and software used, etc.) Note anything abnormal and list any  
onscreen messages you get when the problem occurs.  
2.  
3.  
Call your dealer and describe the problem. Please have your man-  
ual, product, and any helpful information readily available.  
If your product is diagnosed as defective, obtain an RMA (return  
merchandize authorization) number from your dealer. This allows  
us to process your return more quickly.  
4.  
5.  
Carefully pack the defective product, a fully-completed Repair and  
Replacement Order Card and a photocopy proof of purchase date  
(such as your sales receipt) in a shippable container. A product  
returned without proof of the purchase date is not eligible for war-  
ranty service.

Chapter 1 Overview  
1.1 Introduction  
Standard PCs and some industrial computers with a standard OS and hard-  
ware for the consumer market cannot provide the reliability required by  
industrial automation and embedded industrial control applications. How-  
ever, many engineers prefer to use PCs because of their advanced func-  
tions such as: analog control and simulation, database connectivity, web-  
based applications, and communication with third-party devices. UNO-  
3074 combines the best features of a PC, including the processor, RAM,  
and powerful software, with the reliability, ruggedness, and distributed  
nature of a PLC. UNO-3074 has the compact size and ruggedness of a PLC,  
and the software flexibility and functionality of a PC. It's an ideal platform  
for sophisticated control and logging in rugged environments.  
Open Architecture Designed for Automation  
For applications demanding customized control, UNO-3074 that uses  
more flexible, off-the-shelf technology is a better option. UNO-3074 uses  
off-the-shelf components such as an x86 processor, an Ethernet chip set,  
CompactFlash and DRAM. System designers can easily create multiple  
inputs from sensors via plug-in data acquisition cards and provide outputs  
to other devices to control the operation. At the same time, the UNO-3074  
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 communication. So,  
UNO-3074 offers the I/O connectivity of PCs with options such as 2 x 10/  
100Base-T Ethernet, 2 x RS-232, 2 x RS-232/422/485, 4 x USB, Com-  
pactFlash, PC Card and PCI extension slots and VGA interfaces for dis-  
play 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 control-  
ler because their end applications are mounted in an industrial enclosure.  
Advantech UNO-3074 has a special design without the weaknesses of a  
standard PC. No fan and no HDD design prevent dust and vibration prob-  
lems. A battery-backup function secures the last state of the system, mak-  
ing system crashes less problematic. With a smart mechanical design,  
UNO-3074 can meet 50G shock, 2G vibration, up to 50° operating tem-  
perature and almost everything a harsh industrial environment demands.  
Off-the-shelf Universal PCI Extensions  
From a computing point of view, the UNO-3074 with its PC-based control  
CPU is a high-end machine controller. It can be simply operated with the  
onboard Ethernet interface or with a PC Fieldbus card. Two free PCI slots  
are also available. In addition, Advantech offers a complete product line  
for plug-in data acquisition and control I/O cards, motion control cards,  
GPIB cards, industrial communication and Fieldbus communication cards,  
providing a complete PC-based solution.  
Front Access Connections  
All PC connections are on one side of the housing. The PC can optionally  
be equipped with mounting plates and fastened with screws in a control  
cabinet. All mechanical parts have a simple design, and the drivers and  
plug-in cards are easily accessible without compromising system perfor-  
mance or integrity. The installation options are also well balanced.  
Designed to Fit Into Control Cabinets  
The fully-fledged UNO-3074 could easily be mistaken for a PLC by its  
look and feel. In completely new packaging, the smallest UNO only mea-  
sures 180 x 177 x 237 mm (W x H x D). But the UNO-3074 not only deals  
with PLC tasks, but also offers all the operating and communication power  
of a modern PC with its Intel Celeron or Pentium III processor and Win-  
dows Operating System software. So, Adventech UNO-3074 is a small,  
powerful and inexpensive PLC substitute.

