4.5.2 Video Connections to Products via
LTC 8508/01 Ribbon-to-BNC Cable
Video connections to Allegiant models LTC 8100,
LTC 8500, and other products using BNC video
connectors, can utilize the 1 m (3 ft) 16-channel
LTC 8508/01 Ribbon-to-BNC cable (sold separately).
One LTC 8508 cable is required for each Interface
Unit being installed. Noting the connector orientation
and alignment tab, connect the ribbon connector end
of the cable to the Interface Unit. Attach the BNC
ends to the video inputs on the rear panel of the
controller that corresponds to the physical camera
number range previously determined by the Group ID
switch settings above. For example, if the Group ID
switches have been set to 001, the BNC ends of the
video ribbon cable should be installed in the
controller’s video inputs 1 to 16. For your convenience,
the BNC ends are marked with the video channel
number.
4.5.3 Video Connections to Products via
LTC 8807/00 Video Interconnect Panel
If using a rack-mountable BNC patch panel, or if the
Interface Unit will be remoted some distance from the
controller unit, an LTC 8807/00 Video Interconnect
Panel (sold separately) can be used for video
connections to a controller. Each LTC 8807 panel can
be used with up to two Interface Units, supporting a
maximum of 32 cameras. Connect the supplied video
ribbon cable from the Interface Unit into the upper
connector on the back of the LTC 8807 for the first
block of 16 cameras. The lower connector is only used
if a second Interface Unit will be connected, providing
a second block of 16 cameras.
User-supplied coax jumper cables are required to
complete the video connections between the LTC 8807
panel and the BNC connectors on the controller unit.
Attach the coax to the video inputs on the rear panel
of the controller bay, that correspond to the physical
camera number range previously determined by the
Group ID switch settings above. For example, if the
Group ID switches have been set to 001, the coax
cables should be installed into the controller’s video
inputs 1 to 16.
If the control unit will be located at a remote distance
from the Interface Unit, standard practices for video signal
transmission, and the associated data interface, should be
used (more details provided in the next section).
