Buy any PCI or PCIexpress parallel port card.Check whether your software, especially its hardware access, runs under 64bit Windows (for the future).Check whether your software can handle non-standard port addresses.Check whether your software relies to InpOut32.dll.Otherwise you are bound to old hardware and operating systemsįor the entire lifetime of your equipment. Avoid using closed-source hardware-accessing software, insist upon getting source.Only laptops having an ExpressCard slot are extensible enough. Today we would like to use the new laptops or desktop computers to do this Quickly performed with old PC (with win 98 or XP) having a LPT port, but Then USB2LPT Low-Speed would help, then expect image download time in days. Possibly your hardware requires 5 V signaling.

(saving the data in a HW buffer) and download them on PC.Įxpect image download times in hours, even with high-speed USB2LPT. Integration (pulsing and clearing the ccd array), stop the acquisition My application needs to communicate with the CCD console to start the image Again, for the blind and deaf: It doesn't work for stepper motors, so not for CNC machines.Ī typical boring e-mail conversation … please do not ask the same again and again: > I have to control an old CCD camera with.You may run dedicated stepper motor control software on its 8051 coreĪnd so greatly reduce the impact to the overall PC performance.Īccess to source code of the stepper motor control software is required.

Like direct stepper motor controls (above 100 Hz or so)ĭue to free programmability of the microcontroller used

Synchronous bus connections, like I☬, SPI…Ĭertain equipment categories are excluded from correct emulation:.

slow controls, like for garden, model railway….

The Application Programmer Interface (API)įor direct access to USB2LPT without INPOUT32.DLL or similar.

USB2LPT is a multifunction device but not complete,.

Read this when you plan to purchase: Not recommended for new designs.

This USB2LPT is not suitable for capturing parallel printer data. To a legacy parallel port is available since 2006. The entire circuitry fits into a usual D-Sub shell housing.Ī reverse device called LPTzUSB for connecting a USB printer This makes connection to most hardware - without adapting the software! A parallel port will be Programmer, ATmega, ISP, FPGA, CPLD, JTAG, direct port access emulation, IEEE 1284, IEEE1284Ĭontrary to all other USB→Parallel adapters which can connect to printers only, Keywords: USB, LPT, parallel, parallel port, printer port, converter, adaptor
