Introduction

The UC-3100 Series computing platform is designed for embedded data acquisition applications. The computer comes with two RS- 232/422/485 serial ports and dual auto-sensing 10/100 Mbps Ethernet LAN ports. These versatile communication capabilities let users efficiently adapt the UC-3100 to a variety of complex communications solutions. The following topics are covered in this chapter: Overview Model Description Package Checklist Product Features Hardware Specifications

Overview

Moxa UC-3100 Series computers can be used as edge-field smart gateways for data pre-processing and transmission, as well as for other embedded data acquisition applications. The UC-3100 Series includes three models, each supporting different wireless options and protocols.
The UC-3100’s advanced heat dissipation design makes it suitable for use in temperatures ranging from -30 to 70°C. In fact, the Wi-Fi and LTE connections can be used simultaneously in both cold and hot environments, allowing you to maximize your “data pre-processing” and “data transmission” capability in most harsh environments.

Reset to Factory Default

For details on resetting your device to factory default values, refer to the Function Button and LED Indicators section.
ATTENTION
Reset to Default will erase all the data stored on the boot storage
Please back up your files before resetting the system to the factory default configuration. All the data stored in the UC-3100`s boot storage will be erased when it is reset to the factory default configuration.
Real-time Clock
The real-time clock in the UC-3100 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.
WARNING
There is a risk of explosion if the battery is replaced with an incorrect battery type.

Placement Options

The UC-3100 computer can be mounted on to a DIN rail or on a wall. The DIN- rail mounting kit is attached by default. To order a wall-mounting kit, contact a Moxa sales representative.
DIN-rail Mounting
To mount the UC-3100 onto a DIN rail, do the following:

1. Pull down the slider of the DIN-rail bracket located at the back of unit
2. Insert the top of the DIN rail into the slot just below the upper hook of the DIN-rail bracket.
3. Latch the unit firmly onto the DIN rail as shown in the illustrations below.
4. Once the computer is mounted properly, you will hear a click and the slider will rebound back into place automatically.

Wall Mounting (optional)
The UC-3100 can also be wall-mounted. The wall-mounting kit needs to be purchased separately. Refer to the datasheet for more information.

1. Fasten the wall-mounting kit to the UC-3100 as shown below:
2. Use two screws to mount the UC-3100 onto a wall.

ATTENTION
The wall-mounting kit is not included in the package and must be purchased separately.

Hardware Connection Description

This section describes how to connect the UC-3100 to a network and connect various devices to the UC3100. The following topics are covered in this chapter:
Wiring Requirements
Connector Description
In this section, we describe how to connect various devices to the embedded computer. You must pay attention to the following 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 the wires for signal or communication and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.
• You can 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. · We strongly advise that you label wiring to all devices in the system for easy identification.

**** ATTENTION

Safety First!
Be sure to disconnect the power cord before installing and/or wiring the computer.
Electrical Current 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.
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 be hot to touch by hand.

Connector Description

Power Connector
Connect the power jack (in the package) to the UC-3100’s DC terminal block (located on the bottom panel), and then connect the power adapter. It takes several seconds for the system to boot up. Once the system is ready, the SYS LED will light up.
Grounding the UC-3100
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). There are two ways to connect the UC-3100 grounding wire to the ground.

1. Through the SG (Shielded Ground, sometimes called Protected Ground): The SG contact is the left-most contact in the 3-pin power terminal block connector when viewed from the angle shown here. When you connect to the SG contact, the noise will be routed through the PCB and the PCB copper pillar to the metal chassis.

2. Through the GS (Grounding Screw): The GS is located between the console port and the power connector. When you connect to the GS wire, the noise is routed directly from the metal chassis.

Ethernet Port
The 10/100 Mbps Ethernet port uses the RJ45 connector. The pin assignment of the port is shown below:

Serial Port
The serial port uses the DB9 male connector. It can be configured by software for the RS-232, RS-422, or RS-485 mode. The pin assignment of the port is shown below:

­CAN Port (UC-3121 only)
The UC-3121 comes with a CAN port that uses the DB9 male connector and is compatible with the CAN 2.0A/B standard. The pin assignment of the port is shown below:

SIM Card Socket

­The UC-3100 comes with two nano-SIM card sockets for cellular communication. The nano-SIM card sockets are located on the same side as the antenna panel. To install the cards, remove the screw and the protection cover to access the sockets, and then insert the nano-SIM cards into the sockets directly. You will hear a click when the cards are in place. The left socket is for SIM 1 and the right socket is for SIM 2. To remove the cards, push the cards in before releasing them.

­RF Connectors
The UC-3100 comes with RF connectors to the following interfaces.
Wi-Fi
The UC-3100 comes with a built-in Wi-Fi module (UC-3111 and UC-3121 only). You must connect the antenna to the RP-SMA connector before you can use the Wi-Fi function. The W1 and W2 connectors are interfaces to the Wi-Fi module.
Bluetooth
The UC-3100 comes with a built-in Bluetooth module (UC-3111 and UC-3121 only). You must connect the antenna to the RP-SMA connector before you can use the Bluetooth function. The W1 connector is the interface to the Bluetooth module.
Cellular
The UC-3100 comes with a built-in cellular module. You must connect the antenna to the SMA connector before you can use the cellular function. The C1 and C2 connectors are interfaces to the cellular module. For additional details refer to the UC-3100 datasheet.
SD Card Socket (UC-3111 and UC-3121 US only)
The UC-3111 comes with an SD-card socket for storage expansion. The SD card socket is located next to the Ethernet port. To install the SD card, remove the screw and the protection cover to access the socket, and then insert the SD card into the socket. You will hear a click when the card is in place. To remove the card, push the card in before releasing it.
Console Port
The console port is an RS-232 port that you can connect to with a 4-pin pin header cable (in the package). You can use this port for debugging or firmware upgrades.

USB
The USB port is a type-A USB 2.0 version port, which can be connected with a USB storage device or other type-A USB-compatible devices.
