Peter asked the right questions. I'll just confirm that PENG transformed the code correctly. If that 900A form is wrong, I'm pretty sure the original long code is also wrong.
The signal (either form) is the "Resize panel" function for the InFocus projectors in these two CCF files
[Link: remotecentral.com][Link: remotecentral.com]So it isn't a bad signal. If it is wrong, I guess that means it isn't the signal used by your model of projector.
Edit: I typed the above before seeing your reply

The long form of code was created with MakeHex. It worked
well for all the other buttons (NEC1 protocol, device
135.78 and command 34)
The command is hex 34 (decimal 52). Is that what you intended?
