Panel Mounting
The MD-219 comes with 14 optional clamp mounts for installation
on a wall (where space has been cut out to accommodate the rest
of the hardware) or into computing stations where a flush mount is
desired. The maximum thickness of the surface to which the
display will be clamped is 11 mm. For a secure mounting, all 14
clamps must be used. The clamp arms are fastened into slots on all
four sides of the MD-219. Use the short M4 SUS screws to fasten
the clamp arms to the MD-219 mounting slots, as shown in the
magnified inset in the diagram just below. Next, use the clamps to
fasten the display to its mounting point; note the torque value
shown in the figure inset below.
VESA Mounting
The MD-219 also comes with an optional VESA mounting kit. Six
flat screws and four round screws are required to fasten the VESA
mounting bracket. See the figure below for detailed screw
specifications and torque values.
An additional four screws (not included in the kit) are required to
mount the display on a VESA rack. For this purpose, use M6 screws
with a length between 10 and 12 mm.
Connector Description
Extending the Display
The MD-219 comes with both standard VGA and DVI-D interfaces
on the bottom panel. It will automatically detect whether the input
video source is from the VGA or DVI-D interface.
Configuring the Display via the Serial Port
The MD-219 has two serial ports. The RS-232 port uses a DB9
connector, 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. Refer to the MD-219 User’s
Manual for serial port configuration details. The pin assignments
for the ports are shown in the following table:

Powering on/off the MD-219
To power on the MD-219, connect to an AC power source, a DC
power source, or both. Touch the MENU button for 1 second to turn
on the display. Touch the MENU button for 4 seconds to turn off the
display.
NOTE If only one power input is being connected, the INFO button
will be red. This will not affect the functionality and
performance of MD-219 as long as the power input is
stable.
Grounding the MD-219 Series
Proper grounding and wire routing help to limit the effects of noise
from electromagnetic interference (EMI). Run the ground
connection from the ground screw to the grounding surface prior to
connecting the power source.
For detailed configuration of the MD-219, refer to the MD-219
Series User’s Manual.
