Page 128: Appendix 1 Serial Port 485 Communication Protocol
EDS800 series Service Manual Appendix 1 Serial port 485 communication protocol 1.1 Summarization We provide general RS485/RS232 communication interface in our inverters(such as EDS2000 series， EDS2800 series， EDS1000 series etc.) for the user. Through this communication interface upper device (such as PC, PLC controller etc.) can perform centralized monitor to the inverter (such as to set inverter parameter, control run of inverter, read work state of the inverter) and also long-distance control keypad can be connected to realize various usage requirement of the user.
