1.2 Product Features
1.2.1 Power Input
The power input of all the iDAQ I/O modules comes from iDAQ chassis through the
DB 15-pin connector. The iDAQ I/O modules would be powered on when the power
of iDAQ chassis is connected. For the power consumption information, please refer
to A4. General for detail information.
1.2.2 BoardID
A board ID can be assigned to the iDAQ chassis by the rotary switch and slot num-
ber. The board ID will be shown in the software and can be used to distinguish mod-
ules. The number shown around the rotary switch is in hexadecimal format. For
example, “A” represent 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 all the detailed information.
1.2.3 Plug and Play Device
iDAQ modules are hot-swappable in iDAQ chassis. The modules are recognized
instantly in the software when they’re plugged into the iDAQ slots, the same when
they are unplugged. Therefore, it’s strongly recommended not to perform this while
the system is in acquisition mode - the system should be in idle mode.
1.3 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 corresponded
driver/SDK package could 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 1.4). After
the selection, click on “start” to begin the installation.

tor program (by accessing Start/Programs/Advantech Automation/DAQNavi/
Advantech Navigator). The settings could also be saved to
2. You can then view the device(s) already installed on your system (if any) on the
Installed Device tree view. If the software and hardware installation are com-
pleted, you will see iDAQ modules in the Installed Devices list.
1.5 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 could be installed via XNavi installer. They could be found
under C:\Advantech\DAQNavi (default directory) after the finishing the installation.

1.6 Application Software DAQNavi MCM
DAQNavi MCM is an application software focusing on high-speed data acquisition,
data monitoring and network access. It provides graphical interface for users to
achieve DAQ configuration, data pre-processing, feature extraction, user-defined for-
mula calculation and the 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 datalog-
ging function is also available in DAQNavi/MCM. All the data could be saved not only
in local storage, but also in remote storage.
By introducing the DAQNavi/MCM, the DAQ system could 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).

2.2 Signal Connection and Pin Assignment
2.2.1 Isolated Digital Input Connection
A digital input channel senses the state of the external sensor or switch, and passes
it through a galvanic isolator to the internal circuit. Figure 2.2 shows the digital input
signal connection.
Figure 2.2 Digital input signal connection.
There are several digital input common (DICOM) pins which are shorted together
inside the device. All digital input signals are referenced to DICOM. Therefore, the
negative terminal of the external voltage sources should be connected to DICOM for
proper operation.
If the input voltage is within OFF or ON state logic level, a logic low (0) or high (1) will
be sensed, respectively. If the input voltage is between the OFF and ON state logic
levels, the result is undetermined, which may be low or high. User should ensure the
ON/OFF state voltages of the sensors or switches meet the required values. Do not
input a voltage higher than the maximum value of ON state logic level or lower than
the minimum value of OFF state logic level. The device may be damaged under such
circumstance. Refer to A1. Isolated Digital Input (iDAQ-731) for OFF and ON state
logic level for the device.
Each digital input channel is equipped with a galvanic isolator, which can withstand a
large continuous voltage between external side and internal side. This prevents inter-
nal circuit from damaging when such fault condition happens.

iDAQ-731_751_763D User Manual 10
2.2.2 Isolated Digital Output Connection
A digital output channel sends a signal through a galvanic isolator to control the ON/
OFF state of a MOSFET switch. The state of the MOSFET switch then decides if the
load is conducting or not. The universal digital output channel supports both sink
(NPN) type and source (PNP) type connection as shown in Figure 2.3.
Figure 2.3 Digital output signal connection.
For a sink type digital output, the current which flows through the load is sunk by the
digital output (DO) terminal, and returns to the external source through the digital out-
put ground (DOGND) terminal. This is shown in Figure 2.4.
Figure 2.4 Sink (NPN) type digital output signal connection.
