RS232 Standard: RS232 allows point to point communication between 2 devices.
RS422 Standard: RS422 allows one transmitter and up to 10 receivers with data transmitter rates up to 10
megabits per second for distances up to 40 feet and up to 100 Kilobits per second for distances up to 4,000
feet (1219 metres).
To achieve good long distance noise immunity, 2 wires are used to carry each signal, configured as a twisted
pair of cables. The TXD pair and RXD pair are used to carry the data whilst the RTS pair and CTS pair lines are
used for handshaking. Thus 2 twisted pairs are used without handshaking and 4 twisted pair cable is used with
handshaking both these schemes allow full duplex data communications.

RS485 Standard: RS485, based on the RS422 standard allows up to 32 driver/receivers pairs on a standard
load or 128 low load devices per port can be connected. Whilst only one of these should be transmitting data
at any time, the rest can all simultaneously listen to the data. Handshaking is performed by software protocol.
Two twisted pairs form a full duplex system.
Often only one twisted pair cable is used as the TXD and RXD lines are tied together; this is known as
half duplex mode. Brainboxes RS422/485 products implement a state of the art hardware autogating circuit
ensuring error free communications in half duplex configurations.
