Reset Button
The UC-2100-W Series computer is provided with a reset button, which
is located on the top panel of the computer. To reboot the computer,
press the reset button less than 1 second. Press and hold the reset
button between 7 to 9 seconds to reset the computer to the factory
default settings. When the reset button is held down, the User LED will
blink twice every second. The User 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
Wall or Cabinet Mounting
Use two screws per side to mount the UC-2100-W Series on a wall or
inside a cabinet.
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
This equipment is intended to be used in Restricted Access
Locations.
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your
UC-2100-W Series computers.
Wiring Caution!
Calculate the maximum possible current in each power wire
and common wire. Observe all electrical codes dictating the
maximum current allo
wable for each wire size. If the current
goes above the maximum ratings, the wiring could overheat,
causing serious damage to your equipment.

- 6 -
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.
Connecting the Power
Connect the 9 to 48 VDC power line to the
terminal block, which is connected to the UC-
2100-W 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. The input terminal block (CN5) is
suitable for a wire size of 12 to 30 AWG (3.3 to
0.05 mm2) and a torque value of 0.5 N-m
(4.425 lb-in).
I
MPORTANT
This product is intended to be supplied by a UL Listed power
adapter
or DC power source whose output meets SELV/LPS.
The power source must be
rated 9 to 48 VDC, minimum 0.6 A,
and minimum Tma = 75°C.
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. Please note that this product is intended to be
mounted on a well-grounded mounting surface, such as a metal panel.
The minimum cross-sectional area of the earthing conductor shall be
equal to the input wiring cable.
Connecting to the Console Port
The UC-2100-W console port is a 4-pin pin-header RS-232 port located
on the right panel of the case. It is designed for serial console
terminals, which are useful for viewing the boot up message, or for
debugging system boot up issues. Remove the protective cover on the
port to connect the console cable.
