If the system will include controllable PTZ equipped
cameras, add one LTC 8568/00 Signal Distribution Unit for
up to 32 separate control code outputs or one LTC 8768/00
Signal Distribution Unit if up to 64 separate control code
outputs will be required.
Installation basics:
Install main bay in rack, insert the VIMs and VOMs into the
bay, then connect camera and monitor coax cables to BNC
connectors on rear of unit. Connect one or more local/
remote keyboards for programming and control. If
applicable, connect external PC, external Alarm Interface
unit for alarms, and external Signal Distribution unit for
camera control functions to appropriate data connections
on rear of unit.
System programming can then be accomplished using either
a system keyboard or via one of the optional external Bosch
PC based software packages (see accessory section).
