I have an encoder that I attached to it on a serial port an analogue camera and a ptz motor. The camera is controlled via a keyboard specific to this task. In addition, the cable used between the ptz motor and the encoder is coaxial and uses a converter from coax to serial.
I’m having pb with the PTZ when I move the joystick on the keboard to control the PTZ, the camera starts spinning.
I want to take traces when I move the PTZ between this camera and the encoder to try to analyse them. However, I want to filter this trace on IP address of the encoder and that specific serial port that the camera is attached to it . The reason is that I have many other cameras attached to this encoder as well but on different port. How can I do a trace with a filter on a specific serial port through wireshark and how to know the port number? what is the syntax ? should i use the UDP port ? If yes, is this UDP port is different than the others used by other cameras ?
