The RS-485 port features MODBUS-RTU protocol. Multiple modules can be paralleled on the same RS-
485 bus for data transfer to automation or building management systems.
The RS-485 port provides also a good solution for distant PC connection where RainbowPlus program
will enable programming, control and monitoring.
For more details about programming, control and
monitoring through RS-485 port, please refer to
RainbowPlus user manual.
The Modbus register list is given in chapter 22 of this
document.
