SPECIFICATIONS

The OMX-4x4 Switchers are flawlessly designed 4 x 4 matrix routers for seamless routing between an y one
of four inputs to any or all of the four outputs.

Since audio-follows-video, each switch selected controls

both video and audio. As a true matrix switcher, you may send any input signal to any output.
Vertical Interval Switching provides glitch free transitions between synchronized sources.
The 4x4 models are controlled from the front panel using “output” assignment switches with LED con-

firm. Additionally, a 9-Pin Serial Control Port Located on the rear panel is provided to interface y our PC
with the switcher. Included Software is provided for switcher control from any standard PC.

BASIC OPERATIONS

POWER UP After unpacking the unit, plug in to 110 VAC power. The OMX-4X4 has no

power switch. The front panel LEDs will light immediately. After a second the
LEDs will go out. This indicates that POWER RESET has occurred and that the
microprocessor is operational.

CONNECTIONS Connect the composite video to input #1.THIS INPUT MUST BE USED AT ALL

TIMES. Failure to use video input #1 will disable the switcher. Connect other
video sources to inputs 2-4 as desired. The OMX-4X4 comes factory set for
video 75Ω termination. If the OMX-4X4 is to be bridged with another device or
another OMX-4X4, then the internal termination switches must be set to “off” as
required. Open the top panel and set the 4 position DIP Switch located near
the front, to the proper termination. OFF is open and ON is terminated. There
is no need for audio termination.

Connect the outputs using the proper cables to the various destinations in your
system. All output cables must be properly terminated if the devices being fed
these signals provide a terminate option.

OPERATION Once the unit is properly connected, simply select the input required to be

switched for each output. The front panel switches are labeled “OUTPUT” on
the top of the switch area and “INPUT” below the switches. To select input #1
to be fed to output #2: Simply push the #1 button for output #2 switch buss.

RS-232 RS-232 oper ation requires that y ou first write a program that outputs HEX code

via the COM port of your PC. Review the section: SERIAL PROTOCOL in this
manual for additional programming information.

You can control the OMX-4X4 with the PC software control provided with this
unit. You can also order a more sophisticated software.
VERSION 1.0 is provided with this manual. Review the installation instructions
later in this manual.
