First, a very important warning : The "parallel port" on the Slink-e is not at all like the standard Centronics parallel port you have on your PC. DO NOT ATTEMPT TO PLUG STANDARD PARALLEL PORT DEVICES INTO THE SLINK-E - DAMAGE WILL OCCUR! This said, the purpose of the Slink-e parallel port is to allow electronics hobbyists with some low-speed general purpose digital I/O lines that can be used to control or read the status of their circuits. The following pins on the expansion port are relevant to the parallel port. The digital I/O pins are intended for 5V logic signals only - use at your own risk - you can permanently damage your Slink-e through over-voltage, shorts, or mis-connection of these pins.
