PCIe cards support speeds up to 3 Mbits/s

San Diego, Calif. — ACCES I/O Products, Inc. has released a family of isolated PCI Express serial communication cards, which provides 2 kV isolation between channels, and between the PC and bus lines on all signals. Targeted markets include retail, hospitality, automation, gaming, shipboard, and defense industries along with applications such as point of sale (POS) systems and kiosks.

The PCIe-ICM Series cards feature an x1 lane PCI Express connector that can be used in any available x1, x2, x4, x8, x12, or x16 PCI Express expansion slot.

The cards feature a selection of 4- or 2-ports of isolated, software selectable, RS-232, RS-422, and RS-485 serial protocols. Each RS-232 port is capable of supporting data communication rates up to 921.6 Kbits/s 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 3 Mbits/s. Existing serial peripherals can connect directly to industry standard DB9M connectors that are provided on-board each card.

The PCIe-ICM cards were 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, said the company. New systems can continue to use legacy serial peripherals. The cards are fully software compatible with current PCI 16550 type UART applications and allow for users to maintain backward compatibility.

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