Multiple connection method using a single control link

摘要

A multiple connection method using a single channel is provided. The multiple connection method includes the steps of: (a) transmitting polling addresses from the master in a predetermined sequence using the single channel; (b) receiving the polling addresses by each slave using the single channel; and (c) switching on only the transmitting terminal of the slave corresponding to the received polling address, and switching off the transmitting terminals of the other slaves. Therefore, the multiple connection is possible using only a single channel regardless of the number of communication devices commonly connected.
