Four And Two-Port Multi-Protocol RS-232/422/485 M.2 Cards
M.2-COM-4SM Family
-
The M.2-COM-4SM family of cards feature high performance 16C950-class UARTs. Available in 4-port and 2-port versions, 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 10Mbps!).
