Mini PCIe cards suit harsh environments
Designed for use in harsh and rugged environments, the mPCIe-COM series of mini PCIe multi-port serial communication cards has been released by ACCES I/O Products. Measuring 50.95x30mm, the cards feature a selection of 4 or 2-ports of software selectable RS-232, RS-422 and RS-485 asynchronous serial protocols on a port-by-port basis. Existing serial peripherals can connect directly to industry standard DB9M connectors on the optional breakout cable accessory kits.
The RS-232 mode supports data communication rates of up to 921.6kb/s, while the RS-422 and RS-485 modes support data communication speeds of up to 3Mb/s. The mPCIe-COM cards, which provide ±15kV ESD protection, were designed using type 16C950 UARTs and 128-byte transmit/receive FIFO buffers to decrease CPU loading and protect against lost data in multitasking systems. New systems can continue to interface with legacy serial peripherals but benefit from the use of the high performance PCIe bus. Fully software compatible with current PCI and PCIe 16550 type UART applications, the cards allow users to maintain backward compatibility.
The mPCIe-COM cards are suitable for military, defence and medical applications, among others.To simplify the verification of COM port operation, the cards are offered with a driver support package, which includes a Windows terminal programme for testing COM ports. The cards are compatible with DOS, Linux and 32-bit and 64-bit Windows OSs.
