PTZ Port
A PTZ port is located on the VPort 251’s front panel. The port is used to connect to a PTZ
motorized camera or device, so that the camera or device can be controlled from the VPort over
the IP network. The PTZ port supports RS-232 or RS-422/485 signals through the terminal block.
The PTZ port pin assignments are shown in the following table.
