ABOUT YOUR MX2436RM 2
The MX2436RM is Video and Audio Switcher
designed to handle the switching requirements of
several multimedia applications.
The MX2436RM offers six BNC inputs with ground
loop isolation, which promote individual equalization
of video gain according to different cable lengths.
Each of the BNC inputs can be connected to a
single BNC output. The MX2436RM also provides
six stereo or balanced audio inputs, which can be
connected to a single stereo or balanced audio
output.
The MX2436RM allows the non-simultaneous
connection of six video sources to a monitor or
projector and six audio sources to any audio system.
In addition, the MX2436RM is controllable using its
built-in front panel or through RS-232.
Using optional hardware, the MX2436RM can be
rack mounted alone as a single unit or two units can
be rack-mounted side by side.

There are two sections on the front panel of the
MX2436RM: 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 choosing AUDIO BREAK
AWAY mode the user may select any audio input
for switching when the power is turned ON.
4.3. EQUALIZATION MODE
With video signals connected from input to output
through a video amplifier along with an equalization
circuit, the user can 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 automatically connect to the
output.
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.
4.5. 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.
4.6 AUDIO VOLUME CONTROL
This feature 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. VERTICAL INTERVAL SWITCHING MODE
The VERTICAL INTERVAL SWITCHING mode will
be activated automatically if the house sync BNC
connector is connected to the house sync source or
composite video is connected to Input 1. If House
Sync is not connected and the Composite Video
signal is present on Input 1, then the vertical
interval switching process will be controlled by
Vertical Sync from the composite video signal.
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 for the MX2436RM
Switcher. To reset the switcher, press the RESET
button. In the 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
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 Reset mode, turn OFF the power,
press the Reset button, turn power ON and then
release the Reset button.

step represents 0.8dB. After selecting the
volume, press and hold the UP and DOWN
buttons simultaneously.
8. To turn “OFF” the beeping sound, press and
hold the “BEEP ON/OFF” button. The LED,
which represents this button, should turn OFF.
To activate sound, press and hold the “BEEP
ON/OFF” button again.
9. To return the switcher to factory preset, press
the “RESET” button. After a brief delay, all LED’s
should blink ON and OFF. A beeper will sound
several times indicating that the switcher has
been reset.
7.2 RS-232 CONTROL OF THE SWITCHER
The MX2436RM Switcher offers remote control
capabilities through RS-232. RS-232 is the primary
communication standard used by control systems
and computers.
In fact, the MX2436RM offers more features using
RS-232 than are currently available from the front
panel of the unit.
The MX2436RM offers a terminal block using
solder-free, screw-down contacts, making it
extremely easy to connect the switcher to a control
system or a computer in the field.

4XMT (Transmit)
Table 4. Pin Designations.
The terminal block is labeled with the appropriate
contact designations: Transmit (XMT), Receive
(RCV), and Ground (GND). Always remember that
the Transmit pin from the control system or
computer must be connected to the Receive pin on
the control port of the switcher; do not connect
Transmit to Transmit or Receive to Receive.
Note: the contact labeled +5V is not used for
RS-232 connections. This contact provides DC
voltage to other equipment installed within close
proximity of the MX2436RM.
Typically, a control system or computer will offer
RS-232 connections on a 9-pin D connector.
The following are typical cable pin-out designations
for RS-232 connections on a 9-pin D connector.
Always verify that the pin-outs for your system are

7.2.1 RS-232 PROTOCOL:
The RS-232 protocol for the MX2436RM
Switcher uses a simple ASCII character format.
1. Square brackets “[“ & “]” are part of the
command.
2. Use uppercase letters for all commands.
3. Make sure that the transmit pin of the
control system is connected to the
receive pin of the switcher and
connection done as per Table 4.
4. Make sure that there is a delay of 50 ms
between two consecutive commands.
The factory default settings is 2400 baud, 8 bits, 1
stop, and no parity. There is no software or
hardware flow control implemented.
The MX2436RM 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 16-
characters. 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.
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 program 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
#= Switch number (no. from 1 to 9; default is
0).
n1 = Video input number (no. from 0 to 6)
n2 = Break Away code (0 = On; 1 = OFF)
n3 = 0, video key pressed
n4 = 0 Sync Delay. TheMX2436RM
Switcher is equal to zero. It is not
necessary for the switch to delay.
n5 = Video Equalizer (Hexadecimal no. from
0 to F).
n6 = Audio Gain (Hexadecimal no. from 0 to
F).
The [# SW n1 n2 n3 n4 n5 n6] command is the
main command of the video input switcher
containing all the information needed by the
switcher to activate the video sources
connected to the unit.
Example:
Sending the [8SW61040F] command will
activate switcher module 8, Video Input number
6 and Audio Input 6(because the breakaway
code is 1). The zero (0) will notify the switcher
that the video key was pressed with an interval
of 4 (2seconds). The video equalizer was set to
OFF and there is a maximum volume of F.Zero
(0) = OFF and default is 8 for a normal volume
or video).

