Bottom View-2-Panel Mounting
A panel-mounting kit consisting of 8 mounting units is provided in theMPC-2120 package. For details on the dimensions and the cabinet spacerequired 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:-3-Use a torque of 4Kgf-cm to secure the mounting screws to fasten thepanel-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. Thedimension 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.

-4-Display-Control Buttons
The MPC-2120 is provided with two display-control buttons on the rightpanel.

The display-control buttons can be used as described in the following

ATTENTION
The MPC-2120 comes with a 1000-nit display, the brightnesslevel 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 thebrightness level of the display to 8 or lower in order to extend thelifetime of the display.

DC Power Input
The MPC-2120 uses a DC power input. Toconnect the power source to the 2-pin terminal
block, use a 60 W power adapter. Theterminal-block connector for the power input isavailable 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 shownin the table below:

USB Ports
Two USB 2.0 ports are available on the bottom panel. Use these ports toconnect mass-storage drives and other peripherals.

-6-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 cardand save your data into the SD card. For a list of compatible CFast models,
check the MPC-2120 component compatibility report available on Moxa’swebsite.
To install the storage devices, do the following:
1.

Remove the 2 screws holding the storage-slot cover to the MPC-2120.

2.

Insert the CFast or SD card into the slot using the push-pushmechanism.

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 froma 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 apower 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 Powerbutton, 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 thePower button for 4 seconds to force a hard shutdown of the system.

-8-Grounding the MPC-2120
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.
