Description
The Velleman Inc. USB Experiment Interface Card Module, also known as the VM110 interface board, is a device that allows for digital and analog input and output. It has 5 digital input channels, 8 digital output channels, 2 analog inputs, and 2 analog outputs with 8 bit resolution. Up to four cards can be connected to a PC's USB connectors to expand the number of inputs/outputs. The communication routines are contained in a Dynamic Link Library (DLL) K8055D.DLL, allowing for custom Windows applications to be written in various programming languages. The specifications include 5 digital inputs, 2 analog inputs with attenuation and amplification options, 8 digital open collector output switches, and 2 analog outputs with options for 0-5V or PWM. The device has a general conversion time of 20ms per command and is powered through USB with approximately 70mA. It also includes diagnostic software with a DLL and has dimensions of 5.7" x 3." x 0.8".
The VM110 interface board has 5 digital input channels and 8 digital output channels. In addition, there are two analog inputs and two analog 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) K8055D.DLL. You may write custom Windows (98SE, 2000, Me, XP) applications in Delphi, Visual Basic, C++ Builder or any other 32-bit Windows application development tool that supports calls to a DLL. Source code for Visual Basic, Delphi and Borland C++ Builder included.
