PCI Express RS422/485 Range Summary
CONNECT, CONFIGURE, CONTROL YOUR SERIAL DEVICES
Range Description
PCI Express is the latest connectivity standard within PCs. It is based on the existing PCI bus,
but is faster and requires less power. PCI Express (PCIe) slots have replaced PCI slots within
desktop PCs.
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 multi-tasking 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.
