RS422 Full duplex. RS485 4 wire full duplex or 2 wire half duplex with Autogating, automatic
control of data direction. They have 128 bute FIFOs, 1 MegaBoard data transfer, with on board
Harware and Software flow control.
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 configuations.
