Shenzhen KYL Communication Equipment Co., Ltd
is given to each station. The coordination of communication is controlled by
master station that uses data frames containing address code to transmit data or
command. Slave station will receive all of the data and command and compare
the received address code with local address code. If they are different, the data
will be deserted without 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-200U 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.
