JP1 Remotes

So I've been busting away for a couple of hours trying to figure out how to build a remote from scratch for a JP1 device, based off the original remote. I don't have any JP1 remotes to learn the original remote nor do I have the cable to extract it. I'm just trying to assemble what I need so that I can plug the info into my slingbox solo.

I tore down the original remote and found the following key components.

I've also received a PDF from the manufacture for the remote codes but I can't quite interpret it.

Also I took pictures of the torn down remote.

What is the device that you're trying to control?

I probably didn't get all of the button names correct as your pics are a little fuzzy, but give this upgrade a try...

The device is a 16 channel security camera DVR.

From what I see, that chip makes kinda like an NEC2 code.

I assumed NEC1 for the upgrade that I created. When echos reports back as to whether it works or not, if he says that the buttons don't repeat properly, I'll try changing it to NEC2.

That is because NEC 1 and 2 repeat differently.
NEC1 repeats by repeating the whole 32 bits, NEC2 by sending just one bit. That datasheet shows the repeat bit being sent.

You've got that backwards. NEC2 repeats the whole string, NEC1 just repeats the leadin and leadout with no data bits.
