The CP-104UL and CP-104JU series are smart 4-port RS-232 serial boards for Universal PCI, tailored for industrial automation, POS, and ATM applications. With a maximum data throughput exceeding 800 kbps and individual port speeds up to 921.6 kbps, these boards ensure high-speed communication. They feature 128-byte FIFOs with on-chip hardware and software flow control for optimal performance.

Both series support 3.3 V and 5 V PCI/PCI-X slots, making them adaptable to nearly all modern or legacy PC systems. The CP-104UL uses a DB44 connector with breakout cables, while the CP-104JU offers four individual RJ45 ports. Integrated LEDs for Tx and Rx per port simplify status monitoring. Wide-temperature models are also available for use in demanding environments. Broad OS compatibility—including Windows, Linux, and UNIX—makes these boards a flexible choice for system integrators.
