Trying to create ir commands for a Gryphon Callisto integrated amp. Unfortunately the remote has not worked in a long time so is not available to learn from.
The remote uses the Philips RC-5 standard and is system 16.

The commands I am trying to create are
ON/OFF 12
MUTE 13
VOL UP 16
VOL DOWN 17
INPUT UP 32
INPUT DOWN 33

I found some useful information in an old thread

[Link: remotecentral.com]

about another Gryphon device. The volume up key listed there works using his hex data
0000 0073 0000 000B 0022 001D 0042 003B 0042 001D 0022 001D 0022 001D 0022 001D 0022 003B 0042 001D 0022 001D 0022 001D 0022 0CAC

I have tried using the RC5 to Hex tool by Dan Grey, and none of the hex codes I produced worked.

example ON/OFF 16 12
0000 0073 000B 0000 0020 0020 0040 0040 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0040 0020 0020 0040 0020 0020 09B7

I also tried using PEP 3 and it produced this code (also not effective)
ON/OFF 16 12
5000 0000 0000 0001 0010 000C

Any advice would be appreciated.
