“SerIAL CArDS eNgINeereD TO eXCeeD eXPeCTATIONS”

USB to Serial providing two rS422/485 serial ports. Up to 921,600 data transfer rates and the 128 byte

deep transmit and 384 byte receive FIFOS, coupled with 1Mbit line drivers deliver uncompromising

performance on your laptop/PC.

USB to serial is the quick low cost way to connect your computer to a serial comms enabled device.

Boost software gives industry leading functionality and compatibility.

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.

These products do away with traditional issues with USB technology so you can buy with confidence!
