Network Communications Settings

The following table lists parameters that configure the inverter’s serial communications
port. The settings affect how the inverter communication with a digital operator (such
as SRW-0EX), as well as a ModBus network (for networked inverter applications). The
settings cannot be edited via the network, in order to ensure network reliability. Refer to
“ModBus Network Communications” on page B-1 for more information on controlling
any monitoring your inverter from a network.
