"No response from interface" with URC-7562:tried e

[carlosp_uk]

Hi there

So, I took the plunge and bought a JP1 cable, which I'm trying to use with my URC-7562, but sadly I haven't been able to get it to work, I constantly get "No response from interface" whatever I do.

I have followed the troubleshooting steps in Tommy's Rev5 document (TransmissionDelay, Interface Test, etc.) and have tried all available different battery combinations. I took apart the cable to check it was sound too - it appears to have pins 18-25 soldered together (it's a PCB one from diygadget) so I can eliminate a grounding problem.

I have one potential clue :

If I click 'Download from Remote' in IR.exe WITH the cable plugged into the remote then I get "No response from interface".

BUT...

If I click 'Download from Remote' in IR.exe WITHOUT the cable plugged into the remote then I get a different error: "Did not receive a response......." (ErrNo=7, Param=160)"


.........this is driving me crazy! I'd really appreciate any help that you guys can give to me. Otherwise it's back to looking for a way to patch the signature of (IR2)WAV files...

UPDATE: If I connect the cable one way around to the remote, all of the device lights illuminate permanently and it reboots upon disconnection (double flash of TV device button). If I connect it the other way around, it continues to work... ...so which is the correct way round to connect the cable? I presume it's the first way, and that the device is in 'permanent reset' (according to Tommy Tyler's Rev5 Doc)

There should be a groove on one side of the 6-hole IDC connector, this groove should be on the side of the 6-pin where pin1 is indicated on the remote's PCB.

Sometimes there is a "1" printed on the PCB to indicate pin1, sometimes there is an outline around the 6-pin where one corner is "cut away" where the cutaway indicates pin1.

Thanks Rob, if it's what I think you mean it's more 'keyed' than a groove, but I think this answers my question.

Sadly, all that happens when I plug it in like this is that all the remote device lights illuminate and IR.exe gives me the errors mentioned above. I'm rapidly running out of things to try?

Have you tried the various different battery combinations, as detailed here...

Hi Rob, yep I've read that post and tried all of them but I still get the same error. The only reason I can be certain the interface is even doing anything at all (as opposed to there being nothing plugged into the parallel port) is the two different error messages I get when connected/disconnected from the remote, as detailed above. It looks like I might have reached the end of the road! Has anybody reading this forum had any success at all with the 7562?

Have you checked to see if any wires have come loose in the cable itself...

I have LOTS of problems with my parallel JP1 simple interface cable. (My Jp1.usb and my JP1.2,serial don't have this problem)

If my remote sat without batteries for an extended period of time it may need a few hours to get to the right voltage. I often find that my new remotes won't talk to the JP1 until they have had the batteries in for a few hours and then I need to take the batteries out for the remote to communicate. Each time I try a new remote its a struggle, but definately worth the effort.

Well i have the URC-9910 and was having similiar problems. I plugged it in according to DIy's website. With the ribbon pointing up. Mine had a little key in it so the cord itself looked like a small T If I put it in there with the key facing up the LCD screen showed all warnings and words. Kinda like what you are describing with the lights. if i put it in there the other way with the notch down it still worked but it the interface would not read it...

Now what i did to fix it

First of all I noticed sometimes it would say mem fault and reset and other times t wouldn't. I changed in bios what type of printer port I had it was set up for like an EPP port I changed it to an ECP port. From there i rebooted computer and I also did a full reset of the remote (this seemed to work the most). I than noticed it switched from saying Interface not responding to Remote not responding. So I went through all the other battery configurations and found out I had to take out a battery and hit a button, then plug in cable and it worked!

aevans0001 Rob and co.

Thanks so much for these suggestions - it's really quite frustrating but I will keep trying! In particular, I haven't thought of hitting a button on the remote before I plug in the cable, so I'll try that when I get home tonight. I'll let you all know how I get on.

Anyone out there successfully used a JP1 cable with a 7652?

I have no problems with the "parallel JP1 simple interface cable" and my 7562.

To use it from my laptop, I had to connect the metal outside of the parallel port connector to the ground pins.

[carlosp_uk]

connect the metal outside of the parallel port connector to the ground pins.

Thanks for this info, can you clarify exactly how you did this? I am no good with a soldering iron in general unless it's the only way!

[wimfabri]

it involved soldering. But this is only needed if you get no ground connection on the normal pins.

Hi there

Well, I tried the suggestions above, but sadly to no avail; I don't have access to a soldering iron so I couldn't try and ground the outside of the parallel plug, but I did try from a laptop and a desktop PC and in both cases I get the "no response from interface" error in IR.exe v7, whether the cable is connected to the computer or not!

...so in desperation I started thinking about doing it by WAV again and thus trying to patch the .IR file today, so I did the following, (with very little knowledge of what I was actually doing - apologies):

1. I renamed the file EBX0EBV0 (URC-7560_7562 Extender).RDF to EM60EM60 (URC-7560_7562 Extender).RDF This seemed to mean that the remote control now accepted the WAV transfer. (presumably because the fifth byte of the resultant .IR file when saved in IR.EXE was now 36 which I deduced is the correct signature of my remote)

2. I loaded IR.EXE, went to File>New>7562 Extender, and then configured the devices/macros/etc. I transferred it all to the remote by WAV. However, nothing happened when I tried to activate the extender.

3. I checked the extender documentation for urc7560-extender-v2_1.zip (which I found in the forum file area) unsure if this was the same RDF as distributed in the RDF zip file, or an older one. In this documentation were a set of installation instructions for the extender which involved making changes to various bytes in the .IR file. I carried these out, OMITTING the beginning bit which involved changing the signature back to what it was. I also followed the doc instructions to add the necessary protocols/devices in IR.EXE

[^ should I have done this? Or do .IR files made using the 'built in' extenders in the RDF distribution (i.e. load IR.EXE and go to File>New>7652 extender) already contain this necessary code?]

4. I used IR2WAV again to upload to the remote. It double blinks to accept the transfer at the end. However, when I try to activate the extender (by pressing 10 & AV together), nothing. The remote totally locks up and needs a reset to make it work again.


What am I doing wrong?! I just want to try and get my remote control working. Heeeeeeeelp.

PS: If I was to post my .IR file created using the basic File>New>7562 Extender, is there anybody who could patch it for me to work?

Carlos

yes, please post your IR file (into the Diagnosis section of the File Section - https://www.hifi-remote.com/forums/dload ... &cat_id=35)
and reply with a link to it here

I have a couple of 7562 remotes here I can test it with.

I'm assuming your 7562 is the B00 variant, rather than the B01 - because I don't think you can use the extender at all with the B01 - this later variant is quite different to the B00. (different keymaps and some other changed behaviour - also completely different signature and hex code at the start of the IR file)

You can find out which one you have from the sticker inside the battery compartment.

I've got a B00 and a B01, so I can look at your IR file whichever version you have.

Incidentally, I have no problems with several different 7562 remotes and 3 different Pcs I use my Simple interface cable on - one of which is a laptop.

So...

Did you solve your problems ?
