Overview
The UC-8410A computer comes with various communication interfaces, which make it an ideal communication
platform for industrial applications. The communication interfaces include eight RS-232/422/485 serial ports,
three 10/100/1000 Mbps Ethernet ports, four digital input and four digital output channels, and a wireless
communication slot (not available in the –NW model). In addition, the UC-8410A is provided with an mSATA
slot for storage expansion, and 2 USB ports for additional memory (such as a USB flash drive). The computer
is built using a NXP Cortex-A7 dual-core 1 GHz RISC CPU. This powerful computing engine supports several
useful communication functions, but will not generate too much heat. The computer's built-in 8 GB eMMC and
1 GB DDR3 SDRAM give you sufficient memory to run your application software while the SD slot and mSATA
socket provide you the flexibility to expand the data storage capacity.

ATTENTION
Reset
button preserves user data
The
Reset button will NOT format the user directory or erase the user data. Pressing the Reset button
continuously for at least 5 seconds
will only load the configuration file. For the Linux OS, 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. For the Windows CE 6.0 OS, all registry configurations will revert to the factory default.
Real-time Clock
The UC-8410A’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
of battery.

Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord befo
re installing and/or wiring your UC-8410A.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
that
dictate the maximum current allowed for each wire size. If the current goes above the ma
ximum ratings,
the wiring could overheat, causing serious damage to your equipment.
Temperature Caution!
Be careful when handling the
UC-8410A. When plugged in, the UC-8410A’s internal components generate
heat, and the outer casing may feel hot to the touc
h.
You should also observe the following common wiring rules:
•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.
•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.
•Keep input wiring and output wiring separate.
•We strongly recommend that you label wiring to all devices in the system for easy identification.
Connecting the Power
The UC-8410A has a 3-pin terminal block for a 12 to 48 VDC power input.
The following figures show how the power input interface connects to an external power source. If the power
is properly supplied, the Ready LED will illuminate 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 1
010 mA for 12 VDC, and 240 mA for 48 VDC.
Grounding the UC-8410A
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.

UC-8410A HW UM Hardware Connection Description
4-3
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.
An additional ground connector is provided just above the power
block,
which
you can use for additional grounding protection.
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
power cord supplied w
ith the unit is used
to supply power
.
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-8410A’s 10/100/1000 Mbps Ethernet ports (8-pin RJ45)
and the other end of the cable to the Ethernet network. If the cable is properly connected, the UC-8410A will
indicate a valid connection to the Ethernet 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.

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-8410A to serial devices. The UC-8410A’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 shown in the following table:

Installing the SD Card and mSATA Card
The UC-8410A comes with a SD card slot and an mSATA socket for storage expansion. To replace or install the
SD card, or to install an mSATA card, follow these steps:
1. Use a screwdriver to remove the screws on the rear and side panels of the cover over the mSATA socket.
2. Remove the cover to access the SD-card slot and the mSATA socket.
3. Push the SD card in gently to release it and remove the SD card to insert a new one in the socket.
4. Insert the mSATA card into the socket and fasten the screws.
NOTE
The mSATA card is NOT included in the product package and must be purchased separately. All standard
mSATA card types have been tested with the UC-8410A computer and have been found to work normally.
USB
The UC-8410A has 2 USB 2.0 hosts for external storage expansion. The USB hosts are located on the front
panel.
