The CP-114UL Series by Moxa is a high-performance 4-port serial board designed for use with Universal PCI slots, supporting RS-232, RS-422, and RS-485 communication. It is tailored for system integrators in industrial automation and PC-based data acquisition scenarios.

Equipped with Moxa’s Turbo Serial Engine™ and ADDC® for intelligent RS-485 control, it simplifies multipoint communication across distances up to 1.2 km. Optional 2 kV isolation ensures electrical protection for sensitive environments. A wide-temperature version expands usability in extreme conditions.

With broad OS compatibility, low power consumption, and built-in LED indicators, the CP-114UL Series is a robust, flexible solution for industrial connectivity challenges.
