Since launching our PCI Express RS232 range last year we have continually expanded this range on the basis of the great feedback we have received from end users. We have recently expanded the range to include RS422/485 cards and are now ready to release the latest additions.

Our previous edition informed you of our RS422/485 PCI Express serial launch, with the first releases being our 1 & 2 port versions. We are continuing to expand this range and are now ready to release our 4 port versions of these cards:

The RS422/485 boards provide higher speed operation and connections up to 4,000 feet. The cards have 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. They also come with Brainboxes' acclaimed customer support package, including Lifetime Warranty & Support, that makes Brainboxes stand out above other manufacturers and makes us the serial card supplier of choice for companies around the world.
