Installing the MD-200 Series
DesktopThe MD-200 series comes with optional brackets that allow you to installthe display on a horizontal surface, such as a desktop. Three roundscrews are required for each bracket. See the figure for detailed screw
specifications and their torque values.
Place your MD-200 series display on a clean, flat, well-ventilated desktop.
To protect the computer from overheating, leave some ventilation space
between the MD-200 series and other equipment.
Do NOT place equipment or objects on the panel, as this might damage
internal components.
-3-Panel Mounting
The MD-200 series comes with 14 optional clamp mounts for installation
on a wall (where space has been cut out to accommodate the rest of thehardware) or into computing stations where a flush mount is desired.
The maximum thickness of the surface to which the computer can
be clamped is 11 mm. For a secure mounting, all 14 clamps must beused.
The clamp arms are fastened into slots on all four sides of the MD-200series. Use the short M4 SUS screws to fasten the clamp arms to theMD-200 series mounting slots, as shown in the following magnified inset
in the diagram. Next, use the clamps to fasten the MD-200 series to itsmounting point; please note the torque value as shown in the figure.

-4-VESA Mounting
The MD-200 series also comes with an optional VESA mounting kit. Sixflat screws and four round screws are required to fasten the VESA
mounting bracket. See the following figure for detailed screw
specifications and torque values.

An additional four screws (not included in the kit) are required to mountthe display on a VESA rack. For this purpose, use M6 screws that are
between 10 and 12 mm in length.

Connector Description
Extending the Display
The MD-200 series comes with both standard VGA and DVI-D interfaces
on the bottom panel. It automatically detects whether the input video
source is from the VGA or DVI-D interface.
Configuring the Display via the Serial Port
The MD-200 series has two serial ports. The RS-232 port uses a DB9connector, and the RS-422/485 port uses a terminal block connector.
Either serial port can be used to modify the display parameters using
UART commands. For information on serial port configuration, see theMD-200 Series Hardware Manual.

a DC power source, or both. Touch the MENU button for 1 second to turnon the display. Touch the MENU button for 4 seconds to turn off thedisplay.

Grounding the MD-200 Series
Proper grounding and wire routing help to limit the effects of noise fromelectromagnetic interference (EMI). Run the ground connection from theground screw to the grounding surface prior to connecting the powersource.
For detailed configuration of the MD-200 Series, refer to the MD-200
