Real-time Clock
The embedded computer’s real-time clock is powered by a lithium battery. We strongly recommend that you
DO NOT replace the lithium battery on your own. If the battery needs to be changed, contact the Moxa
RMA service team.
ATTENTION
There is a risk of explosion if the wrong type of battery is used. To avoid this potential danger, always be
sure to use the correct type of battery. Contact the Moxa RMA service team if you need to replace your
battery.
Caution
Dispose of used batteries in a suitable manner. Consult the battery manufacturer for details on disposing
batteries.

3. Hardware Connection Description
In this chapter, we show how to connect the embedded computers to the network and to a variety of
common devices.
Installing the V2403C
Wall or Cabinet Mounting
The V2403C comes with two wall-mounting brackets. Use four screws per side to attach the mounting
bracket to the computer. Ensure that the mounting brackets are attached to the V2403C computer in the
direction shown in the following figure.
The eight screws are included in the package. They are standard IMS_M3x5L screws and require a torque of
4.5 kgf-cm. Refer to the following illustration for details.

V2403C Series Hardware User Manual
11
Use two screws (M3*5L standard is recommended) per side to attach the V2403C computer to a wall or a
cabinet. The product package does not include the four screws required for attaching the wall-mounting kit
to the wall; they need to be purchased separately. Ensure that the V2403C computer is installed in the
direction shown in the following figure.
Wiring Requirements
This section describes how to connect peripheral devices to the embedded computer.
You should read and follow these common safety precautions before proceeding with the installation of any
electronic device:
•Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
ATTENTION
Do not run signal or communication wiring together with power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•Use the type of signal transmitted through a wire to determine which wires should be kept separate.
The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
•Keep input wiring and output wiring separate.
•It is advisable to label the wiring to all devices in the system.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your V2403C.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to
your equipment.
Temperature Caution!
Be careful when handling the unit. When the unit is plugged in, the internal components generate heat,
and consequently the outer casing may feel hot to the touch.

Connecting the Power
Connect the 12 to 48 VDC power line with terminal block to the V2403C computer. If the power is supplied
properly, the Ready LED will glow a solid green after a 25 to 30 second delay.

Ignition
The power input specification is given below:
•DC power source rating of 12 V @ 5.83 A; 48 V @ 1.46 A, and a minimum of 18 AWG.
For surge protection, connect the grounding connector located below the power connector with the earth
(ground) or a metal surface.
Grounding the Unit
In addition, a grounding connector is also provided below the power input
connector. Connect the wire to an appropriately
grounded metal surface.

Configuring the Ignition Control Switch
There is an ignition control switch on the front panel of the V2403C. This design helps users to set up the
power ignition time and determine when to trigger the power; it is particularly convenient for the
applications in various transportation industries.
Connecting the Ignition Control Power Input
1. Select a number from 0 to 9 on the switch.
2. Make the following connections:
•
Connect V+ for the system to a 12 to 48 VDC DC
power source
•
Connect the positive line on IGT to a 12 to 24 VDC
power source
•
Connect the negative line on V- to the DC power
sources
Refer to the following table for the detailed switch number and the corresponding power on time and power
