The Moxa CP-114EL Series includes intelligent 4-port PCI Express boards supporting RS-232, RS-422, and RS-485 serial communication. Designed for industrial applications such as POS systems, ATMs, and factory automation, each port supports baudrates up to 921.6 kbps. With a 128-byte FIFO buffer and on-chip hardware/software flow control, these boards ensure high-speed, stable communication.

The low-profile form factor fits compact PCs, and -I models provide 2 kV galvanic isolation for harsh EMC environments. The boards offer comprehensive OS support including Windows, Linux, and UNIX, and feature built-in LEDs for easy diagnostics.
