Several parameter settings are necessary to configure serial communications, listed below.
For inverters on the same network, some settings must match from inverter to inverter. These
include:
include:
• Baud rate
• Data bits
• Parity
• Stop bits
However, the node address on each inverter must be unique, used only once on the network.
