Figure 6.
Schematics of RS-422 Line with the Point-To-Point Topology.
Note:
The line utilizes two shielded pairs (see Chapter 3.7.). The termination resistors
on the driver side are not necessary when using the standard mode. When using
the multimaster mode, the requirements are analogical to the RS-485 line.
Figure 7. Schematics of Typical RS-485 Line with the Point-To-Point Topology.
Note:
The line utilizes one shielded pair (see Chapter 3.7.). The termination resistors
are shown as passive here, but at least one of them should have active topology
(see Figure 4.).
