1 Introduction
Congratulations on purchasing your OMX-SW5x5 5x5 Video Audio Matrix
Switcher, which comes with a power cord
1
, a Null-modem adapter, a
Windows®-based control software, an Infra-red remote control transmitter
and this instruction manual.
The OMX-SW5x5 is ideal for the following typical applications:
 Professional display systems requiring true 5x5 matrix operation
 Multimedia and presentation source and acceptor selection, and remote
monitoring of computer activity in schools and businesses
2 Getting Started
We recommend that you:
 Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
 Review the contents of this user manual
1 We recommend that you use only the power cord that is supplied with this machine

Overview

3 Overview
The OMX-SW5x5 is a true 5x5 matrix switcher for composite video signals
and balanced stereo audio signals. The high quality OMX-SW5x5 lets you
simultaneously route any or all of the 5 inputs to any or all of the 5 outputs.
The OMX-SW5x5 5x5 Video Audio Matrix Switcher includes:
 A Video bandwidth of 70MHz that ensures transparent performance
 Easy-to-connect detachable terminal block connectors for the audio
signals
 Glitch-free transitions, which are produced when sources share a common
reference sync, as switching occurs during the vertical interval
1
. Any input or
special external sync input may be selected as the vertical interval source
 DC coupled inputs and outputs
 Audio-follow-video and breakaway options
 Storing and recalling setups
 “Take” button for precise switch control
 “Lock” button to prevent tampering with the front panel
 Gain control for all inputs and all outputs
 The ability to control via the front panel buttons, via the Infra-red remote
control transmitter, and remotely by RS-485 or RS-232 serial commands
transmitted by a touch screen system, PC, or other serial controller
To achieve the best performance:
 Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise-
levels (often associated with low quality cables)
 Avoid interference from neighboring electrical appliances and position
your OMX-SW5x5 away from moisture, excessive sunlight and dust
4 Your OMX-SW5x5 Video Audio Matrix Switcher
Figure 1, Figure 2, Table 1 and Table 2 define the OMX-SW5x5 Video Audio
Matrix Switcher:
1 When one video signal replaces another video signal, the switching process causes a random interruption in the first video
signal (in the middle of a frame) and a random entrance into the second video signal (also in the middle of a frame). The
result is a visible jump in the edited tape. This deteriorates when the tape is copied, and the disturbance on playback is more
serious. Avoid this by switching at a very specific point during the vertical interval, allowing smooth replacement of a whole
frame by a second whole frame as long as the video sources are Genlocked to each other

5 Installing on a Rack
This section describes what to do before installing on a rack (see section 5.1)
and how to install on a rack (see section 5.2).
5.1 Before Installing on a Rack
Before installing the machine in a 19" rack, be sure that the environment is
within the recommended range:
Table 3: Recommended Ambient Temperature and Humidity Range
Operating temperature range +5 to +45 Deg. Centigrade
Operating humidity range 5 to 65 % RHL, non-condensing
Storage temperature range -20 to +70 Deg. Centigrade
Storage humidity range 5 to 95% RHL, non-condensing
5.1.1 CAUTION!!
When installing the OMX-SW5x5 in a 19" rack, avoid hazards by taking care
that:
1. It is located within the recommended environmental conditions, as the
operating ambient temperature of a closed or multi-unit rack assembly may
exceed the room ambient temperature.
2. Once rack-mounted, enough air will still flow around the machine.
3. The machine is placed straight in the correct horizontal position.
4. You do not overload the circuit(s). When connecting the machine to the
supply circuit, overloading the circuits might have a detrimental effect on
overcurrent protection and supply wiring. Refer to the appropriate nameplate
ratings for information. For example, for fuse replacement, see the value
printed on the product label.
5. The machine is earthed (grounded) in a reliable way and is connected only to
an electricity socket with grounding. Pay particular attention to supply
connections other than direct connections to the branch circuit (for example,
the use of power strips), and that you use only the power cord that is supplied
with the machine.
5.2 Instructions for Rack-Mounting
To install the OMX-SW5x5 in a 19" rack, place the ears of the machine
against the rack rails, and insert the screws through each of the four holes in
the rack ears
1
.
1 Always mount the machine in the rack before you attach any cables or connect the machine to the power

to:
 Connect the OMX-SW5x5 rear panel (see section 6.1)
 Control via RS-232, for example, using a PC (see section 6.2)
 Control via RS-485 (see section 6.3)
 Connect the audio inputs/outputs (see section 6.4)
 Set the dipswitches (see section 6.5)
6.1 Connecting the OMX-SW5x5 Rear Panel
To connect the OMX-SW5x5, do the following
1
:
1. Connect up to 5 composite video sources
2
to the 5 BNC input connectors, and
connect
3
up to 5 balanced stereo audio sources
4
to the “AUDIO INPUTS”
terminal block connectors.
2. Connect
5
the 5 composite video output connectors to up to 5 composite video
acceptors
2
and connect the corresponding “AUDIO OUTPUTS” terminal
block connectors to the balanced stereo audio acceptors
4
.
3. Set the dipswitches (see section 6.5).
4. Connect a PC and/or controller (if required) to the RS-232 port (see section 
6.2) and/or RS-485 port (see section 6.3).
5. Connect
4
the power cord
6
.
1 Switch OFF the power on each device before connecting it to your OMX-SW5x5. After connecting your OMX-SW5x5,
switch on its power and then switch on the power on each device.
2 For example, VCR machines
3 See section 6.4 for a description of how to connect a balanced/unbalanced stereo audio input/output
4 Not illustrated in Figure 3
5 When less than five outputs are required, connect only those outputs of the OMX-SW5x5 that are required, and leave the
other outputs unconnected
6 We recommend that you use only the power cord that is supplied with this machine
