its make PCIE-1756 the best choice for industrial applications.
Board ID Setting
The PCIE-1756 has a built-in DIP switch that helps define each card’s ID
when multiple cards have been installed on the same PC chassis. The
board ID setting function is very useful when users build their system
with multiple PCIE-1756 cards. With correct Board ID settings, you can
easily identify and access each card during hardware configuration and
software programming.
Channel-Freeze Function
The PCIE-1756 provides Channel-Freeze function, which can be enabled
either in dry contact or wet contact mode (selectable by the on-board
jumper). When the Channel-Freeze function is enabled, the last status of
each digital output channel will be safely kept for emergency use. More-
over, you can enable this function through software as it is useful in soft-
ware simulation and testing program.
Reset Protection
When the system has undergone a hot reset (i.e. without turning off the
system power), the PCIE-1756 can either retain outputs values of each
channel, or return to its default configuration as open status, depending
on its on-board jumper setting. This function protects the system from
wrong operations during unexpected system resets.

Programming choices for DA&C cards
You may use Advantech application software such as Advantech
DAQNavi software. On the other hand, advanced users can use register-
level programming, although this is not recommended due to its laborious
and time-consuming nature.
DAQNavi Software
Advantech DAQNavi software includes device drivers and SDK which
features a complete I/O function library to help boost your application
performance. This software is included in the companion DVD-ROM at
no extra charge and comes with all Advantech DA&C cards. The Advan-
tech DAQNavi software for Windows XP/Vista/7 works seamlessly with
development tools such as Visual Studio .Net, Visual C++, Visual Basic
and Borland Delphi.
Register-level Programming
Register-level programming is available for experienced programmers
who find it necessary to write code directly at the level of the device reg-
ister. Since register-level programming requires much effort and time, we
recommend that you use the Advantech DAQNavi software instead.
However, if register-level programming is indispensable, please contact
the technical support team to request the relative information.

• PCIE-1756 DA&C Card
• StartUp or User Manual
• Companion DVD-ROM with DAQNavi drivers included.
The PCIE-1756cards harbor certain electronic components vulnerable to
electrostatic discharge (ESD). ESD can easily damage the integrated cir-
cuits and certain components if preventive measures are ignored.
Before removing the card from the antistatic plastic bag, you should take
the following precautions to ward off possible ESD damage:
• Touch the metal part of your computer chassis with your hand to dis-
charge the static electricity accumulated on your body. Alternatively,
one can also use a grounding strap.
• Touch the anti-static bag to a metal part of your computer chassis
before opening the bag.
• Take hold of the card only by the metal bracket when removing it out of
the bag.
After taking out the card, you should first:
• Inspect the card for any possible signs of external damage (loose or
damaged components, etc.). If the card is visibly damaged, please
notify our service department or our local sales representative immedi-
ately. Do not install a damaged card into your system.
Also, pay extra caution to the following aspects during installation:
• Avoid physical contact with materials that could hold static electricity
such as plastic, vinyl and Styrofoam.
• Whenever you handle the card, grasp it only by its edges. DO NOT
TOUCH the exposed metal pins of the connector or the electronic com-
ponents. .
Note: Keep the anti-static bag for future use. You might need
the original bag to store the card if you have to remove
the card from a PC or transport it elsewhere.
