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 allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

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).

IMPORTANT

• 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.

• The power adapter should be connected to a socket outlet with earthing connection.
  If you need further information or assistance, contact a Moxa representative.

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.

Connecting to the Network

The Ethernet ports are located on the top or bottom panel of the UC-2100-W computers. The pin assignments for the Ethernet port are shown in the following figure. If you are using your own cable, make sure that the pin assignments on the Ethernet cable connector match the pin assignments on the Ethernet port.

Connecting to a Serial Device

The serial ports are located on the bottom panel of the UC-2100-W computer. Use a serial cable to connect your serial device to the computer’s serial port. These serial ports have male DB9 connectors and can be configured for RS-232, RS-422, or RS-485 communication. The pin location and assignments are shown in the following table.

The UC-2114 and UC-2116 computers come with one DIP switch for users to adjust the serial port parameters. To set up the DIP switch, do the following:

1. Remove the screws on the DIP switch cover located on the rear panel of the computer.
2. Remove the thin film on the DIP switch and adjust the setting as required.
   Refer to the table below for the DIP switch settings. The default value is OFF.SW| 1| 2| 3| 4
   ---|---|---|---|---
   Low| High| Term.| –
   ON| 1 KΩ| 1 KΩ| 120 Ω| –
   OFF| 150 KΩ| 150 KΩ| –| –

Real-time Clock

The real-time clock in the UC-2100-W is powered by a lithium battery. We strongly recommend that you do not replace the lithium battery without the help of a 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 with an incorrect type of battery.
