RS-232 vs RS-485 Control Cabling (DB9 and RS-422 Explained)

RS-232 vs RS-485 Control Cabling (DB9 and RS-422 Explained)

In this tech support Tuesday Andy Chatfield reviews the RS-232 and RS-485 PTZ camera control options. A common technical support question for Andy is "Should we use RS-232 or RS-485 for camera control?" Andy answers this question and reviews the differences between RS-232, RS-485 and RS-422 (which PTZOptics cameras do not support).
Andy goes over the complete Serial Joystick connection diagram for controlling multiple cameras and makes suggestions on cabling that can be used. A common implementation of camera control cabling is actually using something that integration companies already have run in the walls such as Cat-5 or Cat-6 cabling. Andy explains how to use Category Cabling camera control including the various pin-outs required for camera control. Finally, we review the different baud rate options for joystick and camera controllers. Andy is the lead support technician for PTZOptics and he asks users to submit a ticket or call the PTZOptics 1-800 phone number with any technical questions.
