Unit connectors
Network - RJ-45 Ethernet connector. Supports PoE (Power over Ethernet, class 3).
Note:
Due to local regulations or the environmental and electrical conditions in which the prod-
uct is to be used, a shielded network cable (STP) may be appropriate or required. Any net-
work cables that are routed in outdoor environments or similar shall be shielded (STP) and
intended for their specific use. Make sure the network switch is properly grounded. See
Electromagnetic Compatibility (EMC) for regulatory requirements.
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 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.
