Chapter 1 Introduction

The V481 is an industrial, ready-to-run embedded computer that supports VGA and audio. The
computer comes with dual LAN ports, 8 serial ports, 2 CompactFlash slots, and 2 USB ports, and
is based on the Intel x86 processor. With its VGA interface, the V481 is especially well suited for
industrial applications, such as SCADA, factory automation, and other applications that require an
onsite HMI or visual monitoring capability.

The V481’s 8 built-in, software-selectable RS-232/422/485 serial ports makes it an ideal solution
for connecting to different devices. The dual LAN ports offer a reliable solution for network
redundancy by providing continuous operation for data communication and management. In
addition, the second CompactFlash socket makes it easier to add storage space, and the USB ports
can connect to a wide range of devices, making the V481 a reliable embedded computer for
industrial applications that require VGA and HMI features.

The V481 comes pre-installed with the Windows CE 5.0 or Windows XP Embedded operating
system, providing programmers with a friendly environment for developing application software.
V481 programmers have an added advantage in that Moxa provides good software support to
reduce the cost and time required for software development.

In this chapter, we cover the following topics:

Overview

The V481 Series of x86 ready-to-run embedded computers is designed around the Intel Celeron M
1 GHz processor. In addition to the usual computer peripherals, the V481 integrates one 10/100
LAN port, one Gigabit LAN port and 8 RS-232/422/485 serial ports, making the V481 into an
ideal industrial embedded computer for handling industrial communication applications that need
to connect to a monitor or HMI onsite.

The on-board CompactFlash and DDR SDRAM provide ample storage capacity, and the second
CompactFlash socket allows users to install additional memory.

The Windows-based operating system comes pre-installed and ready-to-run, providing a
Windows-like environment for easy software development. Software written for desktop PCs can
be easily ported to the V481 using a common complier, which means that programmers do not
need to spend a lot of time modifying existing software code. In addition, the operating system,
device drivers, and user-developed software can all be stored in the pre-installed CompactFlash
memory Card.

Power On/Off Button

The power on/off button is located above the power input terminal block. The button supports the
ATX power on/off function. By default, the button is set for “instant off.” You may also configure
the button for “delay 4 seconds” to guard against shutting down the power unintentiona lly. In this
case, you must press the power button continuously for at least 4 seconds to shut off the power.
For detailed configuration instructions, please see “Chapter 4: BIOS Setup” towards the end of this
manual.

Reset Button

Pressing the Reset button initiates a hardware warm reboot. The button plays the same role as a
desktop PC’s reset button. After pressing the reset button, the system will reboot automatically.

During normal use, you should NOT use the Reset Button. You should only use this button if the
software is not working properly. To protect the integrity of data being transmitted or processed,
you should always reset the system from the operating system with the software reboot function.

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, please 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 when you
need to replace the battery.

Placement Options

Wall or Cabinet

The V481 has wall-mount ears for attaching the V481 to a wall or the inside of a cabinet. Use
screws to attach the V481 to a wall or cabinet, as illustrated in the following figure.

DIN-Rail Mounting

An aluminum DIN-Rail Mounting Kit is included with the V481. If you need to reattach the
DIN-Rail kit to the V481, make sure the stiff metal spring is situated towards the top, as shown in
the following figures.

STEP 1: Insert the top of the DIN-Rail
into the slot just below the stiff metal
spring.

STEP 2: The DIN-Rail attachment
unit will snap into place as shown
below.
