V481-CE

Quick Installation Guide

Second Edition, April 2008

1. Overview

The V481 is an industrial, ready-to-run embedded computer that supports
VGA and audio, and comes with dual LAN ports, 8 serial ports, a
CompactFlash slot, and a USB port. The V481 is based on the Intel x86
processor. The VGA interface makes the V481 especially well-suited for
industrial applications, such as SCADA, factory automation, and
applications that require an onsite HMI or monitor.

4. Installing the V481

Wall or Cabinet Mounting

The V481 has built-in “ears” for attaching the embedded computers to a
wall or the inside of a cabinet. We suggest using two scr e ws per ear to
attach the V481 to a wall or cabinet.

DIN-Rail Mounting

An aluminum DIN-Rail mounting kit is a standard accessory. If you need
to reattach the DIN-Rail mounting kit to the V481, make sure the stiff
metal spring is situated towards the top, as shown in the following figures.
Follow Steps 1 and 2 to mount the V481 on the DIN-Rail.

STEP1: Insert the top of the
DIN-Rail into the slot just below
the stiff metal spring.

STEP2: The DIN-Rail attachment
unit will snap into place as shown.

5. Connector Description

Power Connector

Connect the 9 to 36 VDC LPS or Class 2 power line to the V481’s
terminal block. If the power is properly supplied, the Power LED will
light up.

Grounding the V481

Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw 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.

SO-DIMM Socket for Memory Module

The V481 has an internal 200-pin SO-DIMM socket for installing a DDR
SDRAM memory module. The V481 comes with a 256 MB DDR
SDRAM Module pre-installed. You may also replace the module with
your own (128 MB to 1 GB) DDR SDRAM memory module. To replace
the module, first remove the bottom cover of the V481 to expose the
SO-DIMM socket.

Compact Flash Socket

The V481-CE comes with a built-in 256 MB industrial CompactFlash
card to store the WinCE 5.0 operating system. A second CompactFlash
socket is located inside the V481. Installing a second CompactFlash
memory card will not affect the operating system. Remove the bottom
cover of the V481 to install the second CompactFlash card.

USB Hosts

The V481 supports two USB 2.0 hosts. Both hosts are UHCI, Rev. 2.0
compliant and support Plug & Play and also hot swapping. Both hosts can
be used to connect any USB device, such as a keyboard, mouse, USB
flash disk, or USB CD-ROM. In addition, both USB ports support system
boot up, which is activated by changing BIOS settings.

Audio Interface

The V481 has an audio interface that
follows the AC97 standard and
supports speaker output and audio
line input.

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
unintentionally. In this case, you must press the power button
continuously for at least 4 seconds to shut off the power.

Reset Button

The reset button is designed to warm reboot the V481. 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 rest button, the system
will reboot automatically. During normal use, you should NOT use the
Reset Button. You should only press the Reset Button if the software is
not working properly. To reset the system, work from the operating
system environment by using the corresponding software reboot function
to protect the integrity of data being transmitted or processed.

Real-time Clock

The embedded computer’s real-time clock is powered by a lithium battery.
We strongly recommend that you NOT replace the lithium battery
yourself. If the battery needs to be changed, please contact the Moxa

RMA service team.
ATTENTION

There is a risk of explosion if the battery is replaced by an incorrect type
of battery.

6. Powering on the V481

To power on the V481, connect the “termi nal block to power jack
converter” to the V481’s DC terminal block (located on the left rear
panel), and then connect the power adapter. Note that the Shielded
Ground wire should be connected to the right most pin of the terminal
block. It takes about 30 seconds for the system to boot up.

7. Starting the V48 1

Power on the V481 after connecting a monitor, keyboard, mouse, and
checking that the power source is ready.

Once the operating system boots up, the first step is to configure the
Ethernet interface. The factory default settings for the V481’s dual LANs
are shown below. You can use a cross-over Ethernet cable to connect
directly from the PC to the V481 to test if the LAN settings are correct.

Default IP Address Netmask

LAN 1

192.168.3.127 255.255.255.0

LAN 2 (Gigabit)

192.168.4.127 255.255.255.0

8. Configuring the Ethernet Interface

Follow these steps to configure the Ethernet interface:
Step 1: Go to [Start] Æ [Settings] Æ [Network and Dial-Up

Connections]. You will see two network interfaces.
Step 2: Right-Click the LAN interface (e.g., PCI\E100CE1) to

configure and click property. A configuration window will
pop up.

Step 3: After inputting the proper IP address and netmask, click OK.
