The Moxa CP-104UL and CP-104JU Series are high-performance 4-port RS-232 Universal PCI serial boards engineered for POS systems, ATMs, and industrial automation. Each port supports baudrates up to 921.6 kbps, with over 800 kbps actual data throughput. A 128-byte FIFO buffer, along with built-in hardware and software flow control, ensures fast, efficient serial communication.

These boards are fully compatible with 3.3 V and 5 V PCI and PCI-X slots. The CP-104UL features a DB44 connector with optional breakout cables (DB9 or DB25), while the CP-104JU provides four RJ45 ports. Tx and Rx LEDs are built into each port for easy monitoring. With support for major operating systems and wide-temperature models available, this series is well-suited for mission-critical deployments.