Onboard DI/O for Counter, Alarm/Event Handling  
UNO-3074 features onboard DI and DO. These DIs and DOs can be used  
as 32-bit counters or to handle alarms and events. Any events can be  
passed to UNO-3074 through DIs with an additional DI plug-in card.  
UNO-3074 can also output alarms through onboard DOs immediately to  
notify key personnel about urgent events.  
Flexible Networking Options  
UNO-3074 offers three ways to connect to a network: Ethernet, Wireless  
LAN and Modem. The two built-in Ethernet ports provide high-speed net-  
working capability up to 100 Mbps. The PCMCIA extension with PCM-  
CIA wireless LAN module offers you a mobile and scalable network  
without incurring additional cabling costs. And through COM ports of  
UNO-3074, industrial modems offer the most popular and easiest net-  
working method by PSTN.  
Popular Operating Systems and Rapid Application Development  
UNO-3074 supports the popular off-the-shelf Microsoft Windows 2000/  
NT/XP operating systems and the Linux operating system. UNO-3074 also  
features pre-built Microsoft Windows XP embedded or Windows CE solu-  
tions offering a pre-configured image with optimized onboard device driv-  
ers. 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-3000 series. Through the built-in runtime library and Software  
Development Kit (SDK), the UNO-3000 series leverages your existing  
Windows-based programming skills to rapidly develop applications.

cases, you will simply need to connect a standard cable.  
Note:  
Note:  
Note:  
Always disconnect the power cord from your chas-  
sis whenever you are working on it. Do not connect  
while the power is on. A sudden rush of power can  
damage sensitive electronic components. Only  
experienced electronics personnel should open the  
chassis.  
Always ground yourself to remove any static elec-  
tric charge before touching UNO-3074. Modern  
electronic devices are very sensitive to static elec-  
tric charges. Use a grounding wrist strap at all  
times. Place all electronic components on a static-  
dissipative surface or in a static-shielded bag.  
If DC voltage is supplied by an external circuit,  
please put a protection device in the power supply  
input port.

2.2 RS-232 Interface (COM1~COM2)  
The UNO-3074 offers two industrial standard RS-232 serial communica-  
tion interface ports: COM1 and COM2. Please refer to Appendix A.4 for  
their pin assignments.  
The IRQ and I/O address range of COM1 and COM2 are listed below:  
COM1: 3F8H, IRQ4  
COM2: 2F8H, IRQ3  
2.3 RS-232/422/485 Interface (COM3~COM4)  
The UNO-3074 offers two industrial RS-232/422/485 serial communica-  
tion interface ports: COM3 and COM4. Please refer to Appendix A.5 for  
their pin assignments. The default setting of COM3 and COM4 are RS-  
422/485. (Please refer to section 2.3.4 for how to determine RS-232 or  
RS-422/485)  
2.3.1 16C550 UARTs with 16-byte FIFO Standard  
Advantech UNO-3074 comes with 16C550 UARTs containing 16 bytes  
FIFOs.  
2.3.2 RS-422/485 Detection  
In RS-422/485 mode, UNO-3074 automatically detects signals to match  
RS-422 or RS-485 networks. (Refer to section 2.3.5)  
2.3.3 Automatic Data Flow Control Function for RS-485  
In RS-485 mode, UNO-3074 automatically detects the direction of incom-  
ing data and switches its transmission direction accordingly. So no hand-  
shaking signal (e.g. RTS signal) is necessary. This lets you easily build an  
RS-485 network with Data+, Data- and Ground. More importantly, appli-  
cation software previously written for full-duplex RS-232 environments  
can be maintained without modification.

2.3.4 RS-232/422/485 Selection  
COM3 and COM4 support 9-wire 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 COM3, adjust JP4. To  
select between RS-422/485 and RS-232 for COM4, adjust JP5.  
You can refer to figures below to set the JP4 and JP5.

2.3.5 RS-485 Auto Flow/RS-422 Master/Slave Selection  
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.  
(Refer to Figure A.3 for location of SW2).  
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.  
Then 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.

