The SST DN4 DeviceNet PCIe network interface cards (NICs) use a single-source manufacturing process for hardware and software. Applications include automotive and semiconductor automation devices and material handling equipment. These NICs scan DeviceNet signals in 3 to 5 ms, enabling real-time control. By combining master and slave functions, those operations can be executed simultaneously, enabling control schemes that require multiple functions. The NICs provide backward compatibility with DN3 cards for legacy system connections. They are tested to ODVA Vol. 3, v.1.8 standards and support several operating systems and drivers, including Windows XP, Vista, 7 (32 and 64 bit) and 8 (32 and 64 bit).
