radiotech1 0 Posted October 1, 2016 Hello everyone. This is my first post and I have searched around and did not find my answer. I have a Dahau network box camera and it has an aux interface port for RS485 devices. I would like to know if it is possible to connect a RS485 decoder to this port on the camera and then control the motorized zoom lens by sending the commands down the network cable from the camera's webpage.
