Sorry to wake up this thread, but I am having the exact same problem.
I am using Win7 Pro 64-bit, latest Phidget version 2.1.8 Build Oct 15 2012 14:27:23
I am testing using the built-in UI for PhidgetIR that comes with the library.
I let PhidgetIR detects the code, and make sure I am not placing the remote control too near.
The Phidget is able to learn the code alright.
If I press the Re-transmit button, it works fine.
But, Send RAW Data button doesn't work.
For what it worth, I am writing a program to send both learned code & raw code, and it has the same problem: only learned code works, raw data doesn't work.
Here is a screenshot of what's going onhttp://dl.dropbox.com/u/11295402/Screenshots/phidgetIR.png
Any advise on this?
