C070 Data command source
C071 Baud rate
C072 Node address
C073 Data bits
C074 Parity
C075 Stop bits
C078 Wait time
For inverters on the same network, some settings must match from inverter to inverter. These
include:
• Baud rate
• Data bits
• Parity
• Stop bits
However, the node address on each inverter must be unique, used only once on the network.
