Serial Network
Parameter
Settings

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:

• Baud rate

• Data bits

• Parity

• Stop bits

However, the node address on each inverter must be unique, used only once on the network.
