RS-485 Devices
This section describes several common devices that facilitate the use of
RS-422 and RS-485 in practical applications.
Note: Some of the categories listed overlap because some devices provide several features in
one package. For example, optically isolated RS-232 to RS-422/485 converters are listed in
the RS-232 to RS-422/485 section as well as the Optically Isolated Devices section.
