Claim 0:
1. A one-to-many communication circuit, comprising:
a recommended standard 232 signal transceiver, used to receive a control signal from a main controller and convert the control signal into a first signal conforming to a recommended standard 232 communication protocol;
a main controller area network transceiver, electrically connected to the recommended standard 232 signal transceiver and used to convert the first signal into a second signal conforming to a controller area network communication protocol; and
a plurality of subordinate controller area network transceivers, electrically connected to the main controller area network transceiver and receiving the second signal, wherein the main controller area network transceiver sends the second signal to each of the plurality of subordinate controller area network transceivers, and each of the plurality of subordinate controller area network transceivers is used to convert the second signal into a third signal conforming to the recommended standard 232 communication protocol.
