Safety Precautions - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from the PC chassis
before manual handling. Do not touch any components on the CPU card or
other cards while the PC is powered on.
Disconnect the power before making any configuration changes. A sudden rush
of power after connecting a jumper or installing a card may damage sensitive
electronic components.

1.1 Overview
This chapter provides an overview of Advantech industrial data acquisition (iDAQ)
modules for iDAQ-815, ranging the product lineups, features and accessories.
iDAQ-815 is an 8-channel RTD input module. It features 24-bit resolution, 400S/s
sampling rate, and supporting most of popular RTD materials. It's suitable for RTD
measurement with high accuracy requirements.
1.2 Product Overview
iDAQ-815
Figure 1.1 Overview of iDAQ-815
1.3 Product Features
1.3.1 Power Input
The power input of all the iDAQ I/O modules come from iDAQ chassis via the DB 15-
pin connector. The iDAQ I/O modules are powered on when the power of iDAQ chas-
sis is connected.
1.3.2 BoardID
A board ID (BID) can be assigned to the iDAQ chassis by the rotary switch and slot
number. The board ID will be shown in the software and can be used to distinguish
modules. The number shown around the rotary switch is in hexadecimal format. For
example, “A” represents 10 in decimal format, and “F” represents 15 in decimal for-
mat. The number assigned to each iDAQ module follows a rule combining the Chas-
sisID and slot number. Refer to section 3.4 for detailed information.
1.3.3 Plug and Play Device
The iDAQ modules are hot-swappable in the iDAQ chassis. The modules will be rec-
ognized instantly in the software (Installed Devices list) when they are plugged into
the iDAQ slots and they can be removed as soon as they are disabled in the soft-
ware. Therefore, it’s strongly recommended to operate these actions whilst the sys-
tem is in idle mode not data acquisition mode.

1.4 Driver Installation
The driver package could be found on Advantech Support Portal (https://www.advan-
tech.com/support). Search for iDAQ on the support portal, then the corresponding
driver/SDK package can be found. You’ll get the XNavi installer after the download
session finishes.
Execute the installer, then it will guide you through the session. You can choose the
device and software components you’d like to install in the system (Figure 1.3). After
the selection, click on “start” to begin the installation.
Figure 1.2 XNavi Installation Interface
1.5 Software Utility
Advantech offers device drivers, SDKs, third-party driver support and application
software to help fully exploit the functions of your iDAQ system. All these software
packages are available on the Advantech website: http://www.advantech.com/.
The Advantech Navigator is a utility that allows you to set up, configure and test your
device, and later store your settings in a proprietary database.
1. To set up the I/O device, you could first run the Advantech Navigator program
(by accessing Start/Programs/Advantech Automation/DAQNavi/Advantech Nav-
igator). The settings could also be saved.
2. You can then view the device(s) already installed on your system (if any) on the
Installed Device tree view. Once the software and hardware installation have
completed, you will see the iDAQ modules in the Installed Devices list.
1.6 Software Development Using DAQNavi SDK
DAQNavi SDK is the software development kit for programming applications with
Advantech DAQ products. The necessary runtime DLL, header files, software man-
ual and tutorial videos can be installed via XNavi installer, which can be found under
C:\Advantech\DAQNavi (default directory) after the finishing the installation.

iDAQ-815 User Manual 4
1.7 Application Software DAQNavi MCM
DAQNavi MCM is an application software focusing on high-speed data acquisition,
data monitoring and network access. It provides a graphical interface for users to
achieve DAQ configuration, data pre-processing, feature extraction, user-defined for-
mula calculation and output settings to upload data. All the settings could also be
saved to a project file for further parameter management. On top of that, the data log-
ging function is also available in DAQNavi/MCM. All the data can be saved not only in
local storage, but also in remote storage.
By introducing the DAQNavi/MCM, the DAQ system can become an IoT-solution-
ready edge device. For more information, please search for DAQNavi/MCM on the
Advantech Support Portal (https://www.advantech.com/support).
1.8 FPGA Code Update
The FPGA could also be updated via the interface in Navigator. However, it isn’t nor-
mal to move on to an FPGA update. Advantech strongly suggests you to consult your
technical support before starting an FPGA update.

