JP1 Remotes

I'm trying to get my OFA URC 7800 to learn the codes for my Sony STR-DB930; especially the code that turns the Surround Fields off and on. My OFA 8910 learned this code just fine but the URC 7800 just blinks once, meaning it can't learn the code.

Are there some codes the URC 7800 can't learn or are too long for the URC 7800?

Or have I somehow screwed up these learning buttons for my Audio device? The learning buttons work fine for my Toshiba 65H80 tv.

I need to know this before I go ahead and buy a JP1 cable and get into this whole JP1 programming thing.

One last question: Is it hard to solder the JP1 male header into the URC 7800? All it has is holes now. Is there anyplace that describes the soldering needed?

Thank so much.

The 7800 should be able to learn everything that the 8910 can learn, but as long as one of the remotes can learn the signals in question, that's all you need to create a JP1 upgrade.

You might have used up the learning memory on the toshiba tv.

Robman:

Thank you so much for your help. I have now opened up the remote and am looking at the PCB board, and I see where the 6-pin will be inserted. There are 6 lanes (lines) leading from the area where the pins will be inserted, one for each pin. It's obvious that I don't want to get any solder between the lanes.

So I put some flux on the 6 holes in the PCB, then insert the pins. I assume that I put the flux on the side of the PCB where the lanes (lines) are. Is this right?

Now you say "Solder it". Where do I apply the solder so that I prevent it from crossing pins and lanes?

Sorry if this seems to be a stupid question but I've never done it and you've done it like a million times. I just don't want to screw it up! Surprised

I think I understand now how to do it. I haven't received the 6 pin header yet, so I don't know what it looks like. But I now assume that it has pins going in 2 directions (front and back), with a board in between. The longer pins and the board go on the underside of the PCB with the shorter pins going through the holes in the PCB. Then I just put a tiny drop of solder on the pins going through the PCB.

Have I got it?