2. [# SW n1 n2 n3 n4 n5 n6] - Audio Switch
Input
# = Switch number (no. from 1 to 9; default is
0).
n1 = Audio input number (no. from 0 to 6).
n2 = Break Away code: (0 = On; 1 = OFF)
n3 = 1, audio key pressed
n4 = 0, Sync Delay. TheMX2436RM Switcher
is equal to zero. It is not necessary for
the switch to delay.
n5 = Video Equalizer (Hexadecimal no. from 1
to F).
n6 = Audio Gain (Hexadecimal no. from 1 to F).
This is the main command of the audio input
switcher containing all the information needed
by the switcher to activate the audio sources
connected to the unit.
Example:
Sending the [8SW6012F8] command will
activate switcher module 8and audio input
number 6 only (because the breakawaycode is
0). The “1” will let the switcher know that the
audio key was pressed with and interval of2 (1
second), video equalizer was set to a maximum
and a normal volume of 8.Zero (0) = OFF and
default is 8 for normal volume or video).
3. [#RF] - Factory Reset
#= Switch number (default is 0)
This command will replace all the previously
stored settings in the memory of the switcher
module, which is indicated by the factory default
setting. Note that previously stored settings will
be lost.
Example:
Sending the [8RF] command resets the
Switcher module with ID number eight to the
factory settings.
4. [#RO] - Operation Reset
#= Switch number (default is 0)
This command will reset the following:
•Audio and Video is set to input #1
•Auto Switch is set to the OFF position
•Beep is set to the ON position
The following will not be affected:
•Audio Volume
•Video Equalization
•Auto Rotate
•Sync Delay
Example:
Sending the [8RO] command resets the
Switcher module with ID number eight to the
Reset Mode.
5. [# SA n] - Audio Breakaway
# = Switch number (default is 0)
n= 1 (ON) Audio Breakaway, Audio Input
Video Input and switchers can be
activated separately.
n = 0 (OFF) In this mode the switchers are
activated simultaneously. For example, if
Video Input 2 is pressed, Audio Input 2 will
be automatically activated.
This command controls audio and video input
numbers that will be sent simultaneously or
separately allowing the control of Audio input
and the video input independently.
Example:
Sending the command [1SA1] will allow the
user to select independently Audio Input from
Video Input.
Sync Delay
The MX2436RM Switcher is equal to zero.
Therefore, it is not necessary for the switch to
delay.

SWITCHERS
11
6. [#Bn] - Beep ON/OFF
# = Switcher module ID number (default is 0)
n = ON/OFF switch
n = 1 (Turns switcher Beep ON)
n= 0 (Turns switcher Beep OFF)
This command activates or deactivates the
beeping sound when a key is pressed on the
switcher module.
Example:
Sending the command [8B1] set the beeper ON
in the connected Switcher module with ID
number eight.
7. [OASn] - Auto Switch
n= ON/OFF switch
n= 1 (Turns auto switcher ON)
n= 0 (Turns auto switcher OFF)
The [OASn] command sets the switcher
module to the ON position to auto detect the
incoming audio or video signals or OFF to
operate it manually or with a PC software.
Example:
Sending the [OAS1] command will set the auto
switch feature to the ON position, which will
automatically detect the incoming video signal.
8. [0I#] - Change Identification Number
0= Zero
# = New Switcher module ID number (no.
from 1 to 9).
This command sets a unique ID number to each
MX2436RM Switcher module. A total of 9 unit
ID’s can be assigned.
Example:
Sending the command [0I8] will reset the active
Switcher module with the new ID number eight.
In addition, by default the switcher still has ID
number zero.
9. [#CA n1 n2 ] - Audio Gain Control Save
Settings
#= Switch number (default is 0; no. from 1
to 9).
n1 = Audio input number (no. from 0 to 6).
n2 = Audio Gain (Hexadecimal no. from 1 to
F).
The [#CA n1 n2 ] command will save the
volume settings for a specified audio input.
Example:
After the [8CA6F] command has been
executed, switcher module 8and Audio Input
number 6will have a maximum volume of F (0
= OFF, default is 8 or normal volume).
10. [#CA n1 n2 ] – Video Equalization Save
Settings
#= 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).
This command saves the settings of equalized
video signals to compensate for cable lengths
from the video source to the switcher.
Example:
When sending the [8CA58] command, Switcher
module 8and Video Input number 5will have a
medium equalization range of 8 (0 = OFF).
11. [#VR] - Firmware Version
This command displays the firmware revision
number that is installed into the microprocessor.
#= Switch number (default is 0; no. from 1 to
9).
Example:
When sending the [8VR] command the system
will return the version number 8R1.0.When
sending the [0VR] command the system will
return the version number 8R1.0.

SWITCHERS
12
This command sets a unique ID number to each
MX2436RM Switcher module and allows control
of multiple modules through a single RS-232
port.
In order to control multiple modules
independently with one RS-232 port, the unit ID
is used. Setting the unit ID allows a 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=1.

through RS-232 or through
the control panel.
4. Why is sync
delay
switching
useful?
It eliminates the glitch
normally associated with
switching between high-
resolution RGB type
sources. This is
accomplishing by
disconnecting the sync
portion of a signal before
the incoming video–making
the glitch takes place off-
screen. The Sync Delay
feature is only designed to
work with RGBS and
RGBHV signal formats.
5. Can the
MX2436RM
Switcher be
used outside
of the United
States?
Yes, the MX2436RM uses a
universal internal power
supply, enabling it to be
used throughout the world.
Please make sure to use
the proper adapter cable for
the country in which it will
be used. Adapter cables for
several countries are
available through ALTINEX.
