4.1 Connecting RS-485 Lines
4.1.1 When installing RS485 line, it is recommended using twisted pair cable. If RS485 line
is 100 meters or longer, only a twisted pair must be used.
4.1.2 The Bus topology is recommended for the RS485 line (see Figure 4). If needed, the
RS485 trunk can be branched with short branches (no longer than 100 meters). Longer
branches shall be made using S2000-PI interface converter (see Fig. 6)
4.1.3 The maximum length of RS485 line is 3,000 meters, if cable of 0.5 mm
used. If cable of 0.2mm
longer than 1,200 meters. The RS485 line can be extended using the S2000-PI interface
converter as shown in Figure 5.
4.1.4 To connect the panel to RS485 interface, please connect A and B lines of RS485
interface to A and B terminals on terminal strip
