This configuration will set the module to use a pre-defined time interval for
Modbus message recognition calculated for each baud rate. This should provide
optimal performance for most applications.
The following guard band timer values will be automatically used by the module
with the default parameter value (Guard Band Timer = 0) is selected:
Baud Guard Band Timer (ms)
110 350
150 256
300 128
600 64
1200 32
2400 16
4800 8
9600 4
19200 2
28800 2
38400 2
57600 1
115200 1
If you still observe a considerable number of communication errors, try to
increase the Guard Band Time value (in milliseconds) until the network
performance is improved.
