those address codes are the same, it means the data is sent to the local. Slave station
will make different responses according to the transmitted data or command and send
back the data of response. All these jobs must be performed by upper protocol, and it
is assured that there is only one transmitter-receiver in the state of transmission in the
communication network at any instant moment so as to avoid the cross-interference.
KYL-300H can also be used for point-to-point communication with easier operation.
For the programming of serial port, all you have to do is to remember that its
communication mode is semi duplex while always observing the time sequence of
come-and-go for receiving and transmitting.
