Connecting the video sources
Connect up to four single link DVI video sources to the Video In ports on the
rear panel using a DVI male to male extension cable. The DVI cable length
is a maximum of 20 ft. (6.1 m).
Connecting the video monitors
Connect up to four DVI video monitors to the Video Out ports on the rear
panel. Monitor cable length is a maximum of 20 ft (6.1 meters).
Note: The UltraMatrix AV 4X4’s learning mode makes it possible to
“learn” the specifications of any monitor connected to output #1,
from the attached computer, or from an Apple monitor.
This enables the unit to emulate a monitor even if none are
attached. This learning feature makes it possible for your
computer/server to boot up even if no monitors are attached.
Connecting the control computer
The controlling computer is used to switch any video source to any video
monitor. These switching commands can be from a serial string sent to the
unit or using RoseControl software to easily route the video.
To connect the control computer to the unit, connect a standard DB9MM
serial cable from a COM port (DB9F) on the control computer to the RS232
port on the UltraMatrix AV 4x4’s rear panel.
