INTRODUCTION
The MX-2000A Dual-View Video Processor with Audio Path is an advanced video processor for
multimedia presentations. It is an ideal solution for applications where two video signals must be
displayed on a single display. It supports up to four video inputs, of which two can be outputted simultane-
ously in Picture-In-Picture (PIP) or Picture-Aside-Picture (PAP) modes. The MX-2000A allows you to
manipulate output images, wherever position and whatever sizes you want for viewing two computers or
two video signals or a combination. Despite the advanced video features, MX-2000A also equips audio
processor allowing users to do analog switching and convert analog stereo into HDMI streams.
The embedded scaler converts signals from input sources to match the native resolution of monitors,
flat panel displays, projectors as well as user-selectable output settings up to WUXGA (1920x1200). Dual
outputs are provided in both analog (VGA) and digital (HDMI/DVI) format, one is connected to remote
display and the other is connected to on-site display for real time monitoring.

DVI and VGA respectively by a DVI to DVI/VGA breakout cable (DDVY01)) .
3. Plug in DVI to DVI/VGAbreakout cable (DDVY01) to DVI-IN and plug in VGA to component breakout
cable (VYPBA01) to the VGA connector of the breakout cable.
4. Connect a device equipped with DVI output (such as PC) to the DVI connector of the breakout cable.
5. Connect a device equipped with component video output (YPbPr such as DVD player or camera) to
the 3-RCA jack of the VYPBA01.
6. Connect a device equipped with VGA output (such as laptop) to the VGA connector of the
MX-2000A.
7. Connect a device equipped with composite video output to composite input of the MX-2000A.
8. Connect your computer with the MX-2000A by a Mini USB cable and then install the software.
9. Plug in power adapter cable into 5V DC power jack.
10.Switch on all devices connected and then switch on the video processor and then press “menu” to
display OSD menu.

OPERATION SOFTWARE
System Requirement and Precautions
1. The MX-2000A provides a software control program which runs under Microsoft Windows 98, 2000,
XP through the interface of USB interface.
2. Before you click on the icon of the software, make sure you have secured the connection between
your computer COM port and the MX-2000A, also switched on the MX-2000A with green LED light.
3. The MX-2000A has remote control and software control. To make sure all information shown in the
software is synchronized with those in the device, please click “Connect” to acquire the latest data
from the MX-2000A after you press any key on the remote control.
Instruction of Software Connection
1. Power up the MX-2000A and you can see both red and green LEDs on the front panel blink. Make
sure the serial port USB connection secure.
2. The first step after running the software is to automatically detect if the device responses correctly
through USB port. The process takes 15-20 seconds. If the response is not accurate, a warning
window will show up as the figure below.
The possible reasons causing this failure could be:
●The MX-2000A is not supplied with power or the MX-2000A enters deep sleep state. Please
check the current status, and reboot the MX-2000A.
●The serial connection through USB is not well established or some other software has
taken the available serial ports. Please make sure the USB cable is well connected and the
available serial port is free to be used by the MX-2000A.
●Com setting is not correct. Please make sure that from Menu→ Connector→ Setting.

TROUBLESHOOTING
Problem
Recommendations
No power
Check if you are using 5V DC adapter and it is firmly plugged into the
MX-2000A
If you are recovering from power outage, accidentally unplug the adapter
or other power surge conditions, leave the device off for a while and then
power it on again.
No/ Erratic video
Make sure all cables are in good working condition and properly
connected to the MX-2000Aand displays.
Configure the output video resolution so that it doesn’t excess the native
resolution of the display. ( in this case, the message of “out of range” is
usually showed on your screen)
Make sure a video source is selected to the main channel. (press “Menu”
and check if the first item has a video source selected or press “Source”
to select a video source for the main channel)
Poor quality
We suggest that don’t use T-connectors to split your video source into to
images displayed on two different screens. That will lower output video
quality. Use a distribution amplifier instead of T-connectors.
Make sure the video source is not compressed and maintains the highest
native resolution.
Image position shifted
Press “Auto” key on the remote control.
Wrong color
Press “Color” key for auto color configuration.
Auto color configuration only works at VGA and component inputs.
Auto color configuration only works at VGA and component inputs.
