I was working with an old Pioneer DVD player this afternoon, and dug up this thread: [Link: remotecentral.com]

I was looking for discrete on/off codes and found: [Link: remotecentral.com]

Then I wondered if I could generate an entire set of hex codes from the associated IRP.

I have a copy of MakeHex.exe which reads:

ReadMe for MakeHex version 5 Copyright 2004 John S. Fine

and whose ReadMe file is dated:

08/12/2007  03:42 PM            10,918 MakeHex_ReadMe.txt

I edit pioneer2.irp to become:

Device=163.175
Define P=153
Function=0..255

Protocol=Pioneer2
Frequency=40000
Time Base=564
One=1,-3
Zero=1,-1
Prefix=16,-8
Suffix=1,-78
Form=;*,D:8,~D:8,P:8,~P:8,_,*,S:8,~S:8,F:8,~F:8,_

From this I get the following codes for Function 186 and Function 187:

Device Code: 163.175 Function: 186
0000 0068 0000 0044 0168 00B4 0016 0044 0016 0044 0016 0017 0016 0017 0016 0017 0016 0044 0016 0017 0016 0044 0016 0017 0016 0017 0016 0044 0016 0044 0016 0044 0016 0017 0016 0044 0016 0017 0016 0044 0016 0017 0016 0017 0016 0044 0016 0044 0016 0017 0016 0017 0016 0044 0016 0017 0016 0044 0016 0044 0016 0017 0016 0017 0016 0044 0016 0044 0016 0017 0016 06DA 0168 00B4 0016 0044 0016 0044 0016 0044 0016 0044 0016 0017 0016 0044 0016 0017 0016 0044 0016 0017 0016 0017 0016 0017 0016 0017 0016 0044 0016 0017 0016 0044 0016 0017 0016 0017 0016 0044 0016 0017 0016 0044 0016 0044 0016 0044 0016 0017 0016 0044 0016 0044 0016 0017 0016 0044 0016 0017 0016 0017 0016 0017 0016 0044 0016 0017 0016 06DA

The other post shows the discrete on/off codes as roughly:

0000 0067 0022 0022 0156 ... 0016 03fe 0156 00ab ... 0016 03fe

I obtained a copy of IrTool.exe:

24/02/2010  02:11 PM           325,632 IRTool.exe
27/08/2011  02:21 AM           251,392 DecodeIR.dll

Putting each of the codes from this post into IrTool.exe I get:

Power Off
    Carrier 0067
    0 = 0016 0016
    1 = 0016 0040

    Protocol Pioneer
    Device 163
    OBC 153
    EFC 1
    Lead in 0156 00ab
    Lead out 0016 03fe

    Protocol Pioneer
    Device 175
    OBC 187
    EFC 35
    Lead in 0156 00ab
    Lead out 0016 03fe

Power On
    Carrier 0067
    0 = 0016 0016
    1 = 0016 0040

    Protocol Pioneer
    Device 163
    OBC 153
    EFC 1
    Lead in 0156 00ab
    Lead out 0016 03fe

    Protocol Pioneer
    Device 175
    OBC 186
    EFC 31
    Lead in 0156 00ab
    Lead out 0016 03fe

When I put the IRP generated codes into IrTool.exe, the popup dialog is consistent with the above results but the main dialog shows a confused result:

• Why does the IRP generate a different set of hex codes to those posted ?
• Why can't the generated hex codes be parsed by IrTool.exe ?

The version of pioneer2.irp that is in the zip distribution matches the one reported here:

I believe the content of the FORM section is wrong:

Form=;*,D:8,~D:8,P:8,~P:8,_,*,S:8,~S:8,F:8,~F:8,_

Compare it with the one used here:

[Link: remotecentral.com]

Form=*,D:8,~D:8,P:8,~P:8,_;*,S:8,~S:8,F:8,~F:8,_

I think there is a good chance that this is the cause of the trouble, but I don't have time to try it right now.

Consider following the method in post #3, which uses a more modern program.  BTW, that post shows entry of device numbers etc in hexadecimal notation, since some Pioneer documentaiton is written that way, but it is fine to use decimal instead.
