SWITCHERS
There are two sections on the front panel of the
MX2456RM: input select and switcher control. The
buttons within the input select section allow for the
actual switching of the source signals. The buttons
within the switcher control section allow access to
the switcher setup features.
4.1. VIDEO SELECT MODE
Default video and audio inputs connect to video
and audio outputs simultaneously, but if needed the
user may select video and audio inputs separately
using AUDIO BREAK AWAY mode. The user can
select any video input by using the input select
buttons located on the front panel.
4.2. AUDIO BREAK AWAY MODE
This mode allows independent selection of video
and audio inputs. After selecting AUDIO BREAK
AWAY mode, the user may select any audio input
for switching when the power is turned ON.
4.3. EQUALIZATION MODE
Video signals are connected from input to output
through a video amplifier along with an equalization
circuit. This allows the user to equalize video
signals for each of the inputs according to the
distance (cable length) from the video source (PC)
to the switcher.
4.4. AUTO SWITCH MODE
If AUTO SWITCH mode is turned ON, the input
which was previously selected by the incoming
video signal will connect to the output
automatically.
If the user does not previously select the AUDIO
BREAK AWAY mode, the same number of audio
inputs will be connected to the audio output.
4.6 AUDIO VOLUME CONTROL MODE
This button allows the user to control the audio
volume using the UP or DOWN buttons. To
increase the volume, push the UP button and to
decrease the volume, push the DOWN button.
4.7. SYNC DELAY MODE
The default SYNC DELAY mode button in the
“OFF” position means that the video portion of the
video signal and the sync portion of the video
signal are connected to the output simultaneously.
The MX2456RM Switcher can operate in SYNC
DELAY mode to avoid a “glitch” effect typically
associated with switching between video sources.
Sync delay time is the amount of time when sync is
connected to the output before the video portion of
the video signal is transmitted. The user may select
a time from 0.5 seconds to 2 seconds.
4.8. BEEP ON/OFF MODE
If the BEEP ON/OFF mode is selected, each
control on the control panel, except the RESET
mode will be without an accompanying beeper
sound.
4.9. RESET MODE
RESET mode sets the memory, which was
previously set by the factory and resets the
Switcher. To reset the switcher, press the RESET
button. In RESET mode, video input 1 and audio
input 1 will be active. AUTO SWITCH mode will be
disabled if previously active. BEEP ON/OFF mode
will return to the ON position if previously in the
OFF position. The RESET mode button does not
affect Audio Volume, Video Equalization, Auto
Rotate or the Sync Delay mode.
4.10 FACTORY RESET MODE
4.5. AUTO ROTATION MODE
The user may select AUTO ROTATION mode with
a preset rotation time. If this mode is selected, then
all video inputs connected to the video output will
be selected alternately. Audio inputs will
simultaneously connect to the audio output along
with video inputs if the user did not previously
select AUDIO BREAK AWAY mode.
This mode clears all data from memory, which was
previously set by the user and returns the switcher
to the factory-preset position. To return the switcher
to the FACTORY PRESET mode, turn OFF the
power, press the RESET button, turn power ON
and then release the RESET button.

INSTALLING YOUR MX2456RM 6
Step 1. Make sure that the power input is set to the
proper AC voltage for the country of usage.
An incorrect setting may result in unit
damage not covered by warranty.
Step 2. Connect the power cord to the unit and
plug it into the power outlet.
Step 3. Connect the cables from the video sources
and the audio sources (computers, VCR,
etc.) to the input channels and connect the
display devices (monitor or projector) and
the appropriate audio equipment (mixer,
amplifier, etc.) to the outputs. For better
results use shielded, high-quality coaxial
cables.
Step 4. Test all the required switching features. If
you experience difficulties or abnormal
switching, you may wish to reset the unit to
the factory defaults to make sure that you
have not entered an incorrect operation
mode. To reset the switcher, turn the
power ON and OFF. Then turn the power
ON again while pressing and holding the
“RESET” button. After a brief delay, all
LED’s should blink ON and OFF. A
beeping sound will be heard several times
indicating that the switcher has been
factory reset.
