7.4 Communication interface settings
NOTE: The parameters Protocol, Address and Baudrate define only the RS485 communication for the provided
models. For models without RS485, the pages of the Setup Menu are anyway available, but have no effect.
7.4.1 Protocol
The default value is "Mod". The possible permitted values for the parameter are [Mod; duC]. Select "Mod" to set the
Modbus-RTU protocol. Select "duC" to set the ASCII Ducbus protocol.
NOTE: if the Address parameter is set to a value greater than 98 and Protocol is changed from Mod to duC, the
default value (31) will be automatically restored.
For detailed information on Modbus-RTU and ASCII Ducbus protocol specifications, refer to the documents available
at the following link: ftp://ftp.ducatienergia.com/DucatiSistemi/Protocols_Analysers/
After parameter is confirmed, the controller will move to the next parameter setting screen (Address).
7.4.2 Address
The default value is "31" (or the previously-set value). If the Protocol parameter is set to Mod (Modbus RTU) the
permitted range is [1÷247], while if it is set to duC (ASCII Ducbus), the permitted range is [1÷98].
NOTE: if the parameter is set to a value greater than 98 and Protocol is changed from Mod to duC, the default value
(31) will be automatically restored.
If a permitted value is entered, the controller will move to the next parameter setting screen (Baudrate).
7.4.3 Baudrate
The default value is "9.6k". The possible permitted values for the parameter are [9.6k;19.2k;38.4k;57.6k;115k]bps.
NOTE 1: the values to be associated to the parameter are always expressed in bps.
NOTE 2: the value "115k" corresponds to a baudrate of 115.2kbps.
After parameter is confirmed, the controller will move to the next parameter setting screen (Overvoltage alarm
threshold).
