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

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.

Console Port

The console port is a RS-232 port that can be connected with a 4-pin pin

header cable. You may use this port for debugging or firmware upgrade.

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.

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.

- 8 -

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.

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.

- 9 -

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

to the UC-8100’s serial console port.

B. By SSH over the network. Refer to the following IP addresses and
