Hitachi SJ7002 Series Instruction Manual page 145

Serial
The following table configures the communications port of the SJ700
up to thirty-two devices on the serial communications network. The inverters are slaves and the
Communications
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
information.
