The Moxa CP-114UL Series is a rugged 4-port serial board solution for industrial RS-232/422/485 communication. Designed for PC-based automation and data acquisition, these boards are fully compatible with 3.3/5 V PCI and PCI-X slots and offer high data throughput, advanced RS-485 support via Moxa’s Turbo Serial Engine™ and ADDC®, and optional 2 kV isolation.

The CP-114UL Series supports transmission rates up to 921.6 kbps, 128-byte FIFO, software/hardware flow control, and operating temperatures down to -40 °C (T models), making it ideal for long-distance, multi-drop communication in demanding environments.
