The MB5U is a PC-USB 2.0 high performance and high speed interface BiSS master based on FPGA logic system design. BiSS or SSI sensors can be connected easily to a PC. The USB port supplies the adapter as well as the connected device. The BiSS/SSI communication is accomplished by the RS422 transceiver with clock rates of up to 10 Mbit/sec. A fast realtime data acquisition and communication is controlled by double buffering. The PC-USB adapter can be accessed with different software and APIs.
