Hi I am working with a Polycom viewstation and this nice tsu3000. And I am having the hardest time learning the codes for the numberpad. I have a document from the manufacturer showing me what the codes are supposed to be but the Learned Strings are much longer and in most cases dont seem to contain the manufacturers string at all.

Example of Learned IR Code for the Number 1 on the Keypad:
0000 006B 0000 0012 0065 0065 0016 0022 0016 0022 0022 002E 0022 002E 0016 0022 0022 002E 0016 0022 0022 002E 0022 002E 0022 002E 0016 0022 0016 0022 0016 0022 0022 002E 0022 002E 0016 0022 0016 091B

Documented Code for the same key:
RM_ONE 0x0E

Another Example is Number 2
Learned:
0000 006B 0000 0012 0065 0065 0016 0022 0016 0022 0022 002E 0022 002E 0016 0022 0022 002E 0016 0022 0022 002E 0022 002E 0022 002E 0016 0022 0016 0022 0022 002E 0016 0022 0022 002E 0016 0022 0016 091B

Documented:
RM_TWO 0x0D

Can anyone shed some light on this for me? Thanks in advance for any help.

There are signals for the Polycom Viewstation at
[Link: ir.premisesystems.com]
You should be able to copy those and paste them into ProntoEditNG.

I've never seen that protocol before, so I can't tell exactly how the command numbers (0x0E and 0x0D in your examples) are encoded in the timing data (the long strings of Pronto Hex that you learned and that you can copy from the above URL). It is normal that the Pronto Hex is much longer than the command number it encodes and doesn't directly contal that command number.

I don't see anything about these signals that would make them harder to learn than typical IR signals. Are you trying to learn with the TSU3000 stand-alone, or while it's connected to your PC? That may make a big difference, though in theory learning should be possible either way.

Does the document from the manufacturer give any more detail about the structure of the signals? I'd like to add this protocol to my decoding software. I might be able to guess the structure from the samples at premise, but the manufacturer's document would make that easier. Can you email a copy to me?

Well I think the problem is not that it wont learn but rather the codes seem to be sending something other than the simple discrete code. I have tried those Polycom codes from premisesystems and they kinda work. The bigger problem is when i try to dial a number I can get maybe one or 2 numbers across then it freezes.
