The following table configures the communications port of the SJ300 inverter. You can have up 
to thirty-two devices on the serial communications network. The inverters are slaves and the 
computer or digital operator is the master. Thus, all inverters on the serial connection must use 
the same baud rate, data length, parity, and stop bits. However, each device on the serial 
network must have a unique node address. See 

 for more 

information.
