Panel Mounting
A panel-mounting kit consisting of 8 mounting units is provided in the
MPC-2120 package. For details on the dimensions and the cabinet space
required to panel mount the MPC-2120, refer to the following illustration:
To install the panel-mounting kit on the MPC-2120, place the mounting
units in the holes provided on the rear panel and push the units to the left
as shown in the illustration below:

Use a torque of 4Kgf-cm to secure the mounting screws to fasten the
panel-mounting kit onto the wall.
VESA Mounting
The MPC-2120 is provided with VESA-mounting holes on the back panel,
which you can use directly without the need for an adapter. The
dimension of the VESA mounting area is 50 mm x 75 mm. You will require
four 6-mm M4 screws to VESA mount the MPC-2120.

Display-Control Buttons
The MPC-2120 is provided with two display-control buttons on the right
panel.
The display-control buttons can be used as described in the following
table:

ATTENTION
The
MPC-2120 comes with a 1000-nit display, the brightness
level of which is adjustable up to level 10. The display is
optimized for use in the
-40 to 70°C temperature range.
However, if you are operating the
MPC-2120 at an ambient
temperature of 60°C or higher, we recommend setting the
brightness
level of the display to 8 or lower in order to
extend the
lifetime of the display.

Connector Description
DC Power Input
The
MPC-2120 uses a DC power input. To
connect the power source
to the 2-
pin terminal
block
, use a 60 W power adapter. The
terminal
-block connector for the power input
is
available in the
accessories package. The DC
pin assignments are as shown in the figure.
Serial Ports
The MPC-2120 offers two software-selectable RS-232/422/485 serial
ports over a DB9 connector. The pin assignments for the ports are shown
in the table below:

DIO Port
The MPC-2120 is provided with a DIO port, which is a 10-pin terminal
block that includes 4 DIs and 4 DOs as illustrated in the following
diagram.
Installing a CFast or SD Card
MPC-2120 provides two storage options—CFast and SD card. The storage
slots are located on the left panel. You can install the OS on the CFast card
and save your data into the SD card. For a list of compatible CFast models,
check the MPC-2120 component compatibility report available on Moxa’s
website.
To install the storage devices, do the following:
1. Remove the 2 screws holding the storage-slot cover to the MPC-2120.

- 8 -
2. Insert the CFast or SD card into the slot using the push-push
mechanism.
3. Reattach the cover and secure it with screws.
Real-Time Clock
The real-time clock (RTC) is powered by a lithium battery. We strongly
recommend that you do not replace the lithium battery without help from
a qualified Moxa support engineer. If you need to change the battery,
contact the Moxa RMA service team. The contact details are available at:
http://www.moxa.com/rma/about_rma.aspx.
ATTENTION
There is a risk of explosion if the clock’s lithium battery is
replaced with an incompatible battery.
Powering On/Off the MPC-2120
Connect a Terminal Block to Power Jack Converter to the MPC-2120
terminal block and connect a 60 W power adapter to the converter.
Supply power through the power adapter. After you have connected a
power source, the system power turns on automatically. It takes about 10
to 30 seconds for the system to boot up. You can change the power-on
behavior of your computer by changing the BIOS settings.
To power off the MPC-2120, we recommend using the "shut down"
function provided by the OS installed on the MPC. If you use the Power
button, you may enter one of the following states depending on the power
management settings in the OS: standby, hibernation, or system
shutdown mode. If you encounter problems, you can press and hold the
Power button for 4 seconds to force a hard shutdown of the system.

Grounding the MPC-2120
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.
