MT105-120/121 Re-Configurable
VGA-QXGA Video Matrix Switcher Cards
The MT105-120/121 are VGA-UXGA Video Matrix
Switcher Cards designed to switch 150 MHz high
bandwidth RGBHV video signals. The MT105-120
card has eight fixed inputs and eight fixed outputs
with 15-pin HD connectors. The MT105-121 card
has eight fixed inputs and four fixed outputs, also
with 15-pin HD connectors.
Both cards provide signal detection on input and
output through horizontal SYNC. This feature
allows for easy remote diagnostics throughout
RS-232 commands, from the source all the way to
the output connectors.
The MT105-120/121 provides an economical
application due to the space saving design by
using
D-connectors instead of BNC connectors.
Inputs are switched to outputs through easy-to-use
ASCII commands from a control system or
computer connected to the RS-232 port of the
Multi-Tasker enclosure. Both cards allow muting
audio output through RS-232 commands. Inputs
and outputs may be programmed in batches and
switched all at the same time with a single
command.
Used in combination with MT110-100 and
MT110-101 Audio Matrix Switcher cards, it is
possible to group audio and video inputs and
outputs to be switched as audio and video or
independently.
A special feature of the MT105-120/121 is Sync
Delay to eliminate the appearance of video signals
before the display device is able to process the
sync signals and properly format the video image.
The Sync Delay is the amount of time to wait after
switching the Horizontal and Vertical Sync signals
and before switching the RGB signals. Each output
may be programmed with a delay ranging from
zero to 24.75 seconds, in increments of 250mS.
