Notes:
If your computer doesn’t have the DB9 communication interface, you can use
RS232-USB cable to achieve this function.
One inverter can only be communicated with one PC at the same time through RS-232 port. Thus this
method is generally used for three inverter’s communication, for examples, software updating and
serviceman’s testing.
