CIC-800A  
Interface Lab

     An interface is a hardware and software data transmission regulator that controls data exchange between the PC and other peripheral devices, including RS-232C, AT-BUS, IDE, SCSI, ISA, PCI, AGP, IrDA, GPIB, USB, IEEE-1394, Wireless etc... 
    Each interface device inherits different specifications such as transmission rate, data format, protocol and applications. Accordingly, learners can familiarize themselves with each kind of interface devices.
    CIC-800A contains multi-purpose interfaces modules, inclusive of serial port (RS-232C), parallel port (Centronics) and universal serial bus (USB2.0) that can be used for various peripheral devices. Add-on modules are available for experiment purpose. The RS-232C and centronics interface firmware adopt  Atmel's chipset modules, and use Microsoft visual C++ 6.0 as developing tools. 
    The USB 2.0 interface firmware adopts cypress's chipset modules, and uses Microsoft visual C++ 6.0 as developing tools. By learning traditional and popular interfaces, users can reap the benefits. Additionally, we also provide source codes and execution files for further studying.
