 0 + 3-digit code), and found the functions I needed which were unlisted / labeled differently in the standard advanced code databases. Those are:


303 video 1 (referred to as vcr1)

307 video 2 (not listed at all)

621 dvd (referred to as VDP... video disc player? maybe?)


The problem is that I need to have control over 2 keys which are very important to my setup: "Dolby Digital" and "Dolby Pro Logic". None of device code 0110's 256 protocols do the trick. The only other Harman Kardon device code listed for this remote is 0189, which seems to do nothing.


Finally, the question - does anyone know where I might find the advanced key codes for these functions, or some method of figuring them out?

It looks like those keys are usings a different device code that the URC-1068 doesn't quite have. There might be a way to upgrade the remote with the correct protocol if you have a JP1.2 cable (I've upgraded my URC-1067 with MCE protocol to control my HTPC). You can learn about adding upgradeability to the remote starting from here . Those pages is mostly about JP1 cables, but the Comcast remote would need a JP1.2 cable. The software and the procedure are the same, but the cable is different.


If you are going to go the JP1.2 route, there are some upgrade files for HK receivers here . While none currently is an exact match for your receiver, probably one of those will work (the files for AVR-30 and AVR-330 has the most keys included). You can also see from those files that the functions you have currently working with 0110 code are the ones listed as "128.112" under "Device" and there are other function listed as "130.114", which are the functions you can't program currently.

Thanks so much! Upon searching for plans for a 1.2 cable, I've decided to go with the pre-built solution. I found one for $17.49 at diygadget.c*m/store/jp1/jp1-x-for-remote-controls/jp1-2-serial-cable/prod_25.html


After many hours of hacking out unlisted advanced code protocols, I managed to squeeze 5 devices into the Comcast 3-device remote, but I think I've gone as far as I can using that method. Now that I know jp1 will allow me to make backups as well, I'm definitely ready to take the JP1 leap. Thanks again!

I got my cable and got the remote (turns out it IS a URC-1067) working with IR to the point that I can at least back it up and do basic stuff with it. I'm still having no luck getting the missing functions for the Harman Kardon to work, though. The "HK Combo" protocol which is associated with most of the Harman Kardon receivers isn't compatible with the URC-1067, for some reason. I get "The selected protocol "HK Combo (01 41) is not compatible with the selected remote...." from rm 1.74 - just NullException errors from previous versions.


After doing some research on HK receiver models, I found that the AVR-85 and the AVR-500 were manufactured around the same time, and are most likely the closest match in the JP1 Files section. I've confirmed from looking at these and several other upgrade files that the functions I'm looking for are almost certainly in device 130.114.


Running decodeCCF on a Pronto file for the AVR-85 (and several others) revealed a little more information - not only Device 130 and SubDev 114, but they show the Protocol for those keys as being "NEC2".


I tried upgrading the 1067 with the NEC2 protocol - no go on the receiver recognizing anything.


Before I give up, can someone tell me how to translate device.subdevice into an actual protocol? I can't seem to find this information listed anywhere. All I need is a couple of functions from 130.114.

Try using NEC 4dev Combo protocol, or see if the attached RMDU file works.

Well, I'm 1 step closer. While none of the pre-defined functions in that protocol did the trick, EFC 101 did the trick for selecting AC-3 mode. I determined this by running through setup+0+0+x+x+x for 000 - 255.


According to the CCF file I found for the AVR55, 101 is in fact the EFC for the AC-3 mode. 002 should be the last one I'm missing, Dolby Pro Logic. Unfortunately, 002 doesn't transmit that code with the protocol you provided. Running decodeCCF doesn't provide any hex data, or I'd probably be set. All it gives is protocol(NEC2), device (130), subdev (114), efc (002), obc (159), and top freq (36.3609). I'm pretty sure that's the one I'm looking for.


I'm not concerned with having the rest of the functions for the tuner in the protocol - I just want the 2 keys. I already have 5 devices squeezed into a 3-device remote by assigning a device to aux, doing the hold_setup+994+dev1+setup+00efc+dev2+key trick. (since moved keys retain the codes even when aux is reassigned to a new device)


Is it possible to just get the upgrade protocol for 130.114 in full?


BTW, thanks a ton for your help!

I've create a simple file with NEC 130.114 and just the AC-3 and Dolby Pro functions. Since you said you only need two functions in device 130.114, I've changed the protocol to simple NEC (which HK protocol apparently is), instead of the 2 device combo. I've tested by capturing the signal using this and I get the correct OBC (159) and device. See if that works. BTW try posting at the JP1 forum any problems or questions. There are a lot more knowledgeable people there. Also post your IR file at the diagnosis area and post the link to the file there and people can look over your set up to see if there's any problems there or maybe ways to save memory.

That did the trick! I officially now need only 1 remote instead of 5. Before I did some random Googling on the Comcast remote, I was certain I was going to have to fork out at least $200 for a universal remote. As it turns out (and thanks to you) I only paid $18 for a JP1 cable and have what is probably a better-working, friendlier remote than had I gone the other route.


Thanks again!
