On PoKeys57CNC v1.0, v1.1 and v1.2 external pull-up resistor must
be used
DB-25 (LPT-port) IO connector
Warning: on PoKeys57CNC v1.1 the pinout is not compatible with the LPT-based stepper drivers since
the physical pin numbering sequence in PoKeys57CNC v1.1 differs from that of a real DB-25
connector. Check the pinout diagrams above.
The connector on the PoKeys57CNC v1.2 is compatible with the LPT-based stepper drivers.
