100BaseFX Ethernet Port Connection

The concept behind the SC port and cable is easy to understand. Since optical signals do not require a circuit to transmit data, one cable is used to transmit data and one cable is used to receive data, providing 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 351’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.