2.5.2 Isolated Inputs  
Each of isolated digital input channels accepts 0 ~ 50 VDC voltage inputs,  
and accepts bi-directional input. The voltage range is -3 ~ 3 VDC for logic  
0 (low), -50 ~ -10 VDC and 10 ~ 50 VDC for logic 1 (high). It means that  
you can apply positive or negative voltage to an isolated input pin (Vin).  
All channels share one common pin (COM). Figure 2.5 shows how to con-  
nect an external input source to one of the UNO-3074 isolated input chan-  
nels.  
Please note that DI0 and DI2 may be configured as gate control pins of  
Counter 0 and Counter 1; While DI1 and DI3 may be configured as input  
pins of Counter 0 and Counter 1. Please refer to section 2.7 for  
details

2.5.3 Interrupt Function of the DI Signals  
DI0 and DI1 can be used to generate hardware interrupts. Users can setup  
the configuration of them by programming the interrupt control register.  
The channels are connected to the interrupt circuitry. Users can disable/  
enable interrupt function, select trigger type or latch the port data by set-  
ting the Interrupt Control Register of the UNO-3074 (refer to section 2.5.5  
below). When the interrupt request signals occur, then the software will  
service these interrupt requests by ISR (Interrupt Service Routine). The  
multiple interrupt sources provide the card with more capability and flexi-  
bility.  
2.5.4 IRQ Level  
The IRQ level is by default set by the system BIOS. IRQ 7 is reserved for  
DI interrupt and counter interrupt.

2.6.2 Power On Configuration  
Default configuration after power on or hardware reset is to set all the iso-  
lated digital output channels to open status (the current of the load can’t be  
sink) so that users need not worry about damaging external devices during  
system startup or reset. When the system is hot reset, then the status of iso-  
lated digital output channels are selected by jumper JP7. Table 2.10 shows  
the configuration of jumper JP7.  
Note: Please refer to Figure A.3 for location of JP7  
Table 2.10: Digital Output Power On Configuration  
Power on configuration after hot reset  
JP7  
Reset all digital output  
(default configuration)  
Keep last status after hot reset  
2.6.3 Isolated Outputs  
Each of isolated output channels comes equipped with a Darlington tran-  
sistor. All output channels share common emitters.  
Please note that if an external voltage (5 ~ 40 VDC) is applied to an iso-  
lated output channel while it is being used as an output channel, the cur-  
rent will flow from the external voltage source to the UNO-3074. Please  
take care that the current through each DO pin not exceed 200 mA. Figure  
2.7 below shows how to connect an external output load to the UNO-3074  
isolated outputs.  
Please note that DO2 and DO3 may be configured as output pins of  
Counter 0 and Counter 1 (please refer to section 2.7 for more details)

2.7 Onboard Isolated Counter/Timer  
The UNO-3074 uses one 82C54 programmable timer/counter chip that  
includes three independent 16-bit down counters: counter 0, counter 1 and  
counter 2. Counter 0 and counter 1 are for users, and counter 2 is specified  
for the system and can’t be used by user. Each counter has clock input, gate  
input and pulse output. They can be programmed to count from 2 up to  
65535 or cascaded into one 32-bit counter.  
The UNO-3074 has two isolated counter input channels designated DI1  
and DI3 with two isolated output channels designated DO2 and DO3.  
Therefore, you can set each counter of 82C54 as counter function or timer  
function.  
2.7.1 Counter/Timer Control Register  
The Counter/Timer Control Register controls the function and status of  
each counter/timer signal source. Table 2.11 shows the bit map of the  
Counter/Timer Control Register. The register is readable/writable register.  
While being written, it is used as a control register; and while being read,  
it is used as a status register.

2.8 Power Input  
UNO-3074 comes with a Phoenix connector that carries 16~36 VDC exter-  
nal power input, and features reversed wiring protection. Therefore, it will  
not cause any damage to the system by reversed wiring of ground line and  
power line. (Please refer to Figure 2.11 for location of power input)  
The UNO-3074 supports two individual power inputs (P1/P2).  
refer to Appendix A.7 for wiring of P1 and P2)

You can see the LED indicators to monitor power input situation. (Please  
refer to Figure 2.12 for location of LED). If the voltage of power input  
P1> 15 VDC, the P1 LED indicator will be enable (means the first power  
input is used). It is the same for P2 LED indicator (to show if the voltage  
of power input P2 > 15 VDC). When any voltage of P1 and P2 < 15VDC,  
the Fault LED will be enable. It means that you don’t use redundancy  
power input. When you have two power inputs, the system will use the  
power inputs with higher voltage.  
Note: UNO-3074 provides built-in examples to show how to  
monitor power input status. Refer to console mode  
examples in  
C:\Program Files\Advan-  
tech\UNO\UNO_IsaDIO\Examples\Console.

