Panasonic PT-LB51U projector pronto hex codes

[biker.josh07]

Hey there.
I am just a newbie so you will have to explain things in basic terms.I'm looking for the discrete pronto hex power on/off codes for this projector.

My "universal remote" consists of an Atmel AVR ATtiny85v that can be programmed and hooked up to some IR led's to act as a remote operated by one button.

I have tried two panasonic projector codes from www.remotecentral.com ;the 48 data bit and the 56 data bit and both havent worked.

I would also like someone to explain to me what a device code is.The only panasonic projector device code that I have found is 128.72,but surely this isn't the only one.

I have read that modern panasonic projectors use the Panasonic2 IR protocol.The .hex file that is generated from the makehex program requires knowledge of the device code,so this means that each function IR code is unique to that model,right??The Panasonic2 protocol is not generic.I have read the wiki on IRP notation but I need to read it more than once before I will understand it properly.

Also doesn't the pulse time unit differ between regions.ie. in North America the time unit would be 432us but Europe,Australia and New Zealand its ~454us.

If you are wondering why I need to know it is for a University project

Many thanks for your help.

Well that wasn't much of a link, we know where remote central is. We don't know what codes you tried that didn't work.

Not typically. Usually the device code is stable for a manufacturer, although some companies change for every model. That is not typical. If that were the normal way, then universal remotes wouldn't be practical.

The Panasonic2 protocol is not generic.I have read the wiki on IRP notation but I need to read it more than once before I will understand it properly.

Can I steer you to a beginners document that I wrote.

That should help you understand the IRP.

Panasonic2
IRP notation: {37k,432}<1,-1|1,-3>(8,-4,2:8,32:8,D:8,S:8,X:8,F:8,(D^S^X^F):8,1,-173)+


I looked at three models the Panasonic PT-;B51SE, PT-LB51E, PT-51NT on the harmony website and these all used the Panasonic2 protocol.

The power button looked like this
Panasonic2
IRP notation: {37k,432}<1,-1|1,-3>(8,-4,2:8,32:8,D:8,S:8,X:8,F:8,(D^S^X^F):8,1,-173)+

{36.6k,435,msb}<1,-1|1,-3>(8,-4,A:56,1,-71.3m)+{A=0b01000000000001000000000100010010000000001011110010101111}; Alt leadout form: ^139m

The is device 128.72 with an obc of 61.

Also doesn't the pulse time unit differ between regions.ie. in North America the time unit would be 432us but Europe,Australia and New Zealand its ~454us.

I don't know how the region effects this, but Panasonic is reading out at 435, which is close enough to 432, to be 432.
