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).

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.
