1. Introduction
This chapter gives background information on the MIC-3756. It then
shows you how to configure the card to match your application and
prepare it for installation into your system.
The MIC-3756 is a 64-channel Isolated Digital I/O CompactPCI™
DAS Card,which complies with PICMG 2.0 R2.1 CompactPCI
specifications.The MIC-3756 features a unique circuit design and
complete functions for data acquisition and control. It is a powerful
data acquisition (DAS) card for the CompactPCI bus.

The Advantech MIC-3756 DAS card offers the following main
features:
Robust Isolation
The MIC-3756 features a robust isolation protection for applications
in industrial, lab and machinery automation. The MIC-3756 can
durably withstand voltages up to 2,500 VDC, preventing your host
system from any incidental harms. Even with an input voltage rising
up to 70 VDC, the input channels of MIC-3756 can still manage to
work properly albeit only for a short period of time.
Wide Input/Output Range
The MIC-3756 has a wide range of input voltage from 10 to 50 VDC,
which is suitable for most industrial applications with 12 VDC, 24
VDC and 48 VDC input voltage. The MIC-3756 also features a wide
output voltage ranging from 5 to 40 VDC, suitable for most industrial
applications with 12 VDC / 24 VDC output voltage. In the mean time,

5
we are also ready to serve your special needs for specific input/output
voltage range. Do not hesitate to ask us about tailoring our standard
products to meet your specifications. All these merits make MIC-3756
the best choice for industrial applications.
Board ID Setting
The MIC-3756 has a built-in DIP switch that helps define each card’s
ID when multiple cards have been installed on the same CompactPCI
system. The board ID setting function is very useful when users build
their system with multiple MIC-3756 cards. With the correct Board ID
settings, you can easily identify and access each card during hardware
configuration and software programming.
Channel-Freeze Function
The MIC-3756 provides Channel-Freezefunction, which can be
enabled either in dry contact or wet contact mode (selectable by the
on-board jumper JP2). When the Channel-Freeze function is enabled,
the last status of each digital output channel will be safely kept for
emergency use. Moreover, you can enable this function through
software as it is useful in software simulation and testing program.
Reset Protection
When the system has undergone a hot reset (i.e. without turning off
the system power), the MIC-3756 can either retain output values of
each channel, or return to its default configuration as open status,
depending on its on-board jumper (JP3) setting. This function

6
protects the system from faulty operations when the system resets
unexpectedly.
1.2 Specifications
•Bus Interface:CPCI bus specification 2.1 compliant

2. Hardware Configuration
This chapter gives users a package item checklist, proper instructions
about unpacking and step-by-step procedures for card installation.
2.1 Initial Inspection
You should find the following items inside the shipping package of
MIC-3756 (in addition to this manual):
•CompactPCIcard MIC-3756
• Advantech Automation Software CD-ROM
• MIC-3756 user’s manual
Prior shipment, we have carefully inspected the CompactPCI card
series. It should be free of marks and scratches and in perfect working
order on receipt.As you unpack the CompactPCI card series, check it
for signs of shipping damages (damaged box, scratches, dents, etc.) If
it is damaged or fails to meet specifications, notify our service
department or your local sales representative immediately, and your
carrier. Retain the shipping carton and packing materials for
inspection by the carrier. Upon inspection, we will make all necessary
arrangements to repair or replace the unit.
When you handle the CompactPCI card series, remove it fromits
protective packaging by grasping the front metal panel. Keep the
anti-vibration packing. Whenever you remove the card from the
CompactPCI system,store it in this package for protection.

10
Note:
Discharge your body’s static electric charge by touching the back of the
grounded chassis of thesystem unit (metal) before handling the board.
You should avoid contact with materials that hold a static charge such as
plastic, vinyl and Styrofoam. Handle the board only by its edges to avoid
static damage to its integrated circuits. Avoid touching the exposed circuit
connectors. We also recommend that you usea grounded wrist strap and
place the card on a static dissipative mat whenever you work with it.

11
2.2 Hardware Installation
Note:
Make sure you first install the driver before installing the card. We
strongly recommend that you install the software driver before installing
the hardware into your system, since this will guarantee a smooth and
trouble-free installation process.
For more information about the driver installation, configuration and
removal procedures for Windows 9X, Windows NT, Windows 2K and
Windows XP, please see the Device Driver Manual.
When installing the MIC-3756 Card, Please make sure the DLL
driver of MIC-3756 installation is completed, you can now go on to
install the MIC-3756card in your CompactPCI system. If you have
any doubt, please consult the user’s manual or related documentation.
Please follow the following steps to install the card on your system.
To install a card:
Step 1: Remove one cover on the unusedslot of your CompactPCI
computerslot.
Step 2:Hold the Card Vertically. Be sure that the card is pointing in
the correct direction. The components of the card should be
pointing to the right-handside and the black handle of the card
should be pointing tothe lower edge of the backplane.
Step 3: Hold the lower handle and pull the handle down to unlock it.
Step4:Insert the MIC-3756card into the CompactPCI chassis
carefully by sliding the lower edges of the card into the card

12
guides.
Step 5:Push the card into the slot gently by sliding the card along the
card guide until J1 meetsthe long needle on the backplane,
then the Blue LED on the front panel of the card will lit.
Note:
If your card iscorrectly positioned and has slid allthe way into the chassis,
the handle should match the rectangular holes. If not, remove the card
from the card guide and repeat step 3 again. Do not try to install a card by
forcing it into the chassis.
Step 6:Now push the card intothe right place, and the Blue LED will
turn off.
Step 7: After the Blue LED is off, push the handle to secure the card
and lock it into place.
Step 8:Because the CompactPCI system can“Hot-Swap”, if your
CompactPCI computer power is onthe system can configure
the card automatically. Once the system finished configuration,
you can find the card informationin the Device Manager.
Note:
If your card is properly installed, you should see the device name of your
card listed on the Device Managertab.
To remove a card:
Step 1:Push the handle down to unlock the card, and the CompactPCI

13
system will automatically uninstall the card configuration.
Step 2: Once the system completes the configuration,the Blue LED
will lit. Now you can slide the card out.
