RS-422 is a common transport mechanism for RS-232 extenders. These consist of RS-232 ports on either end of an RS-422 connection. Before hard-disk-based playout and editing systems were used, broadcast automation systems and post-production linear editing facilities used RS-422A [ check spelling ] to remotely control the players/recorders ...
This 9-pin RS-422 pinout has become a de facto standard, used by most brands in the broadcast industry. In the new millennium, RS-422 is slowly phased out in favor of Ethernet for control functions. However its simple way to perform troubleshooting means it will stay around for a long time.

RS-423 systems can transmit data on cables as long as 1,200 meters (3,900 ft). [dubious – discuss] It is closely related to RS-422, which used the same signaling systems but on a different wiring arrangement: RS-423 differed primarily in that it had a single return pin instead of one for each data pin.

While NMEA 0183 only defines an RS-422 transport, there also exists a de facto standard in which the sentences from NMEA 0183 are placed in UDP datagrams (one sentence per packet) and sent over an IP network. The NMEA standard is proprietary and sells for at least US$2000 (except for members of the NMEA) as of September 2020.
Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications between a master (e.g. controller) and a slave (e.g. sensor). SSI is based on RS-422 [1] standards and has a high protocol efficiency in addition to its implementation over various hardware platforms, making it very popular among sensor manufacturers.
Because TIA-530 calls for the more common 25 pin connector, it displaced the similar EIA-449, which also uses EIA-422/423, but a larger 37-pin connector. Two types of interchange circuits ("signals" or "leads") between the DCE and DTE are defined in TIA-530: Category I , which uses the balanced characteristics of EIA-422, and Category II ...
FTDI US232R : USB to RS-232 cable. A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232, RS-485, RS-422, or TTL-level UART serial data.
