Hi Jason,
Edit the last word of the RC6 Hex Code from 0000 (0 in Hex) to 00FF (255 in Hex). You can use the Calculator in Windows OS set to Scientific Modes to convert Decimal to Hex.
e.g.
6000 0000 0000 0001 0046 000C
to
6000 0000 0000 0001 0046 0000
Until you reach,
6000 0000 0000 0001 0046 00FF
I already did this but just found the code for power off. No code works for discrete power on. Does this mean the unit doesn't support discrete code for power on at all - or should I try the other methods you've listed?
Thanks
Punga