2.9 LED and Buzzer for System Diagnosis  
In a “headless application” (an application without a monitor display), it is  
always difficult to know the system status. Another PC may be needed to  
monitor a headless device's status via RS-232 or Ethernet. In order to  
solve this problem, UNO-3074 offers a programmable LED indicator (Fig-  
ure 2.13) and buzzer. They can be programmed to show a systems status by  
LED indicator flickering and buzzer alarm.

PS/2 Keyboard and Mouse Connector  
The UNO-3074 provides a PS/2 keyboard and PS/2 mouse connector. A 6-  
pin mini-DIN connector is located on the front panel of the UNO-3074.  
UNO-3074 comes with an adapter in the accessory package (see section  
1.5) to convert from the 6-pin mini-DIN connector to two 6-pin mini-DIN  
connectors for PS/2 keyboard and PS/2 mouse connection. Please refer to  
Appendix A.8 for its pin assignments.  
2.10 USB Connector  
The USB connector is used for connecting any device that conforms to the  
USB interface. Many recent digital devices conform to this standard. The  
USB interface supports Plug and Play, which enables you to connect or  
disconnect a device whenever you want, without turning off the computer.  
The UNO-3074 provides four connectors of USB interfaces. The USB  
interface complies with USB UHCI, Rev. 2.0 compliant. The USB inter-  
face can be disabled in the system BIOS setup. Please refer to Appendix  
A.9 for its pin assignments.  
2.11 PCMCIA: PC Card Slot  
The UNO-3074 provides one PC Card slot that supports CardBus (Card-  
32) cards and 16-bit (PCMCIA 2.1/JEIDA 4.2) card standards. It supports  
+3.3 V, +5 V and +12 V @ 120 mA working voltage. The PC Card is 85.6  
mm long by 54 mm wide (3.37" x 2.126"), using a 68-pin connector and a  
removable module standardized by PCMCIA that is known as “PCMCIA  
card”  
Note: PCMCIA interrupt assignment is IRQ 9. If you use  
Win2000 OS you need to check the IRQ manually.

Note: Please don’t change the IRQ of PCMCIA adapters. This  
is PCMCIA controller. (As shown by figure below) We  
need to configure the IRQ of the PCMCIA device,  
instead of PCMCIA controller.  
For example, if you insert one PCMCIA IDE card, this card will appear in the  
IDE ATA/ATAPI controllers (as the figure below). So please pay attention  
that the PCMCIA will appear in the difference place of device manager  
according to the type of PCMCIA. Please double click on the PCMCIA  
device.

2.12 VGA Display Connector  
The UNO-3074 provides a VGA controller (Intel 852/855GME GMCH/  
ICH4 Chipset 400 MHz PSB) for a high resolution VGA interface. It sup-  
ports CRT mode: 1280 x 1024 @ 32bpp (60Hz), 1024 x 768 @ 32bpp  
(85Hz) and supports 8/16/32 MB frame buffer with system memory.  
Note:  
UNO-3074 also support 16:9 flat screen.  
Note: UNO-307x VGA chipsets is similar with commercial lap-  
top VGA chipsets. Sometimes if there is no image on  
the monitor, it might be that VGA signal doesn’t output to  
the monitor, just like when we connect a monitor to lap-  
top VGA connector, we need to manually switch the  
VGA output from laptop screen to external monitor. So  
you could use hot key “CTRL+ALT+F1” to output the  
VGA signal to monitor.  
You can set the hot-key and other configuration for the VGA Graphics  
(Please refer to the two images below)

Figure 3.8: UNO-3074 Correct Installation  
Note: Because the heat transfer mechanism is designed  
close to the right side of system, make sure not to  
attach the right side of the UNO chassis to the wall or  
ground (shown in Figure 3.10 and 3.11). It may cause  
the system to hang. Instead, try to allow some space  
on the right side of UNO chassis. (Figure 3.12).  
Note: The UNO-3000 series is fanless and depends on the  
heat sink to transfer heat. The procedure for installing  
the heat-sink on the mainboard is complex, so don’t try  
to move the mainboard from the chassis and backplane.  
(If you uninstall the mainboard and cannot install it cor-  
rectly back to chassis, the system may not be able  
transfer heat and will crash)
