  • The mPCIe-ICM422 family of cards feature high performance 16C950-class UARTs. Available in 4-port (mPCIe-ICM422-4), 2-port (mPCIe-ICM422-2) and 1-port (mPCIe-ICM422-1) versions, each port is capable of communication speeds as high as 3Mbps and has 128-byte deep transmit and receive FIFOs. Large FIFOs protect against data loss in multitasking operating systems, reduce CPU utilization, and improve data throughput, while reducing or eliminating inter-character or inter-packet pauses. The advanced integrated circuit with pre-scalar supports a wide variety of custom baud rates, and any rates not otherwise achievable can be supported via a custom factory-installed crystal oscillator (up to 12Mbps!).

    Tru-Iso port-to-port and port-to-PC isolation provides a robust solution to common signal level and grounding issues when using long cables to connect computers and other powered devices - up to 500V of difference between pins and adjacent ports and 1500V between each port and the host computer.

    The mPCIe-ICM422 Series Features Include:
    • PCI Express Mini Card (mPCIe) type F1, with latching I/O connectors
    • 4, 2, or 1-port mPCIe RS422 serial cards with optional DB9M connectivity
