Kenwood KR-V7040

Post by DiscoRage »

1. Device: Kenwood KR-V7040
2. Type of device: Audio receiver
3. Year: 91 or 92
4. JP1/UEI Remote model: Rogers OCAP DVR (1056) and Rogers DVR (1055) - both JP1.3
5. Do you have a JP1 cable? No
6. Still have original remote? Yes, but I don't have access to it right now.
7. Checked the file section? Yes
8. Checked Pronto file section (at R/C)? Yes
9. Partially working setup code? No
10. Learning remote question? No

I've tried all Kenwood codes from the manuals for both remotes. I've tried other Kenwood codes I've found on this website. I've tried code search but got fed up after 10 minutes with no results.

I don't know if this will help, but here is a link to the manual for this receiver: http://www.scribd.com/doc/3279822/Manua ... al-English

This file, from the file section:
http://www.hifi-remote.com/forums/dload ... ile_id=432

indicates that device uses NEC1, device 184

The only built in codes I can see for your remotes that might work are all listed in devices.xls as using NEC combo(official) -
Audio 1313
Audio 1569
Audio 1570

If those codes control anything on your device at all you might be able to use keymoves from the functions listed in the upgrade I linked to get a working setup.

(It could also be that I haven't searched properly - so if anyone can see a built in code I'm missing, please jump in !!)

This page: http://www.urcsupport.com/html.php?page_id=518 seems to indicate your Rogers OCAP DVR (1056) might be a learning remote, though - are you sure it isn't (ie have you tried learning on it) - just because it's not in the manual doesn't mean it won't work.

If it is a learning remote and you can "get access" to the original remote - that could be a solution.

Failing all that, you might need to think about getting a cable to load an upgrade - that's what I'd recommend anyway - it makes it all much easier, and you have total control of your remote.

In the File Section, under Audio upgrades, is an upgrade file for the KR-V7040. That's most easily used if you have a JP1.3 cable, but if you're willing to enter numbers into either of your Atlas remotes you can program the remotes by assigning an EFC to a button for each function.
Here's a list of the EFCs.

Code: Select all

Function      EFC
0	57915
1	58043
2	57979
3	58107
4	57883
5	58011
6	57947
7	58075
8	57899
9	58027
vol up	58083
vol down	57955
mute	57859
channel up	58019
channel down	57867
power	57987
Tuner Band	58059
Phono	57907
Video 1	57939
Video 2	58099
CD	57971
Tape 1	57875
Tape 2	58003
Tuner	58035
To assign any one of these to a particular button, first assign setup code Audio 1313 to a device button (like AUD). 1313 actually sends the NEC1 IR protocol, with device 184.0. The Kenwood wants 184.71, and your Atlas remotes are too new to still carry a setup code for that. But you can override the built in device number:

To make Vol+ work,
1) Press Setup until 2 blinks
2) Enter 994 (2 blinks)
3) Press Setup briefly
4) Enter 58083 (taken from the above list)
5) Press Vol +
The remote should now blink twice.

Repeat this procedure for each function and button that you want to assign.

Yes - I spotted

Audio 1313
Audio 1569
Audio 1570

in devices.xls (listed as NEC Combo - dev 184) while you were posting, and edited my post

Jim,
Have you tried Vicky's Lookup Tool (link at the top of the page)? I find it to be much easier to use than devices.xls, and it carries EFC information also.
The EFC information (which is mostly accurate) allowed me to rapidly see that setup code 1313 is shooting 184.0, by typing the 5 digit EFC into RM. It also showed that 1313, 1569, and 1570 are basically the same-- Vol+/- have the same EFC for all three setup codes. So it is clear that none of them will work without modification for the Kenwood.

I have used Vicky's tool - it's great - but I'm an Excel user so I like to do it by filtering the columns in devices.xls

That's why I missed those built-ins the first time - I filtered for NEC1 - and they were NEC1 Combo(official). Stupid - I should have just filtered the device number, like I usually do.

I noticed the built in codes use 184.0 - but so does the upgrade I found - I linked it above.

I don't have any knowledge of this Amp - so if it really needs 184.71 then you are obviously correct.

Ah - I see now - looking at the 5 digit EFCs in KM and the b2/oc = 71

Um....
No, the linked file shows NEC1 device 184 without a subdevice. But that doesn't mean the subdevice is 0!

Actually NEC1 protocol always sends 16 bits of device information. Originally, the second 8 bits were just the complement of the first 8 bits, so only a device (and no subdevice) could be independently specified. That's a kind of error detection. Later companies began to use the first and second bytes independently (breaking the complement rule) and that yields a device.subdevice pair. However, if a subdevice isn't listed then that means the original rule is being followed, and the subdevice is implied to be the complement of the device. So 255-184=71 and that's the actual subdevice used by the Kenwood.

BTW, I did try the procedure I outlined for DiscoRage above, taught the resulting signal to a different remote, and then had IR tell me what the remote was shooting. The answer is NEC1 device 184 with no subdevice listed.

Yep - I got it (in the end) by looking in KM at b2/oc and the 5 digit EFCs - changing protocol to the NEC1 combo (official).

I'd seen that byte2 as complement of byte 1 before and forgotten it :oops:

Forgive me, I've had a few drinks with the roomies tonight, so I might not me as coherent as I usually am. But I have tried all of those codes and none of them work. Not a thing. No volume, no power.

They are learning remotes, but because I don't have the receivers original remote handy, I can't do any teaching. I suppose I could get my dad to mail it to me.

At this point, I'm not interested in getting a cable. I'm only using this receiver as a temporary fix since someone spilled a can of Coke Zero in my Yamaha RX-V800. I plan on buying a new receiver soon.

Dudes, thank you for all the info. I'll give everything a shot tomorrow when I'm actually sober. I gotta go watch T2.

I think what will work is if you follow 3FGs instructions from above for entering manual keymoves: http://www.hifi-remote.com/forums/viewt ... 6207#86207

I just confused the issue by missing that you will need to use those 5 digit EFC numbers to make the built in codes work.

Just follow those instructions and ignore what I said and hopefully you'll be all set

Enjoy T2 :)

It worked! You magnificent bastard, it worked! I'm going to try programming in all of the codes. Being able to change the input would be great. I will have some follow up questions.

Wow, thanks. Everything is working perfectly. The only thing I couldn't get to work was turning the power on and off with the power button. I have it assigned to the FAV button right now, and I'm fine with that.

This remote only has a master power key. The manual has instructions for programming it to turn devices on sequentially in CBL mode. By default it turns on the cable box and then the TV. I'm fine with this, but when in AUD mode, I can't assigned the power key to turn my Kenwood off. Can you think of any workarounds?

Also, are there additional ECF codes for NEC 184? In AUD mode, the number keys and channel -/+ only changes channels that are pre-programmed into the tuner. What I'd like to be able to do is use channel -/+ to scan, and the number keys to manually enter frequencies.

If I understand you correctly, you have been able to assign Power to the Fav key, but not to the Master Power key, and you want to be able to control the Kenwood power independently of the rest of your equipment.

Why not try to assign the power function to the shifted Power button? To do that, insert a brief press of Setup between steps 4 and 5 above. If this assignment works, you can turn the Kenwood power on/off by the comination of two keypresses-- first Setup, then Power.

Regardigng other EFCs, there are 256 possible EFCs with the NEC1 protocol, and you could try them all. But I'll be very surprised if you can enter arbitrary frequencies.

You know what, I'm fine with using the the FAV key to turn the Kenwood on and off. I'm off all day tomorrow with nothing to do, so where can I find a list of all the ECFs for NEC1?
