RS-422/RS-485 connector - Two 2-pin terminal blocks for RS-485/422 serial interface used to control auxiliary equipment, e.g. PTZ 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.

SDHC memory card slot - The high capacity SD memory card can be used for local recording with removable storage.

BNC connector - Connect a 75 ohm coaxial video cable (max. length 800 feet (250 meters).

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 cause reduced image quality.
