TYPICAL APPLICATIONS
An example application of the ADM2582E/ADM2587E for a full-
duplex RS-485 node is shown in the circuit diagram of Figure 40.
Refer to the PCB Layout section for the recommended placement
of the capacitors shown in this circuit diagram. Placement of the RT
termination resistors depends on the location of the node and the
network configuration. Refer to Application Note AN-960, RS-485/
RS-422 Circuit Implementation Guide, for guidance on termination.
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
receiving end in its characteristic impedance and keep stub 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.
