All three interfaces can be connected to a data acquisition device (Data Logger), to achieve
data exchange with PC or other monitoring devices.
The RS485-1 crimp and the RJ45 interface can be applied to applications where multiple in-
verters communicate in a daisy-chain form.
A 120Ω resistor can be connected in parallel between RS485-1 A/B pins by configuring the
dip switch.
RS485-1 crimp interface and RJ45 interface serve as the same function with differ-
ent wiring manner.
