Station Address
Internal address of wireless data station, stations with the same address as those independent of
Modbus address can communicate with each other. This feature can be used to realize software
filtering grouping input range :0~65535, decimal number.
Frequency Channel
It is equivalent to the working frequency of the wireless data transmission station. Each channel
corresponds to its different working frequency. Theoretically, different frequency channels cannot
communicate with each other
，
If there are multiple groups of wireless data stations in the same area,
the communication frequency interval is suggested to be 2~5MHz.
Cipher
function
Only stations with the same ciphertext can communicate, and the secondary ciphertext can only be
written but cannot be read.
Cipher text set Radio ciphertext, input range :0 ~ 65535, decimal number.
