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 4000 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
party line data bus. 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. Traditionally, the rTS signal is used as the party line control
to tristate the PC’s transmitter, but in multitasking operating systems like Windows or Linux the only
reliable method is hardware autogating. Brainboxes rS422/485 products implement a state of the art
autogating circuit thus ensuring error free communications in half duplex configuations.
