Modbus-RTU, ASCII, and Modbus-TCP (if using expansion modules ).
The is a multifunction digital power analyzer with a built-in RS485 interface that supports the Modbus RTU protocol. It provides deep visibility into electrical parameters through a comprehensive register map, typically accessed via 16-bit holding registers.
