2.0 GENERAL DESCRIPTION
2.1 OVERVIEW
The matrix bay is a peripheral product that is part of the System 9760
®
family. The
matrix bay provides all video input and output connections for the system. Each unit is
capable of accepting up to 256 camera inputs in 16 input increments and provides
up to 16 monitor outputs in 4 output increments. If more than 256 camera inputs are
needed, sideframing is required (see Section 5.2); if more than 16 monitor outputs
are needed, downframing is required (see Section 5.1). Version 8.03.006 and later
of CM9760-CC1 operational software enables sideframing and downframing to ex-
tend the number of inputs and outputs allowed to 2048 cameras and 128 monitors.
With the addition of CM9760-MDA (Master Distribution Amplifier) units, a maximum
of 2048 cameras and 512 monitors is supported. Note that the term
camera
includes
any device that can transmit a video signal and the term
monitor
includes any
device that can receive a video signal. VCRs and multiplexers are examples of
devices that can transmit or receive video signals.
All connections are made on the rear of the matrix bay and utilize standard BNC-type
connectors for video connections. All video inputs leave the factory terminated with
75 ohms (standard default). Non-termination (where applicable) is jumper selectable.
2.1.1 Models
CM9760-MXB Video matrix bay equipped with CM9760-MPS power supply.
120 VA, 60 Hz. (UL; cUL; FCC, Class A)
CM9760-MXB-X Same as CM9760-MXB except 230 VAC, 50 Hz. (CE)
CM9760-MXBL Video matrix bay for video loop-out connections. Uses
downframe looping cards (CM9760-DFL). No power required.
2.1.2 Optional Equipment
CM9760-MPS Matrix bay power supply (spare). Operates on 120 VAC, 60 Hz.
CM9760-MPS-X Matrix bay power supply (spare). Operates on 230 VAC, 50 Hz.
CM9760-VCC Video input (camera) card capable of accepting up to 16
camera inputs. Also requires a rear panel card (CM9760-RPC,
CM9760-RPL, CM9760-DFC, or CM9760-DFL).
