Brainboxes, a leader in serial
and Bluetooth connectivity, today launched its new range of PCI Express
(PCIe) RS422/485 serial cards
. The RS422/485 high speed cards have been
engineered in-house by the Brainboxes technical team and are for use in
industrial automation devices, Point of Sale systems and ATM cash
machines. The RS422/485 cards are manufactured in the UK and will be
available from Brainboxes and their resellers and distributors
worldwide this month.

The RS422/485 boards are an addition to the PCIe RS232 range Brainboxes
launched in January 2008, but provide higher speed operation and
connections up to 4,000 feet., using noise resistant differential pair
driver/recievers. Each serial port has 128 byte FIFOs, 1 MegaBoard data
transfers, with on board Hardware and Software flow control.

RS422 and RS485 are bus systems and up to 32 standard load or 128 low
load devices per port can be connected. RS422 is supported with
dedicated pairs for TxD, RxD, RTS and CTS signals. RS485 systems are
supported in both Full Duplex mode using 2 pairs of wires and in Half
Duplex mode using 1 pair of wires. The Half Duplex mode uses Brainboxes
proven 485 Autogating circuitry for automatically turning the line
around from receive to transmit and back again whenever the PC needs to
send data to devices.