2.3 Signal Connection and Pin Assignment
2.3.1 2-Wire RTD Input Signal Connection
Figure 2.2 shows 2-wire RTD input signal connection. The two leads of the RTD are
connected to RTD+ and RTD- terminals. In addition, use short wires to connect
EXC+ to RTD+ and RTD− to EXC− in order to form an excitation current loop.
Figure 2.2 2-wire RTD input signal connection.
The excitation current source (IEXC) flows through internal reference resistor (RREF),
RTD lead 1, RTD resistor (RRTD), RTD lead 2, and to the internal ground as shown
by the red line in Figure 2.2. Assuming both lead-wire resistances are equal (RLEAD),
the measurement result can be calculated as follows.
where
CODEADC is the output code of the ADC,
FSRADC is the full-scale range of ADC (for a 24-bit ADC, it is equal to 224),
VIN is the voltage measured by the ADC, and
VREF is the reference voltage of the ADC.
As can be seen in the equation, the lead-wire resistances cannot be separated from
the RTD and result in measurement errors. To minimize the errors, use lead-wire with
length as short as possible.
2.3.2 3-Wire RTD Input Signal Connection
Figure 2.3 shows 3-wire RTD input signal connection. Connect single-lead end of the
RTD to RTD+ terminal and the other two leads to RTD− and EXC− terminals. In addi-

iDAQ-815 User Manual 8
tion, use short wire to connect EXC+ to RTD+ in order to form the excitation current
loop.
Figure 2.3 3-wire RTD input signal connection.
In 3-wire RTD measurement, two excitation current sources with equal output current
values are used to compensate RTD lead-wire resistances. The first excitation cur-
rent source (IEXC1) flows through internal reference resistor (RREF), RTD lead 1, RTD
resistor (RRTD), RTD lead 3, and to the internal ground as shown by the red line in
Figure 2.3. The second excitation current source (IEXC2) flows through RTD lead 2,
RTD lead 3, and to the internal ground as shown by the blue line in Figure 2.3.
Assuming all lead-wire resistances are equal (RLEAD), the measurement result can
be calculated as follows.
where
CODEADC is the output code of the ADC,
FSRADC is the full-scale range of ADC (for a 24-bit ADC, it is equal to 224),
VIN is the voltage measured by the ADC, and
VREF is the reference voltage of the ADC.
Note that the second line of the equation uses the fact that IEXC1 is equal to IEXC2.
As can be seen in the equation, the measurement result is independent of the lead-
wire resistance, as long as all lead-wire resistances are equal and both current
sources match. Therefore, to minimize measurement errors, use RTD with equal-
length lead-wires and keep two current sources at equal output current values.

Chapter 2 Installation Guide
2.3.3 4-Wire RTD Input Signal Connection
Figure 2.4 shows 4-wire RTD input signal connection. Connect two leads at one end
of the RTD to EXC+ and RTD+ terminals, and two leads at the other end to RTD−
and EXC− terminals.
Figure 2.4 4-wire RTD input signal connection.
The excitation current source (IEXC) flows through internal reference resistor (RREF),
RTD lead 1, RTD resistor (RRTD), RTD lead 4, and to the internal ground as shown
by the red line in Figure 2.4. Assuming all lead-wire resistances are equal (RLEAD),
the measurement result can be calculated as follows.
where
CODEADC is the output code of the ADC,
FSRADC is the full-scale range of ADC (for a 24-bit ADC, it is equal to 224),
VIN is the voltage measured by the ADC, and
VREF is the reference voltage of the ADC.
As can be seen in the equation, the measurement result is independent of the lead-
wire resistance. Unlike in 3-wire RTD measurement, the equal holds true even if
lead-wire resistances do not match for 4-wire RTD measurement.
