I have purchased a used a Philips LTC 0809 AutoDome camera.  
  
  
I was able to power it on, and it works fine.  
The pan/tilt/zoom +other options are controlled via  
Allegiant Biphase Protocol  
some kind of serial protocol, the connections are Shield, BP+, BP-  
Does anybody know what this protocol is, how can i create or emulate it?  
  
Thnank you,  
  
Boris.
