  • The mPCIe-COM-2SM features high performance 16C950-class UARTs. Each port is capable of communication speeds up to 921.6kbps in RS-232 (differential modes support 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 16Mbps!).

    RS-232, RS-422, or RS-485 can be software selected, per port, and the selection is stored in non-volatile memory for future use.
