Default setting:
Baudrate: 9600
Databits: 8
Parity: 0
Stopbit: 2
Protocol: Modbus Master
Default setting:
Baudrate: 9600
Databits: 8
Parity: 0

Protocol: SCP (WIB)
Configuration of the interfaces RS4852 and RS4853
The parameters of the RS4852 (BMS bus) and RS4853
(component bus) interfaces can be configured.
This is necessary, if Modbus components must be control-
led by RS4853, which only can be configured by Modbus
and which does not work with fixed settings (9600 8n2
for RS4853).

Explanation of indexed parameters:
1 - The change of parameters becomes effective only by
this command. This allows you to change several parame-
ters at the same time.
2 - 0 = no protocol
1 = SCP (WIB)
2 = Modbus Slave
16 = Modbus Master
