Reset Button
The UC-5100 computer is provided with a Reset button, which is
located on the front panel of the computer. To reboot the computer,
press the reset button for 1 second.
Reset to Default Button
The UC-5100 is also provided with a Reset to Default button which
can be used to reset the operating system back to the factory default
status. Press and hold the Reset to Default button between 7 to 9
seconds to reset the computer to the factory default settings. When the
reset button is held down, the Ready LED will blink once every second.
The Ready LED will become steady when you hold the button
continuously for 7 to 9 seconds. Release the button within this period to
load the factory default settings.
Installing the Computer
DIN-Rail Mounting
The aluminum DIN-rail attachment plate comes attached to the product
casing. To mount the UC-5100 on to a DIN rail, make sure that the stiff
metal spring is facing upwards and follow these steps.
Step 1
Insert the top of the DIN rail
into the slot just below the stiff
metal spring in the upper hook
of the DIN-rail mounting kit.
Step 2
Push the UC-5100 towards the
DIN rail until the DIN-rail
attachment bracket snaps into
place.

Wiring Requirements
Be sure to read and follow these common safety precautions before
proceeding with the installation of any electronic device:
•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.
•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.
•It is strongly advised that you label wiring to all devices for easy
identification.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your
UC-5100 Series computers.
Wiring Caution!
Calculate the maximum possible current in each power wire and
common wire. Observe all electri
cal 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.
This equipment is
inten
ded to be supplied by a certified External Power Supply,
the
output of which meets SELV and LPS regulations.
Temperature Caution!
Be careful when handling the unit. When the unit is plugged in,
the internal components generate heat, and consequently the
outer casing may feel hot to the touch.
Th
is equipment is intended for installation in Restricted Access
Locations.
Connecting the Power
Connect the 9 to 48 VDC power line to the
terminal block
, which is connector to the UC-
5100
Series computer. If the power is supplied
properly, the
Power LED will glow a solid green
light
. The power input location and pin definition
are shown in the
adjacent diagram.
SG:
The Shielded Ground (sometimes called
Protected Ground) contact is
the contact at the
bottom
of the 3-pin power terminal block
connector when viewed from the angle shown
here. Connect the wire to an appropriate
grounded metal surface
or to the grounding
screw on top of the device.

- 7 -
NOTE
The input rating of UC-5100 Series is 9-48 VDC, 0.95-0.23 A.
Grounding the Unit
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from
the terminal block connector to the grounding surface prior to
connecting the power. Note that this product is intended to be mounted
on a well-grounded mounting surface, such as a metal panel.
Connecting to the Console Port
The UC-5100’s console port is an RJ45-based RS-232 port located on
the front panel. It is designed for connecting to serial console terminals,
which are useful for viewing boot up messages, or for debugging
system boot up issues.

Connecting to a Serial Device
The serial ports are located on the front panel of the UC-5100
computer. Use a serial cable to connect your serial device to the
computer’s serial port. These serial ports have RJ45 connectors and can
be configured for RS-232, RS-422, or RS-485 communication. The pin
location and assignments are shown in the table below.

Connecting the Cellular/Wi-Fi Module and
Antenna
The UC-5102 and UC-5112
computers come with one
Mini PCIe socket for
installing a cellular or Wi-Fi
module. Unfasten the two
screws on the right panel to
remove the cover and find
the location of the socket.
The cellular module package includes 1 cellular module, and 2 screws.
The cellular antennas should be purchased separately to fit your
installation requirements.
Follow these steps to install the cellular module.
1. Set the antenna cables aside
for convenience of installation
and clear the wireless module
socket as shown in the figure.

2. Insert the cellular module
into the socket and fasten
two screws (included in the
package) on to the top of the
module.
We recommended using a
tweezer when installing or
removing the module.
3. Connect the free ends of the
two antenna cables next to
the screws as shown in the
image.
4. Replace the cover and secure
it using two screws.
5. Connect the cellular antennas
to the connectors.
Antenna connectors are
located on the front panel of
the computer.
The Wi-Fi module package includes 1 Wi-Fi module, and 2 screws. The
antenna adapters and Wi-Fi antennas should be purchased separately
to fit your installation requirements.
Follow these steps to install a Wi-Fi module.
1. Set the antenna cables
aside for convenience of
installation and clear the
wireless module socket as
