RS-485 Wiring Diagram

Question: How many PTZ cameras can I connect via RS-485 and how do I wire them up?
Answer: You can link up to 32 RS-485 Devices, including any control devices (keyboard/recorder)
This would in effect permit up to 31 cameras (as long as only 1 controller is in use)
The camera at the end of the RS-485 run, should be terminated.
