TYPICAL APPLICATIONS
Figure 41 and Figure 42 show typical applications of the
ADM2582E/ADM2587E in half duplex and full duplex RS-485
network configurations. Up to 256 transceivers can be connected to
the RS-485 bus. To minimize reflections, terminate the line at the

lengths off the main line as short as possible. For half-duplex
operation, this means that both ends of the line must be
terminated because either end can be the receiving end.
