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 theslot just below the stiff metal spring inthe upper hook of the DIN-rail mounting kit. MOXA UC-5100 Series Arm

2 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 electrical 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 intended 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.
This 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.
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.
