Most of the time a DB9 male will

usually be a DCE.

PLCs, and most devices that are not
used to extend communications.

A DCE device is "Data Communications
Equipment." This includes modems and
other devices that extend communica-

If both devices have a DB9 male

you will need a crossover cable.
When one device is female and
one device is male, use a
straight-through cable.
