Unit connectors

Network and power - RJ-45 Ethernet connector supporting Power over Ethernet (PoE class 2). Using shielded cables is recommended.

Video in - For connecting an analog camera:

•BNC connector. Use a 75 ohm coaxial video cable; recom- mended maximum cable length is 250 meters (800 feet).

Note: If the video source is to be connected in parallel with other equipment using a BNC T adaptor, disable the input termination by setting the 75 Ohm termination switch to OFF. Failure to do so may reduce image quality.

•2.5 mm tele plug connector.

RS-422/RS-485 connector - Two 2-pin terminal blocks RS-485/422 serial interface for connecting auxiliary equipment, for example Pan Tilt Zoom devices.

The RS-485/422 serial port can be configured in the following port modes:
• Bidirectional RS-485 half-duplex port for data transmission
using two wires, one combined RX/TX pair.
• Bidirectional RS-485 full-duplex port for data transmission
		TX			RX/TX
using four wires, one RX pair and one TX pair.

• Unidirectional RS-422 port for transmitting or receiving data

using two wires, RX- or TX pair.

•Bidirectional RS-422 full-duplex port for data transmission (point-to-point) using four wires, one RX pair and one TX pair.
