I have a USB(male)-Centronic printer(male) cable and i want to simulate the LPT port using the USB port of mi laptop for the purpose of using the parallel I/O device of the EasyPLC editor and get 8 digital outputs.
Can it be done?
Or USB to Serial maybe, simulating COM ports and using the Serial I/O device?
Please help
For printer cable I never tested, but should work fine.
For serial cable not problem, I have tested several times with diverse USB to serial adapters and ever work perfectly.
After searching the web and forums: these USB-Parallel adapters only work with parallel input printers because the driver recognizes this printers as USB, the adapter does not emulate the LPT port, thus the EasyPLC parallel I/O driver does not recognize any LPT port :(
the only way to do this in a new PC without a phsysical parallalel port is using a card that creates a new, phsysical parallel port like the PCI and Express cards.
Instead will use the usb-serial adapter ;D thank you EasyPLC_Master
Thanks for the info!