Step 5. Verify that the display and audio equipment
operates properly and results in perfect
images and sound.
OPERATION 7

7.2.2 PROGRAMMING COMMANDS
NOTE:
These programming commands are used for
programming the switcher; they should not be
used as part of a program to operate the
switcher. The programming setting changes
done through these commands are stored in a
non-volatile memory. Typically, these
commands can be issued 10,000 times before
the memory needs to be replaced.
1. [# SW n1 n2 n3 n4 n5 n6] - Video Switch Input
This is the main command of the video input
Switcher. The [# SW n1 n2 n3 n4 n5 n6]
command contains all the information needed by
the switcher to activate the video sources that
are connected to the unit.
# = Switch number (No. from 1 to 9, Default =
0)
n1 = Video input number (No. from 0 to 6)
n2 = Break Away code (0 = On , 1 = OFF)
n3 = 0 (video key pressed)
n4 = Sync Delay (No. from 0 to 4)
n5 = Video Equalizer (Hexadecimal No. from 0
to F)
The factory default settings is 9600 baud, 8 bits,
1 stop, and no parity. There is no software or
hardware flow control implemented.
The MX2456RM Switcher requires 50ms of
processing time after each command is sent.
So, please keep a 50ms delay between two
consecutive commands.
The RS-232 input has a 16-character buffer and
will not execute any command longer than 16characters. Any additional commands are
ignored until the previous command is fully
processed. After processing a valid command,
an [OK] string will be returned if requested by
the feedback command.
n6 = Audio Gain (Hexadecimal No. from 0 to F)
Example:
Sending the [8SW61040F] command will
activate switcher module 8, video input number 6
and audio input 6. Since the break away code is
1, the zero (0) alerts the switcher that the video
key was pressed. The video key has an interval
of 4 (2 seconds). The video equalizer is OFF,
and the maximum volume is F. Zero means
OFF, and the default is 8 for normal volume or
video.
2. [# SW n1 n2 n3 n4 n5 n6] - Audio Switch Input
This is the main command of the audio input
switcher, which contains all the information
9
Page 11
SWITCHERS
needed by the switcher to activate the audio
sources that are connected to the unit.
# = Switch number (No. from 1 to 9, default = 0)
n1 = Audio input number (No. from 0 to 6)
n2 = Break Away code (0 = On , 1 = OFF)
n3 = 1 (audio key pressed)
n4 = Sync Delay (No. from 0 to 4)
n5 = Video Equalizer (Hexadecimal no. from 1
to F).
n6 = Audio Gain (Hexadecimal no. from 1 to F).
Example:
Sending the [8SW6012F8] command will
activate switcher module 8 and audio input 6
only. Since the break away code is zero (0), 1
alerts the switcher that the audio key was
pressed with an interval of 2 (1 second). The
video equalizer is set to a maximum and a
normal volume of 8 (0 = OFF, default is 8 for
normal volume or video).
3. [#RF] - Factory Reset
This command will replace all settings stored in
the memory of the switcher module. This is
indicated by the factory default settings. All
previous settings will be lost.
Example:
Sending the [8RO] command resets the
switcher module in the Reset Mode with ID
number eight.
5. [# SA n] - Audio Breakaway
This command controls how audio and video
input are selected. The [# SA n] command
allows the user to control audio input and video
input independently or simultaneously.
# = switch number (Default no. is 0)
n = 1 (ON) Breakaway Audio Input from Video
Input and switchers can be activated
independently.
n = 0 (OFF). In this mode the switchers are
activated simultaneously. For example, if
Video Input 2 is pressed Audio Input 2 will
be pressed automatically.
Example:
Sending the [1SA1] command will allow the
user to press Audio Input or the Video Input
independently.
