Borisw37 0 Posted January 6, 2008 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. Share this post Link to post Share on other sites
_-0-_ 0 Posted July 22, 2008 Inside this cameras is connector RS 232, question is, if you need in this case Biphase convertor... For communication true 2nd one input ("BiPhase input") you need convertor RS232 -> RS485 and expensive RS485 -> convertor. Share this post Link to post Share on other sites
