AXIS M7001 - Unit connectors

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; recommended maximum cable

length is 250 meters (800 feet).

Notes:

• 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.

• If the same video source is used as input to several video encoders, enable

termination on all encoders.

• 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 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.
