Tx/Rx Modes

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.
