1. JBus enable
0 = JBus/Modbus communication disabled
1 = JBus communication enabled
2 = Modbus communication enabled
JBus and Modbus protocols are similar except for the
addressing:
JBus: To access register n, use "n" address.
Modbus: To access register n, use "n-1" address.
2. JBus baud rate
0 = 9600 bauds
1 = 19200 bauds
2 = 38400 bauds
3. JBus baud frame
0 = No parity, 1 stop bit
1 = Odd parity, 1 stop bit
2 = Even parity, 1 stop bit
3 = No parity, 2 stop bits
4 = Odd parity, 2 stop bits
5 = Even parity, 2 stop bits
4. JBus timeout
If no JBus request is received for more than the timeout
delay, the unit will be stopped and an alarm will be
activated. If this parameter is configured to "0", the
timeout is ignored
5. Modbus offset
Those parameters are considered only in Modbus
configuration ([P761]=2).

ModbusRegister = Param ModbusOffset –
ParamOffset – 1
Note: If configured Modbus Offset is null, Parameter
Offset is ignored.
For example, “Cool Home Water Setpoint” [P408] which
corresponds to JBus register 0x0198, will corresponds to
Modbus register 0x8007.
