The CP-118U/138U Series from Moxa includes intelligent 8-port serial boards designed for POS terminals, ATMs, and industrial automation applications. These Universal PCI boards (32-bit, 3.3/5 V, PCI/PCI-X compatible) offer either RS-232/422/485 (CP-118U) or RS-422/485 (CP-138U) interfaces, enabling flexible deployment across a wide range of systems.

With high data throughput (up to 921.6 kbps), 128-byte FIFO buffer, and built-in hardware and software flow control, these boards provide reliable serial communication even under demanding conditions. Built-in Tx/Rx LEDs for each port and included management software simplify ongoing maintenance. The broad driver support for Windows, Linux, and UNIX platforms ensures long-term usability and system compatibility.

For harsh industrial environments, wide-temperature models supporting -40 to +85 °C are also available.
