PCI Express cards allow DB9 and RJ45 connectivity

Acces I/O Products has released the PCIe-COM range of serial communication cards for use in retail, hospitality, automation, gaming, point-of-sale systems, kiosk design and defence industries.

The PCI Express cards feature both DB9 and RJ45 connectivity and a selection of eight, four or two-ports of software-selectable RS-232, RS-422 and RS-485 serial protocols.

The cards feature a x1 lane PCI Express connector, which can be used in any available x1, x2, x4, x8, x12 or x16 PCI Express expansion slot.

Each RS-232 port is capable of supporting data communication rates up to 921.6kbps and implement full modem control signals to ensure compatibility with a broad variety of serial devices.

RS-422 and RS-485 modes support data communication speeds up to 3Mbps.

Existing serial peripherals can connect directly to industry-standard DB9M or RJ45 connectors, which are provided on-board each card or via a breakout cable.

The PCIe-COM range was designed using type 16C950 UARTS and use 128-byte transmit/receive FIFO buffers to decrease CPU loading and protect against lost data in multitasking systems.

New systems can continue to use legacy serial peripherals, yet benefit from the use of the high-performance PCI Express bus.

The cards are fully software compatible with current PCI 16550 type UART applications and allow users to maintain backward compatibility.

Available accessories include cables, screw terminal boards and breakout connection boxes for a variety of connectivity options.
