Radio Baud Rate (40244)
The register contains baud rate used in Radio protocol. All devices which work in the same group
(the same channel) have to have the same baud rate value. Different baud rate values can be used
for RS485 bus and for Radio protocol.
Value Baud rate
0 1200
1 2400
2 4800
3 9600
4 19200
5 38400
6 57600
7 115200
8 200000
Table 12 Radio baud rate selection
Higher baud rate value requires more bandwidth which can occur on adjacent channels.
The table below shows the dependencies between these parameters.
