Parallel Port / Floppy Interfaces
You can configure ETX® parallel port interfaces as conventional PC parallel ports or as an interface for a
floppy-disk drive. You can select the operating mode in the BIOS settings or by a hardware mode-select
pin.
If Pin X3-51 (LPT/FLPY#) is grounded at boot time, the floppy support mode is selected. If the pin is left
floating or is held high, parallel-port mode is selected. The mode selection is determined at boot time. It
cannot be changed until the next boot cycle.

Notes: *To protect external power lines of peripheral devices, make sure that:
- the wires have the right diameter to withstand the maximum available current
- the enclosure of the peripheral device fulfils the fire-protection requirements of IEC/EN60950
