The PMDX-103 is a general purpose signal isolator for the parallel port of an IBM-PC style computer

+Can be used to isolate motor drivers from Rutex, Xylotex, HobbyCNC, and others that have non-isolated logic level inputs.

+Supports all signals present on a standard printer port. (8 data outputs, 5 status input, 4 status output) (Note: Data port cannot operate in bi-directional mode)

+Isolates signals to protect the PC's printer port from ground loops and electrical noise

+All signals will operate at up to 250KHz with signal delays of 1 microsecond or less

+Provides isolation of 10 megaohms or more and up to 2000 volts between equipment and PC.

+Accepts standard Centronics style printer cable for connection from PC.

+Optionally accepts a DB-25 female to 26 pin ribbon transition cable to allow remote mounting of the DB-25 for connection to the PC.

+Standard version provides DB-25 female connector on the equipment side of the isolator

+Optionally available with 26 pin ribbon header on the equipment side of the isolator

+Status inputs are filtered to suppress noise pulses shorter than 100 nanoseconds duration

+Status signals from equipment side are equipped with pull-ups to allow direct connection of switches to be read by the computer.

+The board is powered from the equipment side and accepts regulated 5 volts DC, unregulated 7 to 24 volts DC, or 9 to 12 volts AC

+LED indicator indicates presence of power and proper operation of power isolation inverter
