Inverter/data logger with RS485 interface
The connection of the inverter/data logger is at the point marked RS485 terminal as shown below.
As connecting cable type J-Y(St)-Y, 2 x 2 x 0,6 mm² or similar is used. The maximum length are 1.000
meters.
1. Connect RX+ of the display with TX+ of the data logger/inverter.
2. Connect RX- of the display with TX- of the data logger/inverter. For this use a twisted pair of
conductors.
3. Connect the GND of the display with the GND of the data logger/inverter. The last wire in the
cable is not needed. Cut this last wire off or use it as an additional GND wire.
Between RX+ and RX-
a 120 Ω terminating resistor is installed.
