Ok thanks again. The actual installation is still one month away. Right now I am just studying the manuals and getting prepared. I will let you know how it comes out.

Thanks for reply Numb-nuts. This is my first PTZ so please bear with me. I am re-looking at pg 33 of the manual and I see picture 9.6.2 on the bottom of page. It shows A+ connected to #2 and B- connected to #3. What I am not understanding is what does daisy chaining mean in this context? Does it mean using more than on PTZ in system? My system will have only one PTZ so does that mean that I plug the 120ohm resistor into jumper position #2 and #3 for factory default setting? Or do I use the jumper cap at all? It looks like picture 9.6.3 is saying to insert jumper cap for the daisy chaining option.

Can someone explain in simple English how to connect the Rs485 bus of a QSTD2408 DVR to the PCB board on a COP CD55NVT PTZ? I will be using cat6 cable and the distance between the DVR and PTZ is about 150 feet. Page 33 of the CD55NVT manual does not show exactly where to connect the A+ and B- wires and if I need to use the 120ohm resistor? thanks very much
