Help with JP1 pins installed on RCU810

mirx · Post by **mirx** » Wed Feb 21, 2007 7:15 pm

Hi,
I received my JP1 cable and pins.

Long story short, I can't get the software to read from the remote.
I wish there was more extensive instructions around soldering in the pins and testing them.

I am using Parallel Port Address: 378
which I assume is LPT1, the parallel port works fine with my parallel port printer.

With this setting I get:
"No response from the Remote. Make sure your Interface is plugged into JP1 properly."
With other port settings I get:
"No response from interface. Make sure the interface is connected to the PC, and that you're specified the correct port."

When I click download from remote, it prompts "Ready to download From Remote"
after I click OK, the every character and image on the remote's LCD display lights up all at once and stays on for a couple of seconds, before going out.
Then I get: No response from the Remote. Make sure your Interface is plugged into JP1 properly.

I'm using the cable and pins I recently purchased from this site, that I soldered myself.

I'm not sure what else i can test, I've tried various battery arrangements, with and without, weak, none, strong, etc.
With the JP1 reversed (1->6) and proper (1->1).

Can someone please help me troubleshoot this, much appreciation.

Soldering in the RCU810 is pretty straight forward, pull the remote apart, pull out the board, stuff the pins through the holes and solder on the back side. Make sure that you let the solder heat up enough so the joints are not "cold" there really isn't anything else that can go wrong.

As for the interface. My RCU810's from a while back always needed batteries in them for the JP1 stuff to work, so I'd start there. Make sure that you have the cable plugged in right, it can go in two ways. Try both and then remember which one works.

(this list is more comprehensive than you may need since you have a working printer, but is here for others that may find this)

Is your machine running XP? If so, did you copy the system file into the system folder? (gwiopm.sys into C:\windows)

Right click on my computer, go to properties, then hardware. Click device manager and then click the plus sign next to ports. is your parallel port there? (may say ECP printer port but will say LPTx)

If it's there, right click on the printer port and go to properties. Click on resources and look at the IO address? Does it match the one that you are using in IR? (LPT1 is IO 378-37F)

If it's not there, shut down and get into your BIOS setup program and find where the ports are enabled. IS the LPT enabled? If not, enable it and reboot. Windows will find it and install the drivers and then you can check again.

good luck

Thanks for the quick reply!

See inline comments...

I tested the continuity of all the pins with a multimeter from the top of the pins to soldered underside, and they all had continuity.

I have good working batteries in the remote.

Make sure that you have the cable plugged in right, it can go in two ways. Try both and then remember which one works.

I have tried both ways, neither one works. That's the problem :-s
The plug has a triangle Pin1 indicator on it, which when I line it up with pin1, results in the remote being reset (ie the clock resets to 12:00, from the proper time), and I get the "No response from the Remote" message from IR.exe.
When I reverse the plug, triangle to pin6, I just noticed it is now sometimes resetting the remote immediately other times not, but it always gives the error message: "No response from interface"

(this list is more comprehensive than you may need since you have a working printer, but is here for others that may find this)

Is your machine running XP? If so, did you copy the system file into the system folder? (gwiopm.sys into C:\windows)

Yes, I'm running XP
No, I didn't copy gwiopm.sys to the C:\windows directory, I didn't see that mentioned anywhere, but I will now.
I did copy DecodeIR.dll to the C:\Windows\System32\ directory, as mentioned somewhere else thought.
After reading your post, I tried copying both files to both locations, and it didn't seem to make a difference.

Right click on my computer, go to properties, then hardware. Click device manager and then click the plus sign next to ports. is your parallel port there? (may say ECP printer port but will say LPTx)

If it's there, right click on the printer port and go to properties. Click on resources and look at the IO address? Does it match the one that you are using in IR? (LPT1 is IO 378-37F)

If it's not there, shut down and get into your BIOS setup program and find where the ports are enabled. IS the LPT enabled? If not, enable it and reboot. Windows will find it and install the drivers and then you can check again.

My port was listed there as Printer Port (LPT1) , with I/O Range 0378-037F.
I have IR.exe set to use Parallel Port Address: 378

good luck

Thanks again.

Since none of this helped. Any further advice would still be really appreciated.

I can't remember but this can't hurt. Restart after copying the system files and see what happens.

(God I hate windows. This post coming to you from my trusty Mac!)

Thanks,

I tried the reboot... unfortunately, it didn't have any effect.

Hopefully you or someone else will have some additional experience to share.

*crosses fingers and waits for another tip*

Thanks.

two more suggestions:

1: download the schematic of the simple JP1 parallel cable that you have and since you said you had a meter, make sure that the connections are right and that the cable isn't defective.

2: solder the pins in the other remote and check to see if the first remote doesn't have something wrong with it.

Since I ordered it from this site, I was assuming/hoping that it wouldn't have any problems, but really stuff is always prone to problems

2: solder the pins in the other remote and check to see if the first remote doesn't have something wrong with it.

Yeah, I suppose at this point, I'll have to consider that option.

Thanks for your continued help.

With XP, you probably just have the c:\windows directory, but maybe not, maybe there's \winnt as well. Assuming your system drive is C,
Copy gwiopm.sys to C:\windows\system32 or C:\winnt\system32 or just keep it with IR in the same directory. The copy, is needed mostly when you run IR off the network drive or if the IR directory itself is not on the system drive.

It sounds to me also like it's a hardware issue, could even be the remote itself. But in the cable, check that all the grounded pins that should be connected, are connected.

I don't think Rob sells JP1 cables, does he? Probably can't blame him as we blame Mikey

I remember reading here once that someone with a printer and jp1 cable had failures of some sort when switching them around on the port. I wonder if some temporary killing (device removal) of the printer might help. Windows gets confused too easily.

Did you ever get this sorted out, my RCU810 is behaving the exact same way?
