6131 has holes labeled "JP1" - Is it JP1 enabled?

Hello all.
I'm totally new to all this, but searched around the forums and couldn't find an answer.

I've had a One For All 6131 for a couple years now and it has done fine for all my devices using just normal setup codes and some advanced codes. I just got a new TV, however, and there are a few buttons that can't be added with advanced codes. I considered sending it in to OFA but figured it would be more fun and interesting to get into the whole JP1 thing.

I don't remember where I bought the remote, but if I open up the battery compartment, there ARE 6 holes below (not beneath) the batteries, labeled "JP1". Does that mean that the remote is already JP1 enabled, or do I still need an EEPROM and all that?

If it IS already JP1 enabled, can I just order the JP1 cable from Hovis (http://www.hovisdirect.com/JP1_options.html) and get going? Or do I need the JP1 cable and a pogo adapter since I have holes there but no pins.

Thanks for any help and guidance you can give!

Rob,

Thanks for the quick reply. I read that post, but it didn't seem to mention remotes where the label "JP1" is already on the inside of the remote. Is this label just an indicator of where to solder the header and EEPROM? Or does the label indicate that yes, indeed I ordered a remote that was already modified for JP1 capability (since I don't remember where I ordered it from).

Thanks again!

For remotes that don't come with the header installed (like your 6131) the "JP1" is just an indicator (of wher the header goes). You'll also need to install the EEPROM which is marked on the PCB as "U2".

Or does the label indicate that yes, indeed I ordered a remote that was already modified for JP1 capability

If the header isn't installed, it's likely not JP1-capable yet...

When the manufacturers wrote "JP1" on the board did they mean for the connector to be called by that name? Or do they really mean for the bit on the board that these holes lead to to be referred to as JP1?

JP1 or Jumper1 on computer motherboards refers to the actual connection part which is usually connected/disconnected with a little plastic jumper. The term "JP1.2" confuses that analogy a bit though, it seems to be referring to the type of circuit.

Any answer that we give, referring specifically to these UEI remotes, will be pure speculation, but here's my guess...

The "JP" term usually refers to jumpers, so if you were to find JP1 printed on another PCB somewhere, you could reasonably expect that the header strip installed at that spot is a jumper (ie, you would place a bridge between pins 1 and 2 for a "master drive" or between pins 3 and 4 for a "slave drive" etc, something like that).

So, why is the JP1 6-pin labelled as a jumper? My guess is that this is a pretty lame attempt to disguise the fact that it's really a connector rather than a jumper. Given UEI's general paranoia, I don't think my guess is too far fetched.

Now, as for the JP1.1 and JP1.2 labels, by the time those new labels were used, the JP1 group had been in existance for quite a while, so any hope that UEI might once have had for their little "jumper" thing to work would long since have evaporated.
