Chapter 1 Overview
1.1 Introduction
UNO-4678 is an embedded Application Ready Platform (ARP) that can
shorten your development time and offers rich networking interfaces to
fulfill extensive needs in different projects. Advantech Universal Net-
work Controller is designed to be a total solution for network enabled
Application Ready Platforms.
Leveraging field-approved and worldwide approved real-time OS tech-
nology, Advantech UNO-4678 series provides a Windows CE .NET and
Windows XP Embedded ready solution, and supports several standard
networking interfaces, such as Ethernet, RS-232/422/485 and more.
Because of its openness, great expansion capability and reliable design
(fanless and diskless), the UNO-4678 series are ideal embedded plat-
forms for implementing custom applications for diverse applications.
Open Architecture Designed for Automation
For applications demanding customized control, an UNO-4678 that uses
more flexible, off-the-shelf technology is a better option. UNO-4678 uses
off-the-shelf components such as an x86 processor, an Ethernet chip set,
CompactFlash., and DRAM. At the same time, the UNO-4678 unit can
broadcast the process data through the Ethernet and share the data with
operators and managers. By using off-the-shelf components, machine
builders can customize the control scheme they use for other machines
that require multiple inputs, optimized control, or Ethernet communica-
tion. So, UNO-4678 offers the I/O connectivity of PCs with options like:
3 x 10/100Base-T Ethernet, 8 x RS-232/422/485, 2 x USB, CompactFlash
and VGA interfaces for display panels.
An Industry-Proven Design
Industrial and mobile applications require controllers with high-vibration
specifications and a wide temperature range. Machines or controllers in
light industrial environments also require flexible and stable mounting.
Many machine builders underestimate the need for a more rugged con-
troller because their end applications are mounted in an industrial enclo-
sure.

3 Chapter1
Advantech UNO-4678 has a special design without the weaknesses of a
standard PC. No fan, and no HDD prevent dust and vibration problems.
With a smart mechanical design, UNO-4678 can meet 50 G shock (Use
CompactFlash card ), 2 G vibration (Use CompactFlash card ), up to 50°
C operating temperature and almost anything an industrial environment
can demand.
Designed to Fit Comfortably Into Racks
In completely new packaging, UNO-4678 has standard 1U rack size as
440 x 220 x 44 mm (W x H x D) could fit your rack. You could easily
mount UNO-4678 on rack and manage all UNOs in one rack and easily
develop your application on rack.
Flexible Networking Options
The Advantech UNO-4678 offers two ways to connect to a network:
Ethernet and Modem. The three built-in Ethernet ports provide high-
speed networking capability up to 100 Mbps. And through UNO-4678’s
isolated serial COM ports, you could link industrial modems to offer the
most popular and easiest networking method by PSTN. Not only 8 chan-
nel serial COM port has 3 serial type but also provides surge and isolation
protection up to 2,000VDC, protecting your system from abrupt high volt-
age attack and accident or damage in harsh environments.
Popular Operating Systems and Rapid Application Development
The Advantech UNO-4678 supports the popular off-the-shelf Microsoft
Windows 2000/NT/XP operating systems and the Linux operating sys-
tem. UNO-4678 also features pre-built Microsoft Windows XP embedded
or Windows CE solutions offering a pre-configured image with optimized
onboard device drivers. Microsoft Windows CE and XP Embedded are
compact, highly efficient, and real-time operating systems that are
designed for embedded systems without a HDD. There is no need to
waste time and energy on developing onboard device drivers or using the
Platform Builder to build a custom Windows CE image, they have all
been done for the Advantech UNO-4678 series! Through the built-in
runtime library and Software Development Kit (SDK), the UNO-4678
series leverages your existing Windows-based programming skills to rap-
idly develop applications.

1.3 Safety Precautions
The following,messages informs how to make each connection. In most
cases, you will simply need to connect a standard cable.
Warning! Always disconnect the power cord from your
chassis whenever you are working on it. Do not
connect while the power is on. A sudden rush of
power can damage sensitive electronic compo-
nents. Only experienced electronics personnel
should open the chassis.
Caution! Always ground yourself to remove any static
electric charge before touching UNO-4678. Mod-
ern electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag.
Attention! If DC voltage is supplied by an external circuit,
please put a protection device in the power sup-
ply input port.

2.2 RS-232/422/485 Interface (COM1~COM8)
The UNO-4678 offers eight RS-232/422/485 serial communication inter-
face ports: COM1 and COM8. Please refer to Appendix A.3 & A.4 for
their pin assignments. The default settings of COM1 through COM8 are
all RS-232.
2.2.1 16PCI954 UARTs with 128-byte standard
Advantech UNO-4678 comes with 16PCI954 UARTs containing 128
byte FIFOs.
2.2.2 RS-422/485 detection
In RS-422/485 mode, UNO-4678 automatically detects signals to match
RS-422 or RS-485 networks. (No jumper change required)
2.2.3 Automatic Data Flow Control Function for RS-485
In RS-485 mode, UNO-4678 automatically detects the direction of
incoming data and switches its transmission direction accordingly. So no
handshaking signal (e.g. RTS signal) is necessary. This lets you conve-
niently build an RS-485 network with just two wires. More importantly,
application software previously written for half duplex RS-232 environ-
ments can be maintained without modification.

UNO-4678 User Manual 12
2.2.4 RS-232/422/485 Selection
COM1 ~ COM8 support RS-232, RS-422 and RS-485 interfaces. The
system detects RS-422 or RS-485 signals automatically in RS-422/485
mode.
To select between RS-422/485 and RS-232 for COM1 ~ COM8, adjust
JP3 ~ JP10.
Jumper settings for RS-422/485 interface: (JP3 ~ JP10)
Figure 2.3: RS-422/485 jumper setting
Jumper settings for RS-232 interface: (Default setting) (JP3 ~ JP10)
Figure 2.4: RS-232 jumper setting
2.2.5 Auto Flow Control & Master/Slave Modes
You can set the “Auto Flow Control” mode of RS-485 or “Master/Slave”
mode of RS-422 by using the SW2 DIP switch for each RS-422/485 port.
In RS-485, if the switch is set to “Auto”, the driver automatically senses
the direction of the data flow and switches the direction of transmission.
No handshaking is necessary.
In RS-422, if DIP switch is set to “On,” the driver is always enabled, and
always in high or low status.
2.2.6 Termination Resistor (JP1 ~ JP8)
The onboard termination resistor (120 ohm) for COM1 ~ COM8 (J1 ~ J8)
can be used for long distance transmission or device matching. (Default
Open.).
