Overview
The UC-8100 computing platform is designed for embedded
data-acquisition applications. The computer comes with one or two
RS-232/422/485 serial ports and dual 10/100 Mbps Ethernet LAN ports,
as well as a Mini PCIe socket to support cellular modules. These versatile
communication capabilities let users efficiently adapt the UC-8100 to a
variety of complex communication solutions.

Installing the UC-8100
There are two sliders on the back of the unit for DIN-rail and wall
mounting.
Mounting on a DIN Rail
Pull out the bottom slider, latch the unit onto the DIN rail, and push the
slider back in.
Mounting on a Wall
Pull out both the top and bottom
sliders,
align the screws with the
mounting holes, and secure the
dev
ice to the wall by driving the
screws into the wall
.
Another method for wall mounting installation is to use the optional wall
mounting kit. Attach two mounting brackets on the side panel of the
computer, and fasten with screws. Install the computer on to a wall or
cabinet by fastening two screws for each mounting bracket.
Connector Description
Power Connector
Connect the “terminal block to power jack converter” (included in the
package) to the UC-8100’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-8100
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI).
SG:
The s
hielded
ground (sometimes called
p
rotected 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.
ATTENTION
The product is intended to be supplied by an UL Listed power
adapter whose output meets SELV/LPS, and is rated 12
-
24 VDC,
minimum 0.5 A, Tma = 85°C (minimum).
Ethernet Ports
The two 10/100 Mbps Ethernet ports (LAN 1 and LAN 2) use RJ45
connectors. Refer to the following table for the pin assignments.

SD/SIM Card Slots
The UC-8100 comes with an SD slot for storage expansion and a SIM card
slot for cellular communication. The SD card/SIM card slots are located at
the lower part of the front panel. To install them, remove the screw and
the cover to access the slots, and then insert the SD card or the SIM card.
You will hear a click when they are inserted correctly. To remove them,
push the cards in and then release them.

USB
The USB 2.0 port is located at the lower part of the front panel, and
supports a USB storage device driver.
Real-time Clock
The UC-8100’s real-time clock is powered by a non-chargeable battery.
We strongly recommend that you do not replace the battery without help
from a qualified 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 by an
incorrect type of battery.
Installing the Cellular Module
The UC-8100 provides a Mini PCIe socket for installing a cellular module.
The cellular module package includes the following items.

- 7 -
Follow these steps to install the cellular module.
1.
Unfasten the screws on the side
panel of the computer and
remove the cover.
2. Find the location of the PCIe
socket.
3. Remove the plastic plate and the
sticker on both sides of the
large thermal pad and place it
in the socket
. Press the thermal
pad down s
o that it sticks to the
base of the socket.
Place the thermal pad as close
as possible to the holes for the
screws used to secure the
module.
4. Insert the cellular module into
the socket and tighten the
screws to secure the module to
the socket.

5. Remove the plastic plate and the
sticker on both side of the
small
thermal pad and stick the
thermal pad on to the module.
6.
Install the antenna cables.
There are three antenna
connectors
on the module; two
for cellular antennas and one for
a GPS antenna. Refer to the
figure for details. As there are
only two antenna connector
holes on the front panel of the
computer, you can only use two
antennas at a time. You may use
two cellular antennas, or a
cellular antenna and a GPS
antenna. The same antenna
cables can be used for both
antenna types.
7. Connect one end of the antenna
cable to the cellular module.
8. Insert the other end of the
cable, with the connector,
through the antenna
connector
hole on the front panel of the
computer. Remove the black
plastic protection cover on the
connector hole before you insert
the antenna wire.
9. Insert the locking washer
through the connector and press
it against the cover of the
computer. Then, insert the nut
and tighten it to secure the
connector to the cover.

10. Connect the antenna to the
antenna connector.
11.
Replace the cover of the
computer.
Connecting the UC-8100 to a PC
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
CBL
-RJ45F9-150 cable included in the package to connect the
PC
to the UC-8100’s serial console port.
B. By SSH over the network. Refer to the following IP addresses and
login information.
