ProMinent DULCO turb C Series User Manual

RS-485
The RS-485 digital interface (2 leads / half duplex) is characterised by a very
high tolerance to electromagnetic interference due to the symmetrical signal
transmission. This means that cable lengths of up to 900m can be used. The
final device on a bus must be equipped with a 120 ohm resistor, in order to
avoid signal overlapping.
In order to avoid damage, only separate and connect the RS-485 cable if the
DULCO
®
turb C is switched off.
