Patton's Model 503P and 503PC units are simple to install, and
require no user configuration. Follow these installation steps.
1.
Turn off your PC/printer's power and disconnect the power
cord(s) from the wall outlet(s).
2.
Unplug (disconnect) the existing connection between the
parallel cable and your PC/printer's parallel port(s).
3.
Install the Model 503P between the parallel cable and the DB-
25 parallel port. Install the Model 503PC between the parallel
cable and the Centronics®-36 connector of your parallel
printer. For best results, both protectors should be used–one
at each end of the cable.
