Chapter 1 Introduction

Thank you for purchasing the Moxa UC-8410/8416/8418 RISC-based ready-to-run embedded
computer.

The UC-8410/8416/8418 feature 8 RS-232/422/485 serial ports, 3 10/100 Mbps Ethernet ports,
digital input and digital output channels, switching ports, and CompactFlash and USB ports for
adding additional memory. All of these features make the UC-8410/8416/8418 ideal for your
embedded applications.

This manual introduces the hardware of the UC-8410/8416/8418 embedded computers. After a
brief introduction of the hardware features, we focus on installing and configuring the hardware.

The following topics are covered in this chapter:

UC-8410/8416/8418 Hardware User’s Manual Introduction

Overview

The UC-8410/8416/8418 features 8 RS-232/422/485 serial ports, 3 10/100 Mbps Ethernet ports, 4
digital input channels and 4 digital output channels (12 digital input channels and 12 digital output
channels for the UC-8418), 8 10/100 Mbps swi t ch po rt s (U C -8 41 6 o nly), a CompactFlash slot for
flash disk expansion, and 2 USB ports for adding additional memory (such as a USB flash drive).

The UC-8410/8416/8418 uses an Intel XScale IXP435 533 MHz RISC CPU. Unlike the X86 CPU,
which uses a CISC design, the IXP-425’s RISC design architecture and modern semiconductor
technology provide the UC-8410/8416/8418 with a powerful computing engine and
communication functions, but without generating a lot of heat. The built-in 16 MB NOR Flash
ROM and 256 MB SDRAM give you enough memory to run your application software directly on
the UC-8410/8416/8418. Since the dual LAN ports are built into the IXP435 CPU, the
UC-8410/8416/8418 is good solution for network security applications.

Reset Button

The button labeled Reset returns the UC-8410/8416/8418 to its factory default configuration.
Press the Reset button continuously for at least 5 seconds to load the factory default

configuration. After the factory default configuration has been loaded, the system will reboot
automatically. The Ready LED will blink on and off for the first 5 seconds, and then maintain a
steady glow once the system has rebooted.

We recommend that you only use this function if the software is not working properly and you
want to load factory default settings. To reset an embedded Linux system, always use the software
reboot command />reboot to protect the integrity of data being transmitted or processed.

ATTENTION

Reset button preserves user’s data

The Reset button will NOT format the user directory and erase the user’s data. Pressing the
Reset button will only load the configuration file. All files in the /etc, /home and /tmp
directories will revert to their factory defaults, but other user data will still exist in the Flash
ROM.

Real Time Clock

The UC-8410/8416/8418’s real time clock is powered by a lithium battery. We strongly
recommend that you do not replace the lithium battery without help from a qualified Moxa support
engineer. If you need to change the battery, contact the Moxa RMA service team.

WARNING

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

The two metal brackets that come standard with the UC-8410/8416/8418 are used to attach the
UC-8410/8416/8418 to a wall or the inside of a cabinet. First, use two screws per bracket to attach
the brackets to the bottom of the UC-8410/8416/8418 (Fig. A). Next, use two screws per bracket to
attach the UC-8410/8416/8418 to a wall or cabinet (Fig. B).

An aluminum DIN-Rail attachment plate is included with the product. If you need to reattach the
DIN-Rail attachment plate to the UC-8410/8416/8418, 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

Wiring Requirements

ATTENTION

Safety First!
Be sure to disconnect the power cord before installing and/or wiring your UC-8410/8416/8418.

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 ove rheat, causing serious

damage to your equipment.
Temperature Caution!

Be careful when handling the UC-8410/841 6 / 84 18 . When plugged in, the UC-8410/8416/84 18 ’s
internal components generate heat, and the outer casing may feel hot to the touch.

You should also observe the following common wiring rules:
y 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.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit.

T o a void interference, wires with different signal characteristics should be routed separately.

y You can 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 .

y Keep input wiring and output wiring se parate.
y Where necessary, we strongly recommend that you label wiring to all devices in the system.

Connecting the Power

The UC-8410/8416/8418 has a 3-pin te rminal block for a 12 to 48 VDC power in put .
The following figures show how the power input interface connects to external power source. If

the power is properly supplied, t the Ready LED will illuminate with a solid green color after 30
to 60 seconds have passed.

ATTENTION

The power for this product is intended to be supplied by a Listed Power Supply Unit that is rated
to deliver 12 to 48 VDC at a minimum of 1280 mA for 12 VDC, and 300 mA for 48 VDC.

4-2

UC-8410/8416/8418 Hardware User’s Manual Hardware Connection Description

Grounding the UC-8410/8416/8418

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 devices.

ATTENTION

This product is intended to be mounted to a well-grounded mounting surface, such as a metal
panel.

SG

SG: The Shielded Ground (sometimes called Protected Ground) contact is the

right most contact of the 3-pin power terminal block connector when
viewed from the angle shown here. Connect the SG wire to an appropriate
grounded metal surface.

ATTENTION

A shielded-type power cord is required in order to meet FCC emission limits and also to prevent
interference to nearby radio and television reception. It is essential that only the supplied power
cord be used.

You are cautioned that changes or modifications not expressly approved by the party responsible
for compliance could void your authority to operate the equipment.

Connecting to the Network

Connect one end of the Ethernet cable to one of the UC-8410/8416/8418’s 10/100M Ethernet ports
(8-pin RJ45) and the other end of the cable to the Ethernet network. If the cable is properly
connected, the UC-8410/8416/8418 will indicate a valid connection to the Eth e rnet in the
following ways:

The lower right corner LED indicator maintains a solid
green color when the cable is properly connected to a
100 Mbps Ethernet network. The LED will flash on and
off when Ethernet packets are being transmitted or
received.

81

The lower left corner LED indicator maintains a solid
orange color when the cable is properly connected to a
10 Mbps Ethernet network. The LED will flash on and
off when Ethernet packets are being transmitted or
received.

Connecting to a Serial Device

Use properly wired serial cables to connect the UC-8410/8416/8418 to serial devices. The
UC-8410/8416/8418’s serial ports (P1 to P8) use 8-pin RJ45 connectors. The ports can be
configured by software for RS-232, RS-422, or 2-wire RS-485. The precise pin assignments are
