ABOUT YOUR SWITCHER 2
MX2106AV
2-In, 2-Out VGA+3.5mm AUDIO
Auto-Switcher
The MX2106AV is a 2-In, 2-Out VGA + 3.5mm
AUDIO Auto-Switcher. The MX2106AV
automatically switches on signal detection, but may
also be controlled manually if desired. The
MX2106AV is designed to switch VGA signals and
stereo audio.
The unit is encased in a solid metal enclosure and
ships with an external, 9V 500mA, power adapter.
Override switching is made through the INPUT
SELECT/RS-232 input. Manual override switching
is made via a contact closure on the INPUT
SELECT jack. This switch may be used for manual
control, or the contact closure may be controlled
from a control system. RS-232 control is
accomplished by sending ASCII commands to
select either Input 1 or Input 2.

APPLICATION DIAGRAM 5
DIAGRAM 1: TYPICAL CONFIGURATION
In addition to automatic switching, the MX2106AV may be controlled manually with an external switch, or using
ASCII commands over the RS-232 bus.
If a remote switch is connected to the INPUT SELECT jack, INPUT 1 will be selected when the contact is open.
INPUT 2 will be selected if the channel select contact is closed. If the RS-232 cable is connected, the user may
send the command [ON1] to select input 1 or [ON2] to select input 2.
Auto-switching is disabled with either manual or RS-232 control. The switching will be identical whether there
are one or two active signals. The indicator lights located next to the input ports indicate which input is selected.

INSTALLING YOUR SWITCHER 6
Step 1. Make sure that the correct power adapter
is used. The Altinex power adapter is
supplied with the unit. Connect the power
adapter to the power port. The INPUT 2
indicator light should be ON and GREEN.
NOTE: INPUT 2 is the default if there is
no signal on INPUT 1.
Step 2. Connect the VGA source or sources to
the MX2106AV inputs. If there is a
properly formatted input signal on Input 1,
the switcher will switch Input 1 to the
outputs automatically.
Step 3. Connect a cable from one or both of the
output ports on the MX2106AV to display
devices.
Step 4. If a remote switch or RS-232 control is to
be used, connect the control cable to the
INPUT SELECT/RS-232 port. See
Section7 for specific control functions.
NOTE: See Figure 1below for cabling
information. The INPUT SELECT/RS-232
port receives a 3.5mm Stereo Plug.
Step 5. Verify that the picture quality on the
display is good. If a signal is not being
received, make sure that the display is
compatible with the resolution of the
computer graphics card.

OPERATION 7
There are no settings to adjust on the MX2106AV
Auto-Switcher. The MX2106AV will operate
successfully as long as cables are attached
properly and other specifications are followed.
AUTO-SWITCH MODE
The MX2106AV automatically selects INPUT 2 if no
active signals present. If a signal is on INPUT 2 and
not on INPUT 1, the MX2106AV will maintain
INPUT 2. However, when an active signal is
applied to INPUT 1, the MX2106AV will switch to
INPUT 1. If active signals are on both inputs, the
MX2106AV will automatically switch to INPUT 1.
MANUAL SWITCH MODE
Manual override is accomplished via a contact
closure on the INPUT SELECT/RS-232 jack.
Manual Switch Mode disables Auto-Switching.
This switch may be used for manual control, or the
contact closure may be made from a control
system.
INPUT 1 will be selected when the remote control
switch is connected to the INPUT SELECT jack and
the contact is open. INPUT 2 will be selected if the
contact is closed.
RS-232 SWITCH MODE
The MX2106AV may be switched using simple
ASCII commands through standard RS-232
communication. Connect the RS-232 cable to the
INPUT SELECT/RS-232 jack. In RS-232 Control
Mode, Auto-Switching is disabled. Send the
following commands over the RS-232 bus to select
the desired input.
[ON1] = Select INPUT 1
[ON2] = Select INPUT 2
NOTE: The "[" and "]" brackets are part of the
command and must be included.
CABLE/ACCESSORIES
Cable accessories for RS-232 Control and Remote
switching are available from Altinex.

TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no
problems in the supplied MX2106AV unit. However,
we would like to offer the following suggestions:
8.1 LEDs ARE OFF
Cause 1: The power adapter is installed
wrong.
Solution 1: Make sure the adapter output is
connected to the POWER input jack
on the unit. If one of the LEDs is still
not on, see Solution 2.
Solution 2: Ensure the adapter is plugged into
an AC outlet that has power. If the
adapter has AC power and the LEDs
are still off, see Cause 2.
Cause 2: The wrong power adapter is
installed.
Solution 1: Please use the Altinex supplied
external adapter (9V, 500mA). If one
of the LEDs is still not on, please call
ALTINEX at [phone].
8.2 UNIT DOES NOT AUTO-SWITCH
Cause 1: The manual override switch is
installed.
Solution: Remove the connection to the
INPUT SELECT jack on the unit. If a
plug is installed in the jack, even
without a switch, the unit will not
auto-switch properly. If the unit does
not auto-switch with the plug
removed, see Cause 2.
Cause 2: The signal is not active or is
improperly formatted.
Solution 1: Remove the input signals from the
switcher. If the IN 2 LED is OFF, call
ALTINEX at [phone]. If the
IN 2 LED is ON, see Solution 2.
Solution 2: Connect a properly formatted VGA
type signal from to INPUT 1. If the
switcher does not switch to INPUT
1, see Solution 3.
Solution 3: Bypass the switcher and connect the
output of the source directly to the
display. If the display is good, then
call ALTINEX at [phone].
8.3 NO DISPLAY
Cause 1: The source has a problem.
Solution: Check the source and make sure
that there is a signal present and all
source connections are correct. If
the source is working and there is
still no display, see Cause 2.
Cause 2: Manual override is ON.
Solution: Make sure there is nothing
connected to the INPUT SELECT
port on the switcher. If there is
nothing connected, see Cause 3.
Cause 3: Signal is bad or missing.
Solution 1: Make sure the switcher output is
connected to the monitor. If there is
still no display, see Solution 2.
Solution 2: Remove both inputs to the switcher
and connect the active signal form
the source to INPUT 2. If there is still
no display, see Solution 3.
Solution 3: Bypass the switcher and connect the
output of the source directly to the
monitor. If the display is good, then
call ALTINEX at [phone]. If
there is still no display, see Cause 4.
Cause 4: Cable connections are incorrect.
Solution: Make sure the cables are properly
connected. Also, make sure that the
continuity and wiring are good. If
there is still no display present, see
Cause 5.
Cause 5: The display has a problem.
Solution: Make sure the display has power
and is turned ON. If there is still no
display, please call Altinex at
[phone].
