8-out V-MATRIX™ Video/Sync Output Cards
The VM2144VS/VM2145SS/VM2146UX are 8-
output Cards designed for use in a V-Matrix™
enclosure and can handle a wide array of signal
formats and connector types. When installed in a
V-Matrix™ Basic Enclosure, these Output cards
enable the connection of eight composite sources
when used with the VM2143VS 8-in Video/Sync
Input Card. See the VM2143VS for more
information.
The VM2144VS/VM2145SS 8-output video/sync
cards provide built-in ground loop isolation (GLI on
Board™) through the use of differential inputs. This
is an extremely important feature because it
protects against hum bars and other interference
caused by ground loops, which notoriously wreak
havoc on large-scale matrix systems. Both the
input and output video cards provide a bandwidth
of 350 MHz @ –3dB, allowing them to pass
extremely high-resolution computer video/sync
signals without signal degradation.
The VM2145SS has a negative and positive
polarity. It can be used as sync output by setting its
jumpers to the appropriate position.
The VM2146UX is 8-output Universal Card that can
process video and sync output signals. See jumper
settings for sync and video output for more
information.
All input and output cards are “hot-swappable” with
finger adjustable lock-down screws and secure,
positive engagement card-edge connections.
