Introduction
Overview
The MOXA UC-7400 Series (herein after referred to as UC-7400) includes UC-7420, UC-7410,
UC-7408, and UC-7402. These RISC-based ready-to-run embedded computers are ideal for
embedded applications. UC-7400 series feature 8 RS-232/422/485 serial ports, dual 10/100 Mbps
Ethernet ports, 8 digital input channels and 8 digital output channels, a PCMCIA interface for
wireless LAN communication, a CompactFlash slot for flash disk expansion, and USB ports for
adding additional memory (such as a USB Flash disk).
The UC-7400 series use an Intel XScale IXP-422 266 MHz RISC CPU. Unlike the X86 CPU,
which uses a CISC design, the IXP-422’s RISC design architecture and modern semiconductor
technology provide UC-7400 with a powerful computing engine and communication functions, but
without generating a lot of heat. The built-in 32 MB NOR Flash ROM and 128 MB SDRAM give
you enough memory to run your application software directly on UC-7400. As the dual LAN ports
are built right into the IXP-422 CPU, UC-7400 makes an ideal communication platform for
Network Security applications. If your application requires placing UC-7400 at a site that is not
located near an Ethernet LAN connection, you can connect to the network by using UC-7400’s
PCMCIA port to attach a wireless LAN card.

UC-7400 Hardware User’s Manual
Reset Button
Introduction
Pressing the Reset button initiates a hardware reboot. The button plays the same role as a desktop
PC’s reset button.
In normal use, you should NOT use the Reset Button. You should only use this function if the
software is not working properly. To reset an embedded linux system, always use the software
reboot command />reboot to protect the integrity of data being transmitted or processed.
Reset to default Button
Press the Reset to default 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. The
Reset to default button is not designed to hard reboot UC-7400.
ATTENTION
Reset to default preserves user’s data
The Reset to default button will NOT format the user directory and erase the user’s data.
Pressing the Reset to default button will only load the configuration file. All files in the /etc
directory will revert to their factory defaults, but other User Data will still exist in the Flash
ROM.
“Reset to Default” is not supported by UC-7420/7410 hardware versions V1.0
The Reset to default button is not supported by UC-7420/7410 hardware version V1.0. You can
identify the hardware version from UC-7420/7410’s lower label. You need to contact MOXA to
determine the product’s hardware version. When contacting our customer support team, you will
need to provide the product’s Serial Number (S/N) that is found on UC-7420/7410’s lower label.
Real Time Clock
UC-7400’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 MOXA RMA service team.

Introduction
Hardware Connection Description
This section describes how to connect UC-7420/7410 to serial devices for first time testing
purposes. We cover Wiring Requirements, Connecting the Power, Grounding UC-7400,
Connecting to the Network, Connecting to a Serial Device, Connecting to the Console Port,
PCMCIA, CompactFlash, USB, and DI/DO.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your UC-7400.
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 UC-7400. When plugged in, UC-7400’s internal components generate
heat, and consequently 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. To avoid 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
y
Keep input wiring and output wiring separate.
Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting the Power
Connect the 12 to 48 VDC power line with UC-7400’s terminal block. If the power is properly
supplied, the Ready LED will illuminate with a solid green color after 30 to 60 seconds have
passed.
Grounding UC-7400
Grounding and wire routing helps 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.

Introduction
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface, such as a metal
panel.
SG: The Shielded Ground (sometimes called Protected Ground) contact is
the left 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.
Connecting to the Network
Connect one end of the Ethernet cable to one of UC-7400’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,
UC-7420/7410 will indicate a valid connection to the Ethernet in the following ways:
