fernandopv 0 Posted April 16, 2015 Hi, just registered at this forum. I have some old cameras and an old video matrix I think is Plettac. This matrix has two control ports for PTZ, one for 'ORBITER' and another for FWE (long and short kind). There's a protocol adapter device, 'backyard made by some guy' not giving any reference of maker. This device converts ORBITER to 'whatever', but now it doesn't work anymore. While this system where working, i never had the time to 'analyze the protocols' . Looking for some reference to seach, I've seen pencil writen on EPROM memory: 'ORB to PHI'. It has a Xilinx FPGA or something alike on the main board, (european size). There's also a coupler board having on it two small signal transformers and two SN75... bus drivers. The output of this coupler goes to every cameras PTZ input boards. The question is : does somebody know , 1) what protocol could be using the cameras PTZ receivers? 2) a suitable converter for this? 3) else , any document or source code about orbiter protocol? 4) could it be 'biphase Bosch' or biphase philips ? Sorry for that many questions. I wish to help too on whatever I could. Share this post Link to post Share on other sites
