Most of engineering industry using PC to control hardware with using additional I/O card but with Lalim Parallel Port Control you can use your default printer port controlling external device such as switching on/off light or control electronic devices. What does this program [does is] trigger the parallel port (Printer port) 's data pin by your command. For example when you trigger pin2 , your printer port's pin2 becomes 5 volt . With this 5 volt , you can built your own electronic circuit to drive other external device. You can also built a simple circuit to test it by connect a LED with 1 kohm resistor direct to it pin.

Lalim Parallel Port Control requires a certain knowledge of electronics and if you are not comfortable with a soldering iron, or don't know what a 1k resistor is, then it is probably advisable that you do not attempt to use this program"; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
