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,
