Can the
MX2226AT
be used to
pass
Composite
Video,
S-Video, and
Component
Video?
Yes, simply use the
corresponding channels to
pass the signals (e.g. For
composite video, you may
use the red channel or you
may use the blue channel).
Since the
MX2226AT
is a
relay switcher, it can be
used as a contact closure
control or to switch virtually
to any type of video, sync,
audio, or even RS-232
signals.
4
What is the
difference
between the
VIDEO OFF
button and
the ALL OFF
button?
When the ALL OFF button
is pressed none of the
inputs is connected by the
MX2226AT
, while the
VIDEO OFF button disables
the video portion of the
selected input but continues
to send the sync portion of
the signal.
5
Can I use
contact
closures to
control the
MX2226AT
?
No, the
MX2226AT
is not
designed for control
through contact closures at
this time. To use contact
closures you may consider
using the ALTINEX
CP7317RS
Controller to
convert contact closures to
RS- 232 commands.
6
Can the
MX2226AT
Switcher be
used outside
of the United
States?
Yes, the
MX2226AT
uses a
universal internal power
supply, enabling it to be
used throughout the world.
First, make sure that you
have the voltage setting in
the correct position, and
second make sure to use
the proper adapter cable for
the country where it will be
used. Adapter cables for
several countries are
available through ALTINEX
as listed in section 9.

How do I
control several
You cannot control multiple
MX2226AT
Switchers
switchers
independently
with one RS-
232 card in a
control
system?
independently with one RS-
232 control card at this
time. The unit does not
have user-selectable ID
codes or command
delimiters. So, a command
sent by a control card
cannot be interpreted
individually by each switch.
If this is a required feature,
the units can be pre-set at
the factory for individual ID
codes. Please call
ALTINEX at 1-714-990-
2300 for details.
8
Does the
”Loop”
connection on
the 4 pin
Terminal
Block allow
me to loop
RS-232 to
another
switcher?
No, the ”Loop” feature on
this connector allows
multiple switchers to be
connected and operated as
one large switcher with
more than six inputs. For
the solution to this, see the
Master/Slave control
operations section, 7.5.
9
Why doesn’t
my control
system work
when I have
the sync
Delay feature
activated?
The Sync Delay feature
requires 2.5 seconds to be
executed. You must make
sure that your control
system of at least 2.5
seconds allows for the
delay between two
consecutive commands.
