I'm not quite sure what is being referred to here, but if you mean the 
BadNixie PIR, there are 2 versions of it - the wired one which is the 
standard PV Electronics one, and the wireless one. The wireless one uses 
the MOD-SIX wireless protocol to communicate with compatible clocks. At the 
moment there is no documentation or code samples available for people who 
might want to use it with other clocks.

To answer your other question, neither version of the PIR shuts down the HV 
supply. While there has always been a HV enable / disable jumper on the HV 
supply in the MOD-SIX, it was put there as a diagnostic aid (AKA "don't 
electrocute yourself when testing other boards"). It was never bused 
through the TDU boards to the processor, so there is no way to remotely 
shut down the PSU on the current clocks. It has been discussed as a 
possibility for future designs, but that depends on how much of the 
existing hardware will be used - I haven't asked about what's coming next, 
honest!

That reminds me - I should get the revised MOD-SIX manual to Michael so he 
can post it.
