General
The MX-2003B Dual-View Video Processor 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 simultaneously in Picture-In-Picture (PIP) or
Picture-Aside-Picture (PAP) modes. The MX-2003B allows you to manipulate output images, wherever position
and whatever sizes you want for viewing two computers or two video signals or a combination.
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.

Inputs and Outputs
The MX-2003B has four inputs and accepts both graphics and video signals, which come from computers
and NTSC/PAL video sources respectively. There is a concept of main channel and sub channel for this device.
You can pick up two of the four inputs, one is for main channel and the other is for sub channel, and then display
two of them simultaneously on the same screen. Figure 2 shows the rear panel connectors of a MX-2003B and
Table 1 illustrates how you can connect video devices and display to the MX-2003B.

7. DIP switch* (for firmware & system reset)
*Default: Turn on the MX-2003B then switch both two DIP switches simultaneously up and down
to factory default mode.
*These IO ports support various resolution from 640x480 up to 1920x1200, for more detail of
the supported modes, please refer to the Appendix –Supported Resolution.

Safety Precautions
I. To prevent fire or shock hazards, do not expose this device to rain or moisture.
II. When connecting other products such as DVD players, and personal computers, you should turn off the
power of this product for protection against electric shocks.
III. The product should be placed more than one foot away from heat sources such as radiators, heat registers,
stoves, and other products (including amplifiers) that produce heat. In addition, do not cover any material or
devices on the top of the device.
IV. Do not use immediately after moving from a low temperature to high temperature, as this causes
condensation.
V. Do not place this product on an unstable cart, stand, or table. The product may fall, causing serious injury to
a child or adult and serious damage to the product.
VI. Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use
a damp cloth for cleaning.
VII. Do not allow the same still picture to be projected for a long time or an abnormally bright video picture to be
projected. The video image could be burned in to the display device.
Installation Procedures
Unpacking
Remove the MX-2003B from the shipping container and examine it for any signs of shipping damage or
missing items (check with package contents above). All shipping items should be saved if the product is to be
moved or returned for service. Shipping unit back to dealers for service not in the original box may result in

(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 MX-2003B.
7. Connect a device equipped with composite video output to composite input of the MX-2003B.
8. Connect your computer with the MX-2003B by a 9-pin RS-232 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.
11. Press down arrow key dropping down sub-menu to select the first channel (Main Channel) video/graphic
source.
12. Once the Main Channel has a video selected, press “exit” key to exit the sub-menu, and then move right to

System Requirement and Precautions
1. The MX-1003B provides a software control program which runs under Microsoft Windows 98, 2000, XP
through the interface of RS-232 serial control.
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-1003B and switched on the MX-1003B with green LED light.
3. The MX-1003B 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-1003B
after you press any key on the remote control.
Instruction of Software Connection
1. Power up the MX-1003B and you can see both red and green LEDs on the front panel blink. Make sure the
serial port (RS-232) connection secure.
2. The first step after running the software is to automatically detect if the device responses correctly through
RS-232 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-1003B is not supplied with power or the MX-1003B enters deep sleep state. Please check the current
status, and reboot the MX-1003B
The serial connection through RS-232 is not well established or some other software has taken the available
serial ports. Please make sure the RS-232 cable is well connected and the available serial port is free to be used
by the MX-1003B.
Operation Software
