Communication function
Communication circuit for RS485/RS23/CAN is built in N700 Inverter.
It is possible to control 1~32 Inverters (Slave) from a main control device (Master) by using RS485
serial communication. Standard RS232 and CAN communication is supported. (note1)

[RS485 port specification and connection]
Serial communication is possible from the communication terminal J2 of the inverter to any
external equipment using RS232/485 protocol.
