Lynx EPM-4 Benutzerhandbuch

    Reference – 31 

The EPM-4 includes a standard bi-directional/EPP/ECP compatible LPT port which resides at the 
PC standard address of 378h. The port can be enabled or disabled and interrupt assignments can 
be made via the CMOS setup screen. The LPT mode is also set via the CMOS setup screen.  

This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage. 

The parallel port can be used as a floppy disk interface. Select “FDD” as the LPT mode in CMOS 
Setup and connect a floppy disk drive to the parallel port cable (CBL/CBR-2003) using the 
floppy disk cable (CBL/CBR-2501). The diagram below shows how to connect the drive.
