FBus

Fbus (for "Fast Bus") is an ANSI/IEEE data bus oriented towards backplanes and cell phones. The standard specifies a way for various pieces of electronic hardware to communicate, typically with one piece acting as master (sending a request), and another acting as a slave (returning an answer). The F-Bus is a bi-directional full-duplex serial type bus running at 115,200 bit/s, 8 data bits, no parity, one stop bit (8N1). Much like a standard RS-232 serial port, F-Bus connections use one pin for data transmit, one pin for data receive and one pin for ground.
