Hardware setup

This chapter contains detailed information about the hardware installation and connection of
external equipment to the unit. The connector types and their pin signals are described. Most
of the connectors are located at the rear panel of the unit (see Connections, page 17). For
convenience, one USB port is located on the front of the unit to connect a mouse or memory
device.
All the input/output ports are Safety Extra Low Voltage (SELV) circuits. SELV circuits should
only be connected to other SELV circuits.

Camera connections

Connect cameras to the VIDEO IN connectors on the back of the unit using 75 ohm video
coaxial cables with BNC connectors. Optionally on the DIVAR 5000 family, this signal can be
looped through to other equipment via the corresponding VIDEO OUT connectors (or the
video out D-connector on the DIVAR 5000 16-channel model). The camera input connectors
are auto-terminating. There is no need to add a terminator to the output connector if no
additional equipment is connected.
If the camera signal is looped through to additional equipment, make sure that the end of the
video connection is terminated with 75 ohm termination.
The DIVAR family can be configured as a PAL or NTSC unit by manually setting the TV standard
to PAL or NTSC in the General setup menu.
