Moxa CP-168U Series – 8-Port RS-232 PCI Serial Board for Industrial Applications

The Moxa CP-168U Series is a smart, high-performance 8-port RS-232 Universal PCI serial board designed for demanding applications such as POS systems, ATMs, and industrial automation. With a top baudrate of 921.6 kbps and data throughput exceeding 700 kbps, it ensures efficient and stable serial communication.

Each port supports full modem control signals, ensuring compatibility with a wide range of serial devices. The CP-168U is compatible with both 3.3 V and 5 V PCI/PCI-X bus architectures, making it highly adaptable for use in various server systems. A wide-temperature version (CP-168U-T) is also available for rugged environments with temperatures from -40 to +85 °C.

Maintenance is simple thanks to built-in Tx/Rx LEDs for each port, and broad driver support (Windows, Linux, UNIX) facilitates system integration across diverse platforms.
