The Moxa CP-114EL Series is a range of high-performance 4-port PCI Express serial boards designed for industrial applications such as POS systems, ATMs, and factory automation. Supporting RS-232/422/485, each port delivers speeds up to 921.6 kbps, ensuring robust and fast communication with industrial devices. With 128-byte FIFOs and on-chip hardware/software flow control, the series supports demanding serial workloads.

Thanks to their low-profile design, the boards fit into compact PCs. The CP-114EL-I models include 2 kV isolation for added protection in electrically noisy environments. The series supports all major operating systems, including Windows, Linux, and UNIX, and provides built-in Tx/Rx LEDs for each port for simplified diagnostics.
