4.3.3 Connecting the Expansion Cable: RS-485
Differential
For a multiple-rack expansion system, connect the cable from the expansion port on the
Expansion Transmitter to the Expansion Receivers as shown below. If all the Expansion
Receivers are the Isolated type (IC200ERM001), the maximum overall cable length is
750 meters. If the expansion bus includes any non-isolated Expansion Receivers
(IC200ERM002), the maximum overall cable length is 15 meters.
