The RS-485 port features MODBUS-RTU protocol. Multiple modules (up to 128) 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.
