DIP switch configuration
The DIP switch specifies the communication data rate and the node address as shown below. It offers a
choice of data rates (125, 250, and 500 kbps) and a choice of node address ranging from 0 to 63. The DIP
switch should be configured before the inverter and the communications card are turned ON. If the switch
is configured when they are turned ON, the new configuration does not go into effect until they are
restarted.
