ASB7220 Twenty (20) Channel ADC USB Control

The ASB7220 USB ADC module contains successive approximation analog to digital converter capable of sampling input at up to 200ksps. Each ADC channel can be programmed for one of four input voltage ranges: 0 to +10V, -5V to +5V, -10V to 0V, and 0 to +2.5V. Each channel can be programmed to average blocks of 2,4,8,16,32,64 or 128 conversion results.
Single unit cost starts at USD$ 195

Most of our customers write their own program for controlling our devices. With our provided API's you can use any programming language that supports DLL so you do not have to learn a whole new language. We provide two types of DLL api, first is the older standard DLL with both mangled calls and "C" calls. The second is the managed Class Library that supports all the new managed languages. Any programming language that supports calls to Windows DLL can also be used to control the cards. The software interface is easy to use from Visual Basic, Visual C# Visual C++ via a standard windows DLL with sample source included. Linux driver support CD available. Each module has an unique serial number string which allows multiple USB boards to be controlled by the host USB controller as individual USB devices.

This software replaces previous versions of module support software. It is a generic package that will provide support for all J-Works USB Modules. It is recommended that any new designs start with this package, and existing designs be moved over, if/when there is windows updates that require changes to the driver or API, the updates will only be made on jwControl CD. Also additional sample applications will be added to this CD only. There will be a larger number then normal revisions to this package, but most will not affect modules already supported, but is updates for modules not currently supported, or new samples. The Version History pdf outline changes
