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 ...
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.

RS-422 and RS-485 outputs can be implemented as differential TTL. [2] Normal TTL signals are single-ended, which means that each signal consists of a voltage on one wire, referenced to a system ground. [3] The "low" voltage level is zero to 0.8 volts, and the "high" voltage level is 2 volts to 5 volts.
It uses an DE-9 D-Sub connector with 9 pins (hence the name), where bi-directional communication takes place over a four wire cable according to the RS-422 standard. While nowadays all post-production editing is done with a non-linear editing system, in those days editing was done linearly, using online editing. Editing machines relied heavily ...

On a data modem, the carrier's loss equates to the connection's termination. Much like the Ring Indicator signal, on a PC's serial port, changes to the DCD signal state can generate a hardware interrupt that can be captured by the processor any time the DCD signal changes state, preventing the PC from needing to constantly poll the pin.
