The NI VXI-USB Remote Controller bridges VXI (VME eXtensions for Instrumentation) systems and USB-equipped computers, functioning as a Slot 0 capable device within VXI mainframes. This single-slot C-sized module translates between USB and VXI protocols, enabling remote operation and data acquisition from distributed VXI instruments. USB 2.0 connectivity delivers sustained throughput of 32 MB/s between computer memory and the VXIbus, with support for VXIbus Specifications 2.0 and 3.0 features including A64 addressing and 2eVME protocol.
