This chapter provides informa­tion on the hardware setup proce­dures, including instructions for
connecting jumpers, peripherals,
switches, and indicators, as well
as mechanical drawings. Please
read all safety precautions before
beginning installation.

2.1 Jumpers

2.1.1 Jumper Description

Cards can be configured by setting jumpers. A jumper is a metal bridge used to close
an electric circuit. It consists of two metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to connect them. To close a jumper, con­nect the pins with the clip. To open a jumper, simply remove the clip. Some jumpers
have three pins, labeled 1, 2 and 3. In this case, connect either pins 1 and 2, or 2 and

3.

The jumper settings are schematically depicted in this manual as follows:

A pair of needle-nose pliers may be required to adjust the jumpers. For advice
regarding the optimum hardware configuration for your needs, contact your local dis­tributor or sales representative before making any changes.

Generally, a standard cable can support most connections.

Warning! To avoid damaging the computer, always turn the power supply off

before setting jumpers.

2.3.2.3 Another Thermal Solution - Heat Spreader

MIO-2270 can accommodate an optional heat spreader for a more comprehensive
compact system. Conducting heat to the chassis using a heat spreader is extremely
beneficial when systems are extra compact or have limited space for heat convec­tion. Guidelines for heat spreaders are provided below:

1. For optimal heat conduction, minimize the gap between the chassis and heat

spreader; the smaller the gap, the better.

2. The default heat spreader height is 11.2 mm (Advantech P/N:

1960065075N001). However, if a different height is required to better fit the
chassis, Advantech can customize the heat spreader according to your needs.
Please contact our sales center for further information.

3. The heat spreader kit contains thermal grease and screws. If the chassis is

positioned near the heat spreader, thermal grease can be applied to enhance
conduction. Alternatively, if the chassis is positioned far from the heat spreader,
a thermal pad should be employed. A gap of less than 3 mm is recommended
for superior heat conduction.

Installation

4.1 S/W Introduction

The purpose of Advantech’s embedded software services is to enhance the ease of
using Advantech platforms and Microsoft® Windows® embedded technology. Advan­tech platforms are designed to support Windows embedded software products to
effectively accomodate all the needs of the embedded computing community. For
customers, the eliminates the hassle customers of dealing with multiple vendors
(hardware suppliers, system integrators, and/or embedded OS distributors). Our goal
is to ensure that Windows embedded software solutions are widely available to the
embedded computing community.

4.2 Driver Installation

4.2.1 Windows 7 Professional

To install the necessary drivers, insert the driver CD into the DVD-ROM, select the
drivers for installation, then launch the setup file in each function folder. Follow the
Driver Setup instructions to complete all installations.

4.2.2 Alternate OS

To install drivers for another Windows OS or Linux, locate the appropriate setup file
for the speific OS.

4.3 Value-Added Software Services

Software APIs can be used to define how an application program requests services
from libraries and/or an OS. These interfaces not only specify the required drivers,
but also provide numerous user-friendly, intelligent, and integrated interfaces,
thereby speeding up development, enhancing security, and offering add-on value to
Advantech platforms.

4.3.1 SUSI Introduction

To provide programmers with easy and convenient access to hardware, Advantech
developed an API suite in the form of a program library. This program library is known
as the Secured and Unified Smart Interface, and is referred to as SUSI.

With contemporary OS, user applications cannot access the hardware directly,
necessitating the use of drivers. User applications can only access the hardware
through drivers. Because the driver interface typically varies for different OS, user
application requests for hardware access differ between various OS. However, an
abstraction layer can be built on top of the drivers to provide a uniform interface for
accessing hardware. SUSI is an example of this type of abstraction layer. SUSI pro­vides a uniform API for application programmers to access hardware functions using
different OS and Advantech hardware platforms.

Application programmers can initiate the functions supported by SUSI rather than
requesting the drivers directly. The benefit of using SUSI is portability. Specifically,
the same APIs can be defined for different Advantech hardware platforms and imple­mented on different OS. This user manual describes several sample programs as
well as SUSI and the APIs. The hardware functions supported by SUSI, such as
watchdog timer, SMBus, GPIO, and VGA control, can be grouped into categories.
The APIs for each category are briefly described in the following section.

