Now the computer does not have a parallel port, the desktop needs to add a PCI-parallel port card, but it is more troublesome to open the chassis, and the compatibility of PCI-parallel port card is not very good. Notebook computers only use USB-parallel ports, and USB-parallel ports sold in the market are only printing ports, which can only be used for printers, and other equipment cannot be used. Our USB-parallel port is a real parallel port. Like the original parallel port of the computer motherboard, it is suitable for all kinds of parallel port equipment, such as: all kinds of parallel port programmers, simulators, downloader, all kinds of parallel port industrial control equipment, all kinds of mechanical equipment controllers, engraving machine controllers, etc.

 

 

IO output supports 5v level, io voltage is about 3.5v, better compatibility

 

The baby needs the buyer's ability to do trouble, because the kit contains all the information, so it is generally not returned. Up to now, it is not compatible and cannot be used for mach3 software. It will have a blue screen, mainly in conflict with mach3.sys driver. Please note that it is best not to buy what you cannot solve.

In order to facilitate users whose computers do not have parallel ports to use the upper parallel ports or continue to use the parallel port programmer, the solution is now provided, mainly using the usb2lpt solution, but the official original circuit production is generally much unsuccessful, so special efforts are made to improve and test the original circuit, and seeprog can now be realized. labtool-48, the c8051 parallel port download line is directly used, and the virtual parallel port parallel port equipment should be used in theory, but it needs a lot of testing, so let's talk about the facts.
