MP168 Matrix Switcher/Controller System
DESCRIPTION
Video Input Module 4
The MP168 Video Input Module 4 (VIM-4) is used for
both standard switching and looping applications where
signals from video sources are passed through the VIM-
4 to dedicated video output devices.
Each VIM-4 has two Coaxial cable connectors labeled
IN (video from a loop panel) and OUT (video to a
suitable video output processing device or to the input
of a VIM-4 module in a dual bay configuration).
In single bay systems, one loop panel receives video
input signals from cameras and similar devices and
routes them via ribbon cable to the IN connector of the
VIM-4 module. A loop panel receives the video signals
from the OUT connector of the VIM-4 and routes the
signal to suitable video output devices such as monitors
and recorders.
In dual bay systems, a loop panel is used in conjunction
with cabled pairs of VIM-4 modules (one module per
bay). Ribbon cables route the signals between the bays
and the loop panel.
NOTE: A cabled pair is two modules, each located in a
separate bay, joined by a ribbon cable.
