== Operation ==
[[File:Joybus_Bits.svg|thumb|270px]]
The protocol utilizes four types of bits: Zero, One, the Console Stop Bit, and the Controller Stop Bit. Zero, One, and the Controller Stop Bits are 4μs long, while the Console Stop Bit is 3μs. Communication is always initiated by the console, by sending an 8 bit (one byte) command to the device plugged in (not necessarily always a standard controller). A Console Stop Bit will usually follow after this command byte unless there is more data.
