RS-485 operates through up to 2,000 metres of screened, twisted-pair cable.
Wiring can be daisy-chained point-to-point, or can be T-tapped or spurred. The
total length of cable in the network should not exceed 2,000 metres. If the
network distances are greater than 2,000 metres, use RS-485 booster units, or
fibre-optic cable. For more information refer to the

The cable is specified in detail inAppendix A “ZP wiring guide” on page 117, but
as a guideline it should be data quality cable with a conductor size of 0.5 mm².
