converting infocus discrete hex to efc

[ezwrighter]

I could not find a tool or instructions on how to convert a discrete hex function to something resembling an efc that I could enter into KM.

here is the link to the discrete code:

http://www.remotecentral.com/cgi-bin/fi ... jector&fc=

Or

Here is the ON code:

0000 006d 0022 0000 0156 00ab 0016 0060 0016 0060 0016 0060 0016 0016 0016 0016 0016 0016 0016 0016 0016 0060 0016 0016 0016 0060 0016 0060 0016 0060 0016 0016 0016 0016 0016 0060 0016 0016 0016 0060 0016 0016 0016 0016 0016 0060 0016 0060 0016 0060 0016 0016 0016 0016 0016 0016 0016 0060 0016 0060 0016 0016 0016 0016 0016 0016 0016 0060 0016 0060 0016 0593

I would like to be able to do this myself in the future if someone could point me in the right direction.

I am hopeing this code will work for my X1

Thanks,

You use a program called irtool.exe together with decodeir.dll to decode signals in that form (Pronto hex).

That one is NEC protocol (not complete enough to know if it's NEC1 or NEC2) device 135, subdevice 78, command 57.

If you have a compatible setup code that's EFC 025. If you're building a new setup code in KM it's slightly less confusing to switch KM to use command numbers (OBC) rather than EFC, because most descriptions of related commands in threads at RemoteCentral use command numbers (EFC is only for UEI remotes. Command numbers are meaningful across many different universal remote systems).

The IrTool.exe at remoteCentral doesn't have current decoders. You need the one from the Yahoo JP1 group.

Ok....I am still missing something.

When I use the current IR Tool v1.2 and decode the ON discrete code, it produces the following information:

-------------------------------------------------
Device: Kenwood/Yamaha 0 0016 0016
Carrier: 006d 1 0016 0060

One Time:
Device: 20103 Command: 58
Lead In: 0156 00ab Lead Out: 0016 0593
-------------------------------------------------

It seems that the commands match up for the code you provided....but how did you get the protocol and devices out of that information? I don't see anything similar in the decoded information I have here.

EDIT: This is actually the output for the discrete ON code and the hex I provided in my first post was for the off code (57).

It looks like you didn't install DecodeIR.dll in the windows\system directory. But it actually decodes it correctly. 78*256+135=20103. Without the dll, the old program sees the device/sub-device combination as a 16-bit number and converts to decimal.

BTW, there are already two device upgrades for the InFocus projectors in the JP1 Yahoo group files. The Generic already had the discrete power commands and there is one for the X-1 that doesn't have them listed, so perhaps they don't work on that model. It can't hurt to try.

Wow...thats embarassing as all get out! I thought I had dropped that dll into the current directory with irtool. When I went back to triple check....it was not there.

Thanks again for your guidance,
