If it's NEC, then I'm pretty sure I know what the codes are.

I emailed a set of signals to you for testing. The function number in the label above each of the signals in that email corresponds to the last two characters of the code in the form you quoted in post 1 of this thread.

I hope it's just the original remote you don't have yet, not the device itself. Because I'm not 100% sure about the codes I emailed. You'll need to test to see if they really work.
