Installing the Mini-PCIe Modules and USIM Cards
ATTENTION
Select
“-W” models (e.g., V2403-C2-W-T) when placing V2403
order
s for wireless applications. Moxa will add 3 mini-PCIe
sockets during production. Note that
the internal storage kit
cannot be used with
“-W” models. To expand the storage of “-W
”
models, use an mSATA card.

2. Locate the screw holes on the bottom of the V2403.
3. Place the brackets on the bottom of the V2403 and align the screw
holes on the brackets with the screw holes on the V2403.
4. Insert and tighten the screws into the screw holes.
NOTE
Use all eight screws to ensure that the V2403 is safely and
securely installed on the DIN rail.
5. When the brackets are firmly attached with the screws, you can
install the V2403 onto a DIN-rail.

To remove the V2403 from the DIN-rail, first use a screwdriver to pull
down the DIN-rail connector to unlock it.
To re-install the V2403 on the DIN-rail, use a screwdriver to press the
buckle so that it can be released. At this point, it can be re-installed on the
DIN-rail.
Wall or Cabinet Mounting

Connector Description
Power Connector
Connect the 9 to 36 VDC LPS or Class 2 power line to the V2403’s terminal
block. If the power is supplied properly, the Power LED will light up. The
OS is ready when the Ready LED glows a solid green.
Grounding the V2403
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
grounding screw (M4) to the grounding surface prior to connecting the
power.
ATTENTION
This product is intended to be mounted to a well
-grounded
mounting surface, such as a metal panel.
DVI-I Outputs
The V2403 comes with 1 DVI-I female connector for the DVI display. This
output interface is located on the front panel of the product. Be sure to
use the correct cable to connect the computer to the display.
HDMI Outputs
The V2403 comes with a type A HDMI female connector and a DVI-I
female connector on the front panel to connect an HDMI or DVI-I
supported monitor.
The screw hole above the HDMI connector is used to attach a customized
lock to the HDMI connector; a custom lock is needed since the shape of
different HDMI connectors are not the same. Please contact a Moxa sales
representative for details.
The lock appears as shown below:
The lock should appear as shown here after it is
