The CP-118U/138U Series from Moxa includes high-performance 8-port serial boards designed for industrial automation, POS terminals, and ATM systems. These Universal PCI boards are compatible with both 3.3 V and 5 V PCI and PCI-X systems, ensuring broad deployment flexibility across server and industrial PC platforms.

The CP-118U offers 8 ports supporting RS-232/422/485, making it ideal for mixed interface environments, while the CP-138U is designed for dedicated RS-422/485 communication, typically found in rugged industrial networks. Both models deliver data rates up to 921.6 kbps and feature 128-byte FIFOs with on-chip hardware and software flow control for smooth, high-throughput performance.

Support for major operating systems like Windows, Linux, and UNIX ensures future-proof compatibility. Built-in LEDs on each port provide clear visual indicators for TX/RX activity, and included management software simplifies configuration and maintenance. A wide-temperature model is also available for harsh environments, capable of operating from -40 to 85°C.
