USB Experiment Interface Board Kit The K8055N interface board has 5 digital input channels and 8 digital output channels. In addition, there are two analogue inputs and two analogue outputs with 8 bit resolution. The number of inputs/outputs can be further expanded by connecting more (up to a maximum of four) cards to the PC's USB connectors. All communication routines are contained in a Dynamic Link Library (DLL). You may write custom Windows (XP, Vista, Windows7) applications in Delphi, Visual Basic, C Builder or any other 32-bit Windows application development tool that supports calls to a DLL. Source code examples for Visual Basic, Visual C, Visual C#, Excel, Delphi and Borland C builder are available. Hard- and software are downwards compatible with our previous K8055/VM110 board. Features DIAGNOSTIC / TEST SOFTWARE: separate output / input test clear all / set all function counter function on inputs 1 and 2 with adjustable debounce (max 20kHz depends on total I/O load) analog output set sliders analog input bar-graph indication minimum system requirements: 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor USB 1.1 or higher connection Windows XP or later also available in mounted version: VM110N Specifications 5 digital inputs (0= ground, 1= open) (on board test buttons provided) 2 analog inputs with attenuation and amplification option (internal test 5V provided) 8 digital open collector output switches (max. 50V/100mA) (on board LED indication) 2 analog outputs: 0 to 5V, output resistance 1K5 PWM 0 to 100% open collector outputs max 100mA / 40V (on board LED indication) up to 4 cards can be connected to PC general conversion time: 2ms per command uses Microsoft human interface device (HID) driver, no external driver required. diagnostic software, examples and DLL are downloadable via our website power supply through USB: approx. 70mA dimensions: 5.7 x 3.5 x 0.8"
