RS485 connection diagram for a DC1 data collector with
multiple inverters
The DC1 data collector from Delta does not have an integrated
RS485 termination resistor. Depending on where the DC1 is
located in the RS485 series, an external RS485 termination
resistor may need to be connected, see Fig. 7.4, p. 69.
