The RS-485 multi-drop mode offers 32 nodes at same current loop bus, and it is recommended
to enable 120ohm line terminator to obtain better data communication reliability in RS-485 bus.
It is not necessary to add extra 120 ohm line terminator on each RS-485 node, just enable the
DIP Switch-4 of line Terminator Resistor of 1
st
and last node of RS-485 bus for reliable current
looping.
Note: the RS-485 2-wire communication speed will downgrade to
57600bps if RS-485 2-wire link distance up to 1.2KM.
