Moxa CP-104JU-T ; 4-Port RS-232, RJ45 UPCI Board

The Moxa CP-104UL and CP-104JU Series are intelligent 4-port RS-232 Universal PCI serial boards designed for applications in POS systems, ATMs, and industrial automation. With per-port transmission speeds of up to 921.6 kbps, over 800 kbps data throughput, and a 128-byte FIFO buffer, these boards ensure high-performance serial communications.

The CP-104UL uses a DB44 connector with optional breakout cables (to DB9 or DB25), while the CP-104JU features four direct RJ45 ports. Both support 3.3 V and 5 V PCI/PCI-X buses, making them suitable for installation in a wide range of PC architectures. Tx and Rx activity LEDs are built into each port, and wide temperature models are available for deployment in harsh industrial environments. Support for Windows, Linux, and UNIX makes these boards versatile and developer-friendly.
