1. Connecting T/R1+ and T/R1- of inverter RS485 connector to the T/R+ and
T/R- of the data logger respectively.
2. Between two inverters, connecting T/R2+ of first inverter with T/R1+ of next
inverter, and connect T/R2- of first inverter with T/R1- of next inverter.
3. Set terminal resistor switch "ON" of the terminal-end inverter (the last
inverter of the row) only. The others should be set as "OFF".
Setting the Terminal Resistor
Each inverter has built-in terminal resistor, if RS485 is connecting to multiple
inverters or the total communication length is too long to cause the abnormal
communication, please set the terminal resistor switch to "ON" of the last inverter
in the row connection, all other remaining inverters shall switch to "OFF".
