One of the most widespread uses of RS-422 was on the early Macintosh computers. [5] This was implemented in a multi-pin connector that had enough pins to support the majority of the common RS-232 pins; the first models used a 9-pin D connector, but this was quickly replaced by a mini-DIN-8 connector starting with the Macintosh Plus. The ports ...
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 ...

The serial DCD pin can be used to accurately detect a PPS signal, as described in RFC 2783: [1] One convenient means to provide a PPS signal to a computer system is to connect that signal to a modem-control pin on a serial-line interface to the computer. The Data Carrier Detect (DCD) pin is frequently used for this purpose.
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.
Revision A [2] changed these interchange circuits to Category II (para 4.3.6 and 4.3.7 of the standard [3]) and added a "Ring Indicator" on pin 22. Pin 23 is grounded in TIA-530-A. Confusion between the revisions has led to many incorrect wiring diagrams of this interface and most manufacturers still adhere to the original TIA-530 standard.
As feature creep set in, the number of required pins began to grow beyond what a DB-25 could handle, and the RS-449 effort started to define a new connector. 449 emerged as an unwieldy system using a large DC-37 connector along with a separate DE-9 connector if the 422 protocol was used. The resulting cable mess was already dismissed as ...
