DESCRIPTION
MP168 Matrix Switcher/Control System
VIDEO INPUT MODULES
•
The MP168 VIM-4 module is used in single
and dual bay applications. VIM-4 modules are
used in conjunction with external Looping
Panels to route video signals into, through, and
out of the MP168 Bay. VIM-4 modules may
reside in slots A through O.
The MP168 Video Input Modules (VIMs) function by
recognizing the presence of a video signal and then
switching the signal to the Central Processing Unit.
Then, the video is switched to the appropriate Video
Output Module.
All video inputs to the MP168 system are connected to
the application specific VIM Rear Panels (see Figure 1-
6B). The VIM card receives switching instructions
from user keyboards, GUIs, and external systems with
the appropriate protocol.
In the MP168 Switching System, there are four types of
Video Input Modules (VIM-1, VIM-2, VIM-3, and
VIM-4). The Circuit Cards in all four VIM modules
are identical, only the Rear Panel Assemblies differ,
according to their intended function.

The front and rear sections of all MP168 VIM
modules are identified with a BLUE color
code dot affixed to the respective section.
Each MP168 Video Input Module includes the
following components:
VIM Circuit Card
VIM Rear Panel Assembly consisting of:
Application Specific Rear Panel and Rear
Panel Circuit Card
An MP168 VIM-1 module provides 12 direct
input channels for video sources. The MP168
Bay supports a maximum of 15 VIM-1
modules. VIM-1 modules can reside in slots A
through O determined by the letter slot
screening on the front and rear bay surface
(see Figure 1-6A).
• MP168 VIM-2 and VIM-3 modules are used
in dual bay applications. Installed in pairs and
joined by ribbon cables, VIM-2/VIM-3
module pairs provide 12 direct input channels
(6 per module) for video sources. VIM-
2/VIM-3 pairs can reside in slots A through O.