6. [#CSDn] - Sync Delay
This command allows time delay between
switching from one video source to another by
avoiding an overlap of communication problems.
# = switch number (default is 0)
Example:
Sending the command [8RF] command will
reset the Switcher module to the factory settings
with ID number eight.
4. [#RO] - Operation Reset
The [#RO] command will reset audio and video
to input #1, Auto Switch to OFF and Beep OFF
to Beep ON. However, this command will not
affect audio volume, video equalization, auto
rotation, and sync delay.
# = Switch number (Default no. is 0)
# = Switcher module ID number (Default is 0)
n = the time delay interval between video
sources and switching inputs
n = 0 Sync Delay is Off (no delay)
n = 1 0.5 second delay
n = 2 1.0 s
n = 3 1.5 s
n = 4 2.0 s
Example:
Sending the [8CSD4] command sets a 2-second
time delay between input selection of the
connected switcher module with an ID number
of 8.
10
Page 12
SWITCHERS
7. [#Bn] - Beep ON/OFF
This command activates or deactivates the
beeping sound when a key is pressed on the
switcher module.
# = Switcher module ID number (Default is 0)
n = ON/OFF switch
n = 1, turns switcher Beep ON
n = 0, turns switcher Beep OFF
Example:
Sending the [8B1] command sets the beeper to
the ON position in the connected Switcher
module with an ID number of eight.
8. [OASn] - Auto Switch
The [OASn] command sets the switcher module
to the ON position to detect incoming audio or
video signals automatically. Using this
command, the user may also operate the
switcher manually.
n = ON/OFF switch
In addition, by default the switchers still have
an ID number of zero.
10. [#CA n1 n2 ] - Audio Gain Control Save
Settings
This command will save the volume settings for
a specified audio input.
# = Switch number (No. from 1 to 9, Default is 0)
n1 = Audio input number (No. from 0 to 6)
n2 = Audio Gain (Hexadecimal no. from 1 to F).
Example:
After executing the [8CA6F] command,
switcher module 8 and audio input number 6
will have a maximum volume of F (0 = OFF,
default is 8 or normal volume).
11. [#CA n1 n2 ] – Video Equalization Save
Settings
This command saves the settings of the
equalized video signal to compensate for cable
distance from the video source to the switcher.
n = 1 (turns auto switcher ON)
n = 0 (turns auto switcher OFF)
Example:
Sending the [OAS1] command will set the auto
switch feature to the ON position to detect the
incoming video signal automatically.
9. [0I#] - Change Identification Number
This command sets a unique ID number to
each MX2456RM Switcher being used. A
maximum of 9 unit ID’s can be assigned.
0 = Zero
# = New switcher module ID number. (no. from
1 to 9)
Example:
Sending the command [0I8] will reset the active
Switcher module with a new ID number eight.
# = Switch number (Default is 0. No. from 1 to
9).
n1 = Video input number (No. from 0 to 6).
n2 = Video equalization (Hexadecimal no. from
1 to F).
Example:
After executing the [8CA58] command,
switcher module 8 and video input number 5
will have a medium equalization range of 8 (0 =
OFF).
12. [#VR] - Firmware Version
This command displays the firmware revision
number installed into the microprocessor.
# = Switch number (No. from 1 to 9. Default is
0).
11
Page 13
SWITCHERS
Example:
After executing the [8VR] command, the system
will return the version number 8R1.0. If the
user sends the [0VR] command, the system
will return the version number 8R1.0.
If multiple switchers are used, this command
sets a unique ID number for each of the
MX2456RM Switchers. Multiple switcher
modules can be controlled through a single RS 232 port.
In order to control multiple modules
independently with one RS-232 port, the unit ID
must be used. Setting the unit ID allows the
user to send the same command to multiple
modules, but the module processes that
command with the indicated ID number only.
The factory default unit ID is1.
