I've just bought a PVR and I learned the signals. It uses the Nokia32 protocol which I have used before either using the Galaxis sat protocol or using setup code 1111. The signals I have learned have exactly the same Device, Sub-Device, OBC, HEX and EFC, but the Misc data is different. On the Galaxis it uses a fixed X=8, with my PVR the Misc data is either X=45 or X=173. The Galaxis protocol does not control the PVR.
What does the Misc Data represent and how would I modify a protocol to incoporate it?
The Galaxis protocol and upgrade can be found here.

Any help much appreciated.
Nokia 32 and learned Misc code

Been looking around the forum, and found this post https://www.hifi-remote.com/forums/viewt ... 1195#p21195 which explains how to convert the fixed data and obcs to the required hex for the upgrade. I've used this info successfully before when converting obcs from the learned data to the 4-byte hex required for the functions for my Daewoo DTT recevier.
In this case though I'm trying to alter the fixed data because the value of X is different - with the original Galaxis upgrade it is 08, with my PVR (a Digifusion FVRT90) X is either AD or 2D (the other two bytes, device and sub-device are the same - 0D 50). I've tried using the method of converting explained by the late Jon Armstrong in his post, but I end with more bits (26 without adding the trailing LSB 0 and leading 1s when using AD), which is too many. I tried adding the LSB 0 and dropping the leading MSB bits to get the required 24 bits (making fixed data of EA 8D BA) but this didn't work and neither did 3A A1 BA which was generated using 2D.

I tried to alter the Nokia 32 protocol to have two fixed bytes and three variable bytes. I learned it back in to another remote and it didn't see it as a recognised protocol. I have learned numbers 0-9 on my OFA5 and uploaded the file https://www.hifi-remote.com/forums/dload ... le_id=2651.
Anybody have any ideas?
