Chapter 1 General Information
1.1 Introduction
Thank you for buying the Advantech MIC-3758DIO DAS card. The
Advantech MIC-3758DIO card is a powerful data acquisition (DAS) card
for the CompactPCI bus. It features a unique circuit design and complete
functions for data acquisition and control. The MIC-3758DIO card pro-
vide specific functions for different user requirements:
The following sections of this chapter will provide further information
about features of the DAS cards.
1.2 Features
The Advantech MIC-3758DIO DAS card provides users with the most
requested measurement and control functions as seen below:
Digital Output
• 64 isolated digital output channels
• High-voltage isolation on output channels (2,500 VDC )
• Wide output range (5 ~ 40 VDC )
• High-sink current for isolated output channels (90 mA max./Channel)
• Current protect for each port
• Output status read-back
• Digital output value retained after hot system reset
• Programmable Power-Up States

3 Chapter1
Digital Input
• 64 isolated digital input channels
• High-voltage isolation for input channels (2,500 VDC )
• Wide input range (5 ~ 25 VDC )
• High ESD protection (2,000 VDC )
• Digital Filter function
• Interrupt handling capability
• Robust Isolation
• BoardID switch
MIC-3758DIO features robust isolation protection for applications in
industrial, lab and machinery automation. MIC-3758DIO can durably
withstand a voltage up to 2,500 VDC, preventing your host system from
any incidental harms. MIC-3758DIO, if connected to an external input
source with surge-protection, can offer up to a maximum of 2,000 VDC
ESD (Electrostatic Discharge) protections for input channels.
1.2.1 Wide Input/Output Range
MIC-3758DIO has a wide range of input voltage from 5 to 25 VDC, and
it is suitable for most industrial applications with 12 VDC and 24 VDC
input voltage. MIC-3758DIO also features a wide output voltage range
from 5 to 40 VDC, suitable for most industrial applications with 12 VDC
/ 24 VDC output voltage. In the mean time, we are also ready to serve
your special needs for specific input/output voltage ranges.
1.2.2 BoardID Switch
MIC-3758DIO 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
BoardID setting function is very useful when you build your system with
multiple MIC-3758DIO cards. With correct BoardID settings, you can
easily identify and access each card during hardware configuration and
software programming.

MIC-3758DIO User Manual 4
1.2.3 Programmable Power-Up State Function
User-configurable power-up states are useful for ensuring that MIC-
3758DIO powers up in a known state. Power-up states are programmed in
the EEPROM through the driver.
1.2.4 Watchdog Timer Function
The watchdog timer is a software configurable feature used to set critical
outputs to safe states in the event of a software failure. If there is loss of
communication between the application and MIC-3758DIO, if the watch-
dog timer is enabled and MIC-3758DIO does not receive a watchdog
clear software command within the interval time specified for the watch-
dog timer, the outputs go to a user-defined safe state and remain in that
state until the watchdog timer is disabled and new values are written by
the software. After the watchdog timer expires, MIC-3758DIO ignores
any writes until the watchdog timer is disabled. You can set the watchdog
timer timeout period through the WDT register to specify the amount of
time that must elapse before the watchdog timer expires. The counter on
the watchdog timer is configurable up to 232-1 x 100 ns (approximately
seven minutes) before it expires.
1.2.5 Reset Protection
If the system has undergone a hot reset (i.e. system power was not turned
off), MIC-3758DIO can either retain output values of each channel, or
return to its default configuration as power up status, depending on its on-
board jumper setting. This function protects the system from wrong oper-
ations during unexpected system resets.
