The DataPro 1031-MF serial adaptor
is a connector adaptor with a 9-pin
male (plug) DSUB on one end and a
25-pin female (socket) DSUB on the
other end.
This adaptor is commonly used to
allow the use of a 9-pin female
DSUB with a PC COM port that is
a 25-pin port.
Legacy serial devices were built with
a large number of connection options,
including the standard 9-pin and 25-pin
DSUB connectors. The competing parallel (IEEE 1284)
standard also used a DB25 connector, but
this particular product will not
convert a serial signal to a parallel one (or vice versa).
