MD series modules

How to select MD series modules
    The MD-11M is an input type module featuring a male 37-pin D-sub connector that works with ISO-C64 or PISO-C64 PCI-based digital I/O boards. The MD-12M is an output type module featuring a male 37-pin D-sub connector that works with ISO-P64 or PISO-P64 PCI-based digital I/O boards.

An MD series module is used to extend the I/O distance of PC and PAC
    Since a PC and PAC have many network adapters, they don't really require an MD series module to implement an FRnet network. Therefore, long-distance I/O extension is the best application for MD series modules.
