Brainboxes - PCI Express (PCIe) Cards - OVERVIEW

 
 
 
Overview_Picture

PCI Express (PCIe) slots are replacing PCI slots within desktop PCs and servers. PCIe cards have a similar form factor and user experience as the older PCI cards, however they are both faster and require less power and are becoming the card type of choice. Brainboxes PCI Express cards will fit in any PCI Express slot - x1, x4, x8 & x16.

Brainboxes manufacture an extensive range of PCI Express cards with 1 to 8 ports, RS232 or RS422/485, low profile or standard height, and with or without cables.

PCI Express RS232 & LPT Range Summary

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.

By providing the PX range Brainboxes has ensured a smooth transition for customers from one technology to the next.

The LPT (Parallel Printer Port) cards allow continued connectivity of existing peripherals while keeping up with the latest technology. As few PCI Express PCs are coming to market with LPT printer ports these cards ensure you benefit from your longterm investment with complete backwards compatibility.

PCI Express RS422/485 Range Summary

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.
