Introduction
The MOXA UC-71xx series of embedded computers (UC-7112 Plus, UC-7112, and UC-7110) are mini, RISC-based, box-type computers that feature dual 10/100 Mbps Ethernet ports, two
RS-232/422/485 serial ports, and an ARM9 processor. The computers come with Linux pre-installed. In addition, the UC-7112 Plus and UC-7112 have an internal SD socket for storage expansion to offer high performance communication with unlimited storage in a super-compact, palm-size box. The UC-71xx series of embedded computers are the right solution for embedded applications that call for a small computer, but that can store large amounts of memory and provide good computing performance.
In this chapter, we cover the following topics:

UC-7112 Plus/7112/7110 User’s Manual Introduction
Overview
The UC-71xx series of mini, RISC-based communication platforms are ideal for embedded applications. All three computers in the series (UC-7112 Plus, UC-7112, and UC-7110) come with
2 RS-232/422/485 serial ports and dual 10/100 Mbps Ethernet LAN ports to provide users with a versatile communication platform.
The UC-71xx series computers use the MOXA ART ARM9 192 MHz RISC CPU. Unlike the x86
CPU, which uses a CISC design, the ARM9’s RISC design architecture and modern semiconductor technology provide these computers with a powerful computing engine and communication functions, but without generating too much heat. The built-in NOR Flash ROM
(16 MB for UC-7112 Plus, 8 MB for UC-7112/7110) and SDRAM (32 MB for UC-7112 Plus, 16
MB for UC-7112/7110) give you plenty of storage capacity, and the SD socket provides greater flexibility for running various applications. The dual LAN ports built into the ARM9 allow the
UC-71xx computers to be used as communication platform for basic data acquisition and protocol conversion applications, and the two RS-232/422/485 serial ports allow you to connect a variety of serial devices.
The UC-7112 and UC-7110 come with the µClinux operating system pre-installed, and the
UC-7112 Plus comes with the Linux operating system with MMU support pre-installed. Software written for desktop PCs is easily ported to the UC-71xx computers with a GNU cross complier, so that you will not need to spend time modifying existing software code. The operating system, device drivers, and your own software can all be stored in the computers’ Flash memory.

UC-7112 Plus/7112/7110 Hardware User’s Manual Hardware Introduction
Internal SD Socket
The UC-7112 Plus and UC-7112 have an internal SD socket for storage expansion. A Secure
Digital (SD) memory card compliant with the SD 1.0 standard can be used to provide up to 1 GB of additional memory space. To install an SD card, first remove the outer cover of the embedded computer to access the SD slot. The internal SD slot is located on the back of the bottom board, in the slot on the right side of the UC-7112 and UC-7112 Plus, but lower than the cover screw. Plug the SD card into the socket directly and remember to “push in” the SD card first if you want to remove it.
Additional Functions
Reset Button
Press the “RESET” button continuously for more than 5 seconds to load the factory default configuration. After loading the factory defaults, the system will reboot automatically. The System
Ready LED will blink for the first 5 seconds. We recommend that you only use this function if the software is not working properly. To reset the µClinux system software, always use the software reboot command (reboot) to protect the integrity of data that is being transmitted. The reset button is NOT designed to Hard Reboot the UC-71xx series embedded computer.
ATTENTION
Restoring default settings preserves your data
Resetting the embedded computer to factory defaults will NOT cause the user directory to be reformatted, and the user’s data will NOT be deleted. The reset button only causes a configuration file to be loaded. All files in the /etc directory will revert to their factory defaults, but all other user data will remain intact in the Flash ROM.
Please note that if there is a problem with the /etc directory, the embedded computer may be unable to restore the factory default settings.
ATTENTION
This function only takes effect when the user directory is working correctly. If the user directory has crashed, the kernel will automatically load the factory defaults.
Real Time Clock
The real time clock in the UC-71xx embedded computers is powered by a lithium battery. We strongly recommend that you get help from MOXA’s technical support team to replace the lithium battery. If the battery needs to be changed, contact the MOXA RMA service team for RMA service.
ATTENTION
The battery may explode if replaced by an incorrect type. To avoid this potential danger, always be sure to use the correct type of battery.

¾ Connecting to a Serial Device
¾ Serial Console Port
UC-7112 Plus/7112/7110 Hardware User’s Manual Hardware Connection Description
Wiring Requirements
This section explains how to connect the UC-71xx embedded computers to serial devices.
You should heed the following safety precautions before installing any electronic device: y Use separate paths for power wiring and wiring for 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. y 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. y Keep input wiring and output wiring separate. y It is advisable to label the wiring to all devices in the system.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your UC-71xx embedded computer.
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.
Temperature Caution!
Be careful when handling the UC-71xx embedded computer. When plugged in, the computer’s internal components generate heat, and consequently the outer casing may feel hot to the touch.
Connecting the Power
Connect the “live-wire” end of the 12-48 VDC power adaptor to the UC-71xx’s terminal block. If the power is supplied properly, the “Ready” LED will glow a solid green color after a 25 to 30 second delay.
Grounding the UC-71xx Embedded Computer
Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Run the ground wire from the ground screw to the grounding surface prior to connecting devices.

SG: The Shielded Ground (sometimes called
Protected Ground) contact is the left most contact of the 3-pin power terminal block connector when viewed from the angle shown in the figure at the left. Connect the SG wire to an appropriate grounded metal surface.
Connecting Data Transmission Cables
This section describes how to connect the UC-71xx to the network, to serial devices, and to a serial COM terminal.
Connecting to the Network
Connect one end of the Ethernet cable to the UC-71xx’s 10/100M Ethernet port, and the other end of the cable to the Ethernet network. If the cable is properly connected, the UC-71xx will indicate a valid connection to the Ethernet in the following ways: y The top-right LED on the connector glows a solid green when connected to a 100 Mbps
Ethernet network. y The top-left LED on the connector glows a solid orange when connected to a 10 Mbps Ethernet network. y The LEDs will flash when Ethernet packets are being transmitted or received.
The 10/100 Mbps Ethernet LAN 1 and LAN 2 ports use 8-pin RJ45 connectors. Pinouts for these ports are given in the following diagram.
