RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring
100BaseFX Ethernet Port Connection
The concept behind the SC port and cable is quite straightforward.
Suppose that you are connecting devices I and II. Contrary to electrical
signals, optical signals do not require a circuit in order to transmit data.
Consequently, one fiber optic cable is used to transmit data from device I
to device II, and the other fiber optic cable is used transmit data from
device II to device I, for full-duplex transmission.
Remember to connect the Tx (transmit) port of device I to the Rx (receive)
port of device II, and the Rx (receive) port of device I to the Tx (transmit)
port of device II. If you make your own cable, we suggest labeling the two
sides of the same line with the same letter (A-to-A and B-to-B, as shown
below, or A1-to-A2 and B1-to-B2).

PTZ port
A PTZ port is located on the VPort 364’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.
