RJ45 (8-pin) to RJ45 (8-pin) Cross-over Cable Wiring
COM Port
A COM PORT is located on the front panel for connecting a PTZ motorized
camera or serial device. The COM port transmits RS-232 or RS-422/485
signals over the TCP/IP network. Users can use this COM port (DB9 male
connector) to monitor data or control a serial device, or for the control of
a PTZ motorized camera.

NOTE
This COM port is mainly for the serial-to-Ethernet connectivity. It
supports TCP Server and TCP Client modes (after the V1.1
firmware version is released).
PTZ port
A PTZ port is located on the VPort 464’s front panel. The port is used to
connect 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 a terminal block. The
PTZ port pin assignments are shown in the following table.
