PCI Express serial cards

These have been developed in house by the Brainboxes technical team to meet the growing market for PCIe, with slots predicted to be included on more than 250 million motherboards in the coming year. The first new PCIe cards to be launched are eight port cards - the PX-279 (DB9) and PX-275 (DB25) from Brainboxes distributors worldwide. The cards are supplied with Brainboxes’ Serial Solutions software. The PX-279 and PX-275 cards both offer eight RS232 ports to add reliable and high-speed connectivity via any standard PCIe slot (x1, x2, x4, x8 or x16 lane slots). True megabaud line drivers carry information at 921,600 baud, and 32 byte FIFOs with a user definable trigger level ensure the highest levels of data integrity, reducing the likelihood of dropped packets. PCI Express is a 2-way, serial I/O technology that carries data in packets, similar to the way it is transferred over Ethernet. Unlike standard PCI technology, the PCIe bus is no longer a single parallel data bus through which all data is routed at a set rate. PCIe is an assembly of serial, point-to-point wired and individually clocked ‘lanes’ which each consist of two pairs of data lines carrying data upstream and downstream.
