JSB391 Dual Switch/Digital Input Module

Vital part of just about any control systems is for applicaitons to be able to monitor contact closure type inputs and the JSB391 USB switch/Digital input module provides two (2) channels for this application. The closures can be as simple as mechincal contacts (switches) or open-collector sensors. The JSB391 ships with a pull-up resistor in a socket between the +In and USB 5V, so when a switch or contact is connected between +In and Ground, the state of the switch can be detected. If the resistor is removed then input can sense the DC voltage and when that voltage is about 3.5V indicate a high, and when below indicate a low. There is 400ma of 5V available for sensor power. When a mechanical contact or switch is used it does not any other electrical connections besides the JSB391 to it can safely be connected to gnd with using a series resistor. Standard module has high quality screw tpe terminal blocks. Single unit cost starts at $48.5 . JSB391 Dual Switch/Digital Input Module

Software
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

On some installations of Windows 7 and Windows 8 that are not configured to search the CD for drivers, it may show driver
not install and you need to do a manual install. If there is not yet a custom install under software downloads
you can download the pdf and zip of the generic install and copy your existing driver files from the CD, or do a manual install from PDF