MIO-2270 User Manual 42

4.3.2 Software APIs

4.3.2.1 GPIO API

The General Purpose Input/Output (GPIO) API is a flexible parallel interface that
enables various custom connections and allows users to monitor the signal input
level or set the output status to switch on/off a device. This API also facilitates pro­grammable GPIO, which allows developers to dynamically set the GPIO input or out­put status.

4.3.2.2 SMBus API

The System Management Bus (SMBus) API is a two-wire interface established by
Intel Corporation in 1995, based on the same operation principles of I

personal computers and servers for low-speed system management communica­tions. At present, SMBus is incorporated in many types of embedded systems. Simi­lar to other SUSI APIs, the SMBus API is available on numerous platforms including
Windows 7.

4.3.2.3 Display Control API

Two VGA control APIs exist; one for backlight on/off control, and one for brightness
control. These APIs allow developers to turn the backlight on or off and to control the
brightness.

1. Brightness Control
– The Brightness Control API allows developers to interface with an embedded

device and adjust the display brightness.

2. Backlight Control
– The Backlight API allows developers to control the backlight (screen) of an

embedded device.

C, and used in

Chapter 4 S/W Introduction and Installation

4.3.2.4 Watchdog API

A watchdog timer (WDT) is a hardware device that triggers a specific action, e.g.,
system reboot, if the system does not reset the timer within a specified period of time.
The WDT API in SUSI enables developers to start the timer, reset the timer, and set
the timeout value for hardware that requires customized timeout values.

4.3.2.5 Hardware Monitor API

The hardware monitor (HWM) enables system health supervision using I/O chips
combined with sensors to monitor certain condition indices, such as fan speed, tem­perature, voltage, etc.

However, because of the inaccuracy of many commercial hardware monitoring chips,
Advantech developed a unique scheme for hardware monitoring; that is, using a ded­icated microprocessor and specifically designed algorithms to provide accurate and
reliable real-time data to ensure system protection.

4.3.2.6 Power Saving API

1. CPU Speed
– The Power Saving API uses Intel SpeedStep® technology to reduce the sys-

tem power consumption. The CPU speed is automatically adjusted according
to the system load.

2. System Throttling
– System throttling refers to various methods for reducing power consumption

by lowering the clock frequency. The Power Saving API allows users to
reduce the clock frequency from 87.5% to 12.5%.

SusiDemo.exe is an executable file that equips the shared library, Susi.dll, with SUSI
functionalities. The SusiDemo.exe source code should be compiled using Microsoft
Visual C++ 6.0 in Windows 7. Developers must add the header (Susi.h) and library
(Susi.lib) files to their project folders before using SUSI to develop programs.

SusiDemo.exe

The SusiDemo.exe test application uses all functions of the SUSI Library and fea­tures five main function blocks: Watchdog, GPIO, SMBus, and VGA control. The pop­up menu shown in the screenshot below appears SusiDemo.exe is executed. To
select different test functions, click on the function tabs. Some function tabs may not
be available for the test application if your platform does not support such functions.
The steps for testing all functions of this application are described below.

neously. Select the pin bank number from the Bank number menu to set and
obtain the values for an entire bank pins.

 Supported Inputs/Outputs for GPIO Pins

– The supported inputs and outputs data indicate whether each pin is available

or controllable as an input or output. A value of 1 indicates that the specified
transmission direction is supported. In the example screenshot provided
above, the board only supports eight GPIO pins in Bank 0.

 Mask for GPIO Pins

– Masks are used to define which pins are enabled (Bit 1) or disabled (Bit 0) for

setting or obtaining the direction and level.

– Before setting the direction and level of GPIO pins, mask values should be

specified. Zero cannot be set as the value for all masks.

 Direction Setting

– The Direction value specifies the I/O direction of each pin; 1 denotes input

and 0 denotes output.

