I've read Barry Gordon's paper on IR codes and understand a little bit more now. It appears that the Pronto must be 'seeing' the 100 KHz signal and is actually recording some sort of code although it does not work.

This is the code for:
Digit 1
0000 005a 0003 0003 0005 0007 0001 2403 0009 0442 0004 0004 0003 0004 000c 0442

Digit 2
0000 0059 0003 0003 0005 0007 0001 17f9 0007 044f 0004 0004 0003 0004 000a 044f

Digit 3
0000 005a 0003 0003 0005 0007 0001 02cc 0008 0442 0004 0004 0003 0004 0009 0442

So what has the Pronto seen. Is there any way to use ProntoUtil to get these codes to work? In fact, what is the maximum frequency that the Pronto can transmit.

By the way the software version I have is Sys V3.6 App V4.81 which I beleive is the latest.
