Installing the V2403C
The V2403C computer comes with two wall-mounting brackets. Attach the brackets to the computer using four screws on each side. Ensure that the mounting brackets are attached to the V2403C computer in the direction shown in the following figure.
The eight screws for the mounting brackets are included in the product package. They are standard IMS_M3x5L screws and require a torque of 4.5 kg-cm. Refer to the following illustration for details.
Use two screws (M3*5L standard is recommended) on each side to attach the V2403C to a wall or 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.
Connecting the Power
The V2403C computers are provided with 3-pin power input connectors in a terminal block on the front panel. Connect the power cord wires to the connectors and then tighten the connectors. Push the power button.
The Power LED (on the power button) will light up to indicate that power is being supplied to the computer. It should take about 30 to 60 seconds for the operating system to complete the boot-up process.
| Pin 1 | Definition |
| 1 | V+ |
| 2 | V- |
| 3 | Ignition |
The power input specification is given below:
• The DC power source rating is 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.
In addition, there is an ignition control switch on the front panel, which can be used to control the power input. Refer to the V2403C Hardware User’s Manual for details.
Connecting Displays
The V2403C has 1 display port connector on the rear panel. In addition, another HDMI interface is also provided on the rear panel.
NOTE In order to have highly reliable video streaming, use premium HDMI-certified cables.
USB Ports
The V2403C comes with 4 USB 3.0 ports on the front panel. The USB ports can be used to connect to other peripherals, such as keyboard, mouse, or flash drives for expanding the system’s storage capacity.
Serial Ports
The V2403C comes with 4 software-selectable RS-232/422/485 serial ports on the rear panel. The ports use DB9 male connectors. Refer to the following table for pin assignments:
| Pin | RS-232 | RS-422 | RS-485 (4-wire) |
RS-485 (2-wire) |
| 1 | DCD | TDA(-) | TDA(-) | |

Installing Storage Disks
The V2403C comes with two 2.5-inch storage sockets, allowing users to install two disks for data storage.
Follow these steps to install a hard disk drive.
- Unpack the storage disk tray
- Place the disk drive on the tray. from the product package.
- Turn the disk and tray arrangement around to view the rear side of the tray. Fasten the four screws to secure the disk to the tray.
- Remove all screws on the rear panel of the V2403C computer.
- Take out the rear cover of the computer and find the location of the storage disk sockets. There are two sockets for the storage disk tray; you may install them on either socket.
- To place the storage disk tray, put the end of the tray near the groove on the socket.
- Place the tray on the socket and push upward so that the connectors on the storage disk tray and the socket can be connected. Fasten two screws on the bottom of the tray.
For instructions on installing other peripheral devices or wireless modules, refer to the V2403C Hardware User’s Manual.
NOTE This computer is intended to be installed in a restricted access area only. In addition, for safety reasons, the computer should be installed and handled only by qualified nd experienced professionals.

NOTE If using a Class I adapter, the power cord adapter should be connected to a socket outlet with an earthing connection or the power cord and adapter must comply with Class II construction.
Replacing the Battery
The V2403C comes with one slot for a battery, which is installed with a lithium battery with 3 V/195 mAh specifications. To replace the battery, follow the steps below:
- The battery cover is located on the rear panel of the computer.
- Unfasten the two screws on the battery cover.
- Take off the cover; the battery is attached to the cover.
- Separate the connector and remove the two screws on the metal plate.
- Replace the new battery in the battery holder, place the metal plate on the battery, and fasten the two screws tightly.

NOTE • Be sure to use the correct type of battery. The incorrect battery may cause system damage. Contact Moxa’s technical support staff for assistance, if necessary.
• To reduce the risk of fire or burns, do not disassemble, crush, or puncture the battery; do not dispose of it in fire or water, and do not short external contacts.
ATTENTION
Before connecting the V2403C to the DC power inputs, make sure the DC power source voltage is stable.
The wiring for the input terminal block shall be installed by a skilled person.
• Wire type: Cu
• Only use 28-18 AWG wire size and a torque value of 0.5 Nm.
• Use only one conductor in a clamping point between the DC power source and the power input.
