Unit connectors

Network - RJ-45 Ethernet connector. Supports PoE (Power over Ethernet, class 3). Using shielded
cables is recommended.
Audio in - 3.5 mm input for a mono microphone, or a line-in mono signal (left channel is used
from a stereo signal). An external microphone must be used to for audio detection.
Audio out - 3.5 mm output for audio (line level), can be connected to a public address (PA) system
or an active speaker with a built-in amplifier. A pair of headphones can also be connected. A stereo
connector must be used for audio out.
RS-485/422 - 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.
