EX Bus is a standard of serial data transmission, designed primarily for transmission of operational information between a receiver and other devices connected to it. EX Bus replaces standard of channel values transmission in the form of PPM, and also provides security features, faster response, and bidirectional communication (transmission of EX telemetry). EX Bus also enables transmission of information for remote configuration of connected devices via the DC/DS transmitters.
To the devices compatible with EX Bus protocol belongs for example the Duplex EX receivers and Central Box devices.
