3.1.4 Configuring Electrical Networks with RS-485 Repeaters
RS-485 Repeater
To increase the number of nodes (>32) in a network or to extend the cable length
between two nodes, segments can be connected together using RS-485 repeaters
to form a network. Figure 3-1 illustrates how several segments can be connected
together with repeaters to create a network.
The RS-485 repeaters support all transmission rates from
9.6 Kbps to 12 Mbps.
