Chapter 1 Introduction
Board ID Setting
The MIC-3756 has a built-in DIP switch that helps define each card’s ID when multi-
ple cards have been installed on the same PC chassis. The board ID setting function
is very useful when users build their system with multiple MIC-3756 cards. With cor-
rect 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-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. 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 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.
1.3 Applications
