Moxa CP-104UL-DB25M ,4 Port RS-232 Univ-PCI LP

The Moxa CP-104UL and CP-104JU Series are advanced 4-port RS-232 Universal PCI serial boards designed for industrial POS, ATM, and automation systems. With a maximum baudrate of 921.6 kbps per port and data throughput over 800 kbps, these boards deliver excellent serial communication performance using 128-byte FIFO and built-in hardware/software flow control.

Compatible with both 3.3 V and 5 V PCI/PCI-X buses, these boards are ideal for legacy and modern systems alike. The CP-104UL features a DB44 connector with breakout cables to DB9 or DB25, while the CP-104JU provides four direct RJ45 ports. Integrated Tx/Rx LEDs on every port assist in diagnostics. Broad OS support for Windows, Linux, and UNIX systems is provided, along with wide-temperature variants for challenging environments.
