INSTALLING YOUR SWITCHER
6
Step 1
. Make sure that the window on the fuse is
set to the proper AC voltage in your
country. An incorrect setting can result in
unit damage, which is not covered by
warranty.
Step 2
. Connect the power cord to the unit and
plug it into the power outlet. Make sure
that the power indicator LED is on.
Step 3
. Connect the cables from the source to the
input connectors and connect display
devices, such as monitors or projectors to
the outputs. Shielded, high quality coaxial
cables are recommended for video cable
runs.
Step 4.
Verify that image on the display is perfect.
The unit will operate successfully as long
as all specifications are followed.
Step 5.
Connect the Rx, Tx, and Gnd signals from
the control system as per section 7.2 if
the
MX2226AT
must be controlled
remotely.
OPERATION
7
7.1 OPERATION FROM THE FRONT PANEL
The front panel of the
MX2226AT
provides access
to essentially all of the switcher’s capabilities. It
has three sections: input select, switcher
functions, and output control.
7.1.2 INPUT SELECT SECTION
SELECTION OF INPUT
:
When the buttons INPUT1 through INPUT6
are pressed, the corresponding INPUT will be
selected. The LED on top of the bottom front
panel will TURN ON simultaneously to indicate
which input has been selected. When
connected as a 1-in 6-out switcher, the outputs
are selected through the INPUT SELECT
section.
SET DEFAULT POWER UP INPUT
:
This function allows a user to define which
input will be selected at power up. To define
the default power on the input channel, while
turning ON the unit, press the desired channel
switch and hold it for approximately 2 seconds
until you hear a short beep. Turn the unit OFF
and then turn it back on again. The LED of the
selected input should be ON. For factory
default the input is set to INPUT1.
7.1.2 SWITCHER FUNCTIONS SECTION
RESET
:
This function allows a user to reset the
switcher without unplugging the unit. Press the
RESET
button
and
hold it for approximately 2
seconds. When you hear a beeping sound,
release the button. All LEDs on the front panel
will flash simultaneously. The
current
connection of input to output will be lost and
power up input will be loaded. The user-set
defaults for SOUND and DEFAULT CHANNEL
will not be changed by the RESET function.
ALL
OFF
:
This function allows a user to turn OFF the
output of the
MX22226AT
. It is very useful
when the
MX2226AT
Switcher is used in an
application, where the display must be blanked
periodically. Press this button to switch to a
“no signal” condition. To resume Input Select
switching, simply press the desired INPUT or
the STEP function.
SOUND
:
This function allows a user to have audible
feedback when the buttons are pressed. The
factory default is set to have audible feedback
ON through to a beep. In some situations
however, sound may be undesirable. To
disable the beeping sound, press this button
and hold it for approximately 2 seconds until a
beep is heard. After the sound is disabled, to
re-enable the sound, repeat the same
procedure.
