Remote code change?

[Fidelity 26]

Can a code be changed.Ive got a new old stock remote for the Ferguson 22G2 but its for a few nos higher than the old one.
Can it be changed.

Not without a lot of work.. so the general answer is no. The codes are contained in a fixed function chip.. I guess it would be possible to replace that with a self programmed eeprom, but it was usual for the single chip to contain all the other ancillary functions like clock and led drivers.. Then add to that the problem of finding the actual codes of the pulse chains..

Usually they work for 90% of the functions across a series.. a tx9 supersound remote will work pretty much every tx9 with perhaps the odd "random" key which does something unexpected.

I found that Ferguson used a very wide range of remote control protocols. The TX9/10s, including Supersound ones, mostly used the SAA5012 chipset. The TX100 with FastText used a completely different protocol to other TX100 sets IIRC (it's been a while). Later sets were different again.

An uncle worked for Ferguson back in the '80s, so I've got a fair bit of randomly sporadic experience and documentation for these things. But the short answer to the OP is "what Paula said". Sorry...
