RS-422 systems can transmit data at rates as high as 10 Mbit/s, or may be sent on cables as long as 1,200 meters (3,900 ft) at lower rates. It is closely related to RS-423, which uses the same signaling systems but on a different wiring arrangement. RS-422 specifies differential signaling, with every data line paired with a dedicated return ...
RS-485, like RS-422, can be made full-duplex by using four wires. [8] Since RS-485 is a multi-point specification, however, this is not necessary or desirable in many cases. RS-485 and RS-422 can interoperate with certain restrictions. [9] [failed verification]
Maximum user data rate, transmission data depending on driver and line of e.g. RS-422: 10 MHz, 1 km; LVDS: 100 Mbit/s Independent of the applied physical layer CRC secured communication (sensor data and control data secured separately) [ 8 ]

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.
Differential RS-422 signaling is typically preferred when the encoder will output high frequencies or be located far away from the encoder interface, [5] [6] or when the encoder signals may be subjected to electric fields or common-mode voltages, [5] or when the interface must be able to detect connectivity problems between encoder and interface.
The later color video version is RS-170A which shows color burst and the 4 color field sequence of NTSC. The RS-170A version is only a tentative standard, and was never formally adopted.
