Designed to extend the 50' limit of RS232, this is a specification for serial data connections between digital terminal equipment (DTE) and data communications equipment (DCE). Signal is balanced. May be either synchronous or asynchronous. 5000' limit.

is standard using full duplex differential signal on two pairs of wires. Maximum range 4000 ft. Maximum speed 10 Mbps.
A full duplex, 4-wire serial connection. It uses "differential" signalling like RS-485 but allows communication in both directions at once. Rarely used for modern equipment.
Balanced electrical implementation of EIA/TIA-449 for high-speed data transmission. Now referred to collectively with RS-423 as EIA-530. See also EIA-530 and RS-423.
RS-422 is a serial data communication protocol that specifies 4-wire, full-duplex, differential line, multi-drop communications. It provides balanced data transmission with unidirectional/non-reversible, terminated or non-terminated transmission lines. RS-422 does not allow multiple drivers, only multiple receivers. Maximum recommended range is 4,000 feet (1200 meters). Maximum recommended baud rate is 10Mbit/s.
provides full-duplex asynchronous point to point communication via two twisted pair. RS422 was designed for greater distances and higher Baud rates than RS232. Data rates of up to 100K bits / second and distances up to 4000 Ft. can be accommodated with RS422. RS422 is also specified for multi-drop (party-line) applications where only one driver is connected to, and transmits on, a "bus" of up to 10 receivers.
A serial device control protocol that allows for computers to control video decks and other hardware. RS-422 is the standard for professional equipment, uses SMPTE timecode and is capable of frame accuracy.
A universal balanced line twisted-pair standard for all long distance (1000 m) computer interconnections, daisy-chain style. (RS-422 pinout)
A physical electrical interface standard established by the Electronic Industries Association (EIA)
Standard defined by EIA, aka. EIA-422. Deals with the electrical characteristics of balanced voltage digital interface circuits. Similar to standard V.11 of CCITT.
This is an advanced format of digital communication when compared to RS-232. The basic difference is in the need for four wires instead of two as the communications is not single-ended as with RS-232, but differential. In simple terms, the signal transmitted is read at the receiving end as the difference between the two wires without common earth. So if there is noise induced along the line, it will be cancelled out. The RS-422 can drive lines of over a kilometer in length and distribute data to up to 10 receivers.
Transmittance standard for serial transmittance of PC data. Unlike RS 232 - standard up to 1.200 m can be bridged with RS 422. The trade offers complying modifiers which can transform a RS 232 signal into a RS 422 standard.
RS-422 provide much longer transmission distance but less signal line compares to RS-232. RS-422 adopts differential transmission technology and thus provides high-speed transmission up to 10Mbps and maximum transmission distance up to 1.2km/110kbps.
This standard specifies voltages and impedance levels on balanced line interconnections. The data is transmitted on a twisted pair of wires (4 wires on a full duplex system). The system uses the difference of potential between the wire pairs rather that the potential with respect to ground as an RS-232C system does.
The second most common communication interface standard which extends beyond the 100 feet limitation of RS-232 data communication supporting a maximum distance of 4000 feet. Serial Communication See RS-232.
An industry standard for a popular serial network protocol used for a variety of applications. NVE makes RS-422 network signal couplers that combine spintronics coupling with network protocol functions in a single small package.
A more robust serial digital data interchange standard utilizing individual differential signal pairs for data transmission in each direction. Depending on data transmission rates, RS-422 can be used at distances to 4,000 feet (1,275 meters). Also referred to as RS-422A (the most popular revision).
Similar to RS-485, the RS-422 standard enables signals to travel greater distances than RS-232 (4000 ft versus 20 ft) with greater immunity to noise. RS-422 employs a pair of wires for transmission, a pair for reception plus a ground wire and an additional pair for each control signal used.
A standard, balanced interconnection scheme for data communication over twisted pair. Designed to work over longer distances, in the range of 3000+ feet.
A recommended standard published by the EIA to specify electrical signal levels of a serial interface. RS-422 uses balanced circuits and is designed to be used with the RS-499 mechanical specifications.
A serial data standard which allows one transmitter to send communication data to up to 10 receivers
An EIA serial digital interface standard that specifies the electrical characteristics of balanced (differential) voltage, digital interface circuits. This standard is usable over longer distances than RS-232. This signal governs the asynchronous transmission of computer data at speeds of up to 920,000 bits per second.
A standard for asynchronous serial communications. Designed for distances up to 4000+ feet.
EIA serial transmission standard that extends transmission speeds and distances beyond those of RS-232. It is a balanced system with a higher level of noise immunity.
The standard adopted in 1978 by the Electronics Industry Association as EIA-422-A, Electrical characteristics of balanced voltage digital interface circuits. A universal balanced line twisted-pair standard for all long distance (~1000 m, or ~3300 ft) computer interconnections, daisy-chain style.
