Lalim Parallel Port Control

Lalim Parallel Port Control can control hardware through the parallel port (printer port) and can also control a remote PC parallel port through a network.
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 build 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 k ohm resistor direct to it pin.

METHODS OF CONNECTING

Connect Direct
****************************************
Connect Direct means you use this program on the same PC to control the same PC’s parallel port.
1.Tick the check box on which pin you want it to trigger, (D0- D7). Example tick D2
2.Click Set to in Local Printer Port
3.Now pin number 4 triggers to 5 volt.
4.To reset all pin 2-9 to 0 volt clicks Reset


Connect Through Network
*****************************************
Connect Through Network means you can control both remote PC parallel port through network and controller PC parallel port directly.
1.Install the software on both PC.
2.For remote PC, click connects as server.
3.For Controller PC, connect as client.
4.Run the program on remote PC first. Then run the controller PC.
5.On the Controller PC, enter IP address of the remote PC, then click connect.