 SMBus Device Slave Address

– Input the slave address of a specific SMBus device in the Slave Address data

field. Please refer to the “Probe for SMBus Device” subsection for instruc­tions on how to obtain existing device addresses.

– The Slave Address must be an eight-bit value, where the least bit is a “don't

care” value. For example, if the address of a slave device is 0x69, insert D2
or D3. A setting of D2 (1101 0010) or D3 (1101 0011) provides the same
results.

 Read from SMBus Device

– Input the specific slave address and command. For more details regarding

slave addresses, please refer to the “Slave Address” subsection.

– Enter the desired data length in the Read Length data field. Click the Read

option to initiate read/receive operations.

 Write to SMBus Device

– Input the specific slave address and command. For more details regarding

slave addresses, please refer to the “Slave Address” subsection.

– Enter the data to be written in the Input Data data field. Please see Notes 2

and 3 below regarding the Input Data and Write Length data fields.

– Click the Write option to initiate write/send operations.
– The write result is displayed in the Results data field.

 Probe for SMBus Device
 The Probe function enables users to scan for device addresses. Each address

detected is the slave address of devices connected to the SMBus.

 The detected addresses are displayed in the Results date field in eight-bit for-

mat. For example, a slave address of 0x69 is displayed as D2.

Chapter 4 S/W Introduction and Installation

Note! 1. The required value must be specified. If the input value is not

required, the date field will be gray and uneditable.

2. For the Write Length data field, data entered into the Input Data

data field is automatically counted and displayed as the Write
Length value.

3. For the Input Data data field, only [0-9], [a-f], [A-F], and space are

allowed as input characters. When inputting multiple bytes of data,
insert a space between each byte.

Watchdog Timer

Chapter 4 S/W Introduction and Installation

 Time Setting Information

The watchdog timer information is displayed in the upper region of the pop-up
window. This data includes the minimum value supported, maximum and mini­mum delay, event, and reset times in milliseconds. If the input value is outside
the specified range, the SUSI API returns an error/failed message. The mini­mum value supported should be indicated when setting watchdog values. All
watchdog values should be an integer multiple of the minimum value.

Time Setting Example

In the example provided in the above screenshot, the maximum delay time
supported is 255000 milliseconds (ms), the minimum delay time is 0 ms, and
the minimum value (minimum unit) is 1000 ms (1 second). Because every set
value must be an integer multiple of 1000 milliseconds, 1500 milliseconds can­not be set as a time value.

 Delay Time Setting

– Set the delay time to a value within the maximum/minimum delay time range.

For information regarding setting values, please refer to the Time Setting
Information subsection.

 Reset Time Setting

– Set the reset time to a value within the maximum/minimum reset time range.

For information regarding setting values, please refer to the Time Setting
Information subsection.

– When the watchdog timer reaches the specified reset time, the board reset

process will be initiated.

 Event Type and Event Time Setting

– The Event Type options include “None”, “IRQ”, “SCI”, and “Power Button”. If

the Event Type is set as IRQ, SCI, or Power Button, the Event Time will be
configurable. If the Event Type is set as None, an Event Time value is not
required.

51 MIO-2270 User Manual

– Set the event time to a value within the maximum/minimum event time range.

For information regarding setting values, please refer to the Time Setting

Information subsection.

– When the watchdog timer reaches the specified event time, the selected

event type will be triggered. If the Event Type is set as IRQ, a callback func-

tion will be initiated. In the demo program, the callback function prompts a

text box with the message "Get IRQ Event" to be displayed onscreen.

– Some boards do not support the Event Time function. In such cases, the

Event Type and Event Time data fields are disabled.

 Watchdog Timer Control

– Start Timer: After configuring all settings, click the Start button to start the

watchdog timer.

– Trigger Timer: After the watchdog timer is initiated and the delay time is

reached, click the Trigger button to reset/restart the timer.

– Stop Timer: When the watchdog timer is activated, click the Stop button to

stop the timer.
