Learn How USB Ports Work...Then Put Them To Work!  - 5 digital input channels
- 8 digital output channels
- 2 analog inputs and outputs
- Diagnostic software & DLL included
Not so long ago the universal answer for external control from a PC was the serial port. It was easy, it was simple, and you really couldn't mess anything up! Then came parallel port outputs for higher speed connections and transfers. What came next? The "Universal Serial Bus" or USB. Everything has gone to USB connections due to their speed, reliability, and plug and play simplicity. In fact, go to an office store and try to find a printer with a parallel port these days! They call those Legacy products...and technology! | SPECIFICATIONS | | 2 Analog Inputs: | Attenuation and amplification, internal test | | 8 Digital Outputs: | Open collector, 50V/100mA, LED indication | | 2 Analog Outputs: | 0-5V at 1K,m PWM 0-100% open collector | | Gen Conv. Time: | 20ms per command | | Power Supply: | Through USB, 70mA approx. | | Software: | Diagnostic Windows software with DLL | | PC Requirements: | Pentium class or higher, USB1.0 or higher, Win98SE, WinME, Win2K, XP | | Dimensions: | 5.7" x 3" x 0.8" |
Well it's time to get hands on experience developing USB interfaces! This board provides everything needed. All communication routines are contained in a Dynamic Link Library (DLL) that is provided along with Windows based diagnostic software. You can also write custom Windows applications in Delphi Visual Basic, C++, or any other 32-bit Windows development tool that supports calls to a DLL. A variety of inputs and outputs are provided that are controlled and monitored with the diagnostic software. Learn USB the fun way, and watch it work! From Velleman. (No dreaded blue screen of death with this one!)
