The CP-104UL/104JU Series by Moxa are 4-port RS-232 Universal PCI serial boards designed for professional applications in POS systems, ATMs, and industrial automation. With a high data throughput of over 800 kbps and a max baudrate of 921.6 kbps per port, they ensure fast and stable serial communication. The boards feature a 128-byte FIFO buffer along with built-in hardware and software flow control.

Compatible with 3.3 V and 5 V PCI and PCI-X buses, they fit into a wide range of PC servers and industrial systems. The CP-104UL uses a DB44 connector with breakout cables (to DB9 or DB25), while the CP-104JU features four direct RJ45 ports. Built-in Tx/Rx LEDs make diagnostics easy. Both series support a wide range of operating systems including Windows, Linux, and UNIX. Wide-temperature models are available for harsh environments.
