any response. If 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-500L 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.
