Installing the UC-8100A-ME-T
DIN-rail Mounting
The aluminum DIN-rail attachment plate is already attached to the
product’s casing. To mount the UC-8100A-ME-T on to a DIN rail, make
sure that the stiff metal spring is facing upwards and follow these steps.
1. Pull down the bottom slider
of the DIN-rail bracket
located at the back of the
unit
2. Insert the top of the DIN rail
into the slot just below the
upper hook of the DIN-rail
bracket.
3. Latch the unit firmly on to
the DIN rail as shown in the
illustrations below.
4. Push the slider back into
place.

Wall Mounting (Optional)
The UC-8100A-ME-T can be mounted with a wall-mounting kit that needs
to be purchased separately. Follow these steps to mount the computer on
to a wall:
Step 1
Use four screws to fasten the
wall-mounting brackets on the
left panel of the computer.
Step 2
Use another four screws to mount
the computer on a wall or a
cabinet.
Connector Description
Power Connector
Connect the power jack (in the package) to the UC-8100A-ME-T’s DC
terminal block (located on the top panel), and then connect the power
adapter. It takes about 30 seconds for the system to boot up. Once the
system is ready, the Power LED will light up.
Grounding the UC-8100A-ME-T
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI).
SG:
The Shielded Ground (sometimes called
Protected Ground) contact is the top 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.
Ethernet Ports
The two 10/100 Mbps Ethernet ports (LAN 1 and LAN 2) use RJ45
connectors.

SD/SIM Card Sockets
The UC-8100A-ME-T comes with an SD socket for storage expansion, and
a SIM card socket for cellular communication. The SD card/SIM card
sockets are located at the lower part on the front panel. To install the
cards, remove the screw and the protection cover to access the sockets,
and then insert the SD card or the SIM card into the sockets directly. You
will hear a click when the cards are in place. To remove the cards, push
the cards in before releasing them.
Console Port
The console port is an RS-232 port that can be connected to with a 4-pin
pin header cable. You can use this port for debugging or firmware
upgrade.

Real-time Clock
The real-time clock in the UC-8100A-ME-T is powered by a lithium battery.
We strongly recommend that you do not replace the lithium battery
without the help of a Moxa support engineer. If you need to change the
battery, contact the Moxa RMA service team.
ATTENTION
There is a risk of explosion if the battery is replaced with an
incorrect type of battery.
Accessing the UC-8100A-ME-T Using a PC
You can use a PC to access the UC-8100A-ME-T by one of the following
methods:
A. Through the serial console port with the following settings:
Baudrate=115200 bps, Parity=None, Data bits=8, Stop bits =1,
Flow Control=None
ATTENTION
Remember to choose the “VT100” terminal type. Use the console
cable to connect a PC to the UC-8100A-ME-T's serial console port
