WedgeLink Keyboard Wedges

A keyboard wedge is used when you are trying to get data from some type of measuring device into applications that cannot accept data from a serial port.  A software keyboard wedge reads data from a serial port and passes this data to a PC application in such a manner that the application thinks the data is entered via the keyboard. 

Software and hardware keyboard wedges are used extensively in data acquisition applications that include statistical programs, spreadsheets, barcode, LIMS, etc.  MicroRidge keyboard wedges can accept input data from any RS-232 serial device.  The data is then passed to a Windows application in such a manner that the application thinks the data is actually coming from the keyboard.

Software Keyboard Wedges

The advantage of a software wedge is that it provides much more flexibility in the formatting of data for presentation to the application and control of the target where the data is sent.  In addition to transferring the information to the application, the WedgeLink software keyboard wedge can also simultaneously send the information to a disk file.  The disadvantage of a software wedge is that your software wedge settings can be changed by your users.

Hardware Keyboard Wedges

It is not uncommon in a production type environment that a company will insist upon using a hardware wedge rather than a software wedge.  An advantage of a hardware wedge is that it is simpler to use because it is more like a plug ‘n play device.  In most cases, just plug it in and you are ready to go.
