LPT-Buffer
Parallel Port-Buffer

  • This board is perfect for parallel ports that work at 3.3v and/or deliver a lower amperage signal because it boosts the output signals to 5v at 24mA.
  • The LPT Buffer board can be used for supplying opto-isolated boards that require a 5v supply.  This reduces the load on the parallel port because you only need a low input signal current to control this board. 
  • You need to supply the LPT buffer using a 5V USB port from the PC.
  • Supply TB1 with a 5V from your USB port.
  • It is now possible to use a laptop PC as a cnc machine controller.

 Note: some laptop PC's may not work with Mach 3 Software.
