I misunderstood the device and command bytes sections. I also had the lead-in style wrong. Your protocol and upgrade work perfectly. I assigned most of the buttons, and now I'm playing around with macros and such. Thanks so much for your help!

One note, though: Sunfire is Bob Carver's new company ...

I've had that signal structure selected from the start, so I guess that's not the problem. I have no bit doubling, no repeat value, no check byte, lead-in on first frame only, lead-out style 0 "off as total", no alt lead-out, and no toggle bit. I have switched all of these settings with no success ...

I haven't had any luck so far with building this protocol. I am confused about how to represent the ~D:4,~F:8 portion. I have tried to use the XOR and XOR-Comp for check bytes, but this function isn't documented very well and my boolean logic is rusty... I don't see how XOR would invert a signal ...

Yeah, I figured out the part about merging the last with the lead out to get 12 bits of !data+lead-out. I haven't gotten far enough in my understanding yet to make much sense out of jon_armstrong's decoding, but I'll work on it after I get home (from my *real* job) today and hopefully figure it out ...

Re: old Yahoo thread on Sunfire protocol

I am attempting to build a Sunfire protocol, but I am very new to all of this. I have read most of the JP1 documents, and I think I understand most of it. However, I don't see how you came up with "3 device bits" from looking at the Sunfire Pronto document ).

I see that there are 12 "data bits ...
