Designing for Secure Digital I/O

August 30, 2004 7:47 am | Product Releases | Comments

Today's system designers are faced with many possible I/O functions that can be included in their design. These range from wireless options such as WLAN, Bluetooth or wideband technologies, to data collection options such as Barcode scanning or RFID readers. One way to manage the many options is to build in a plug or slot that can take many different I/O functions using existing standards to allow the system designer to take advantage o...
