The CP-114UL-I-DB25 from Moxa is a 4-port serial card for Universal-PCI slots, specifically designed for industrial applications. It supports serial interfaces RS-232, RS-422, and RS-485, and is suitable for use in industrial PCs, POS systems, or remote monitoring tasks. The card offers high data transfer performance with baud rates up to 921.6 kbps, sufficient for time-critical applications. The integrated Turbo Serial Engine™ with ADDC® function enables simplified RS-485 communication, technically comparable to RS-232, thus simplifying configuration and maintenance.

Applications

The card is designed for use in harsh industrial environments where high reliability and long-term stability are required. It is used in systems that rely on serial communication, such as in automation technology, machine control, or monitoring systems. Support for operating systems like Windows, Linux, and UNIX makes it flexible for use in various IT environments.

Functions and Features in Detail

The CP-114UL-I-DB25 features four serial ports, each equipped with a status LED to visually check the operating status. This facilitates maintenance and fault diagnosis. The card supports hardware flow control (RTS/CTS) as well as software flow control (XON/XOFF), stabilizing data transmission and preventing data loss. The 128-byte FIFOs ensure efficient data buffering, reducing CPU load. Serial port configuration is flexible: data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), and parity types (none, even, odd, Space, Mark) are adjustable.

Technology Explained Simply

The card is designed for Universal-PCI slots and is compatible with PCI and PCI-X (3.3/5 V). The 2 kV isolation, integrated in the -I series, protects the card and the host computer from voltage spikes caused by electrical disturbances or overvoltage. This is particularly important in industrial environments with high electrical loads. The operating temperature ranges from -40 °C to 85 °C, enabling use in extreme environments. Humidity tolerance of 5–95 % (non-condensing) indicates resistance to moist conditions. The MTBF (Mean Time Between Failures) is 114,223 hours, indicating high reliability.

Compatibility and Accessories

The card is compatible with a wide range of operating systems, including Windows 95 to Windows 10, Windows Embedded CE/XPe, Linux Kernel 2.4 to 5.x, and various UNIX systems such as QNX, SCO, UnixWare, Solaris, and FreeBSD. As accessories, various breakout cables are available, including the CBL-M44M25x4-50, which splits the DB44 socket into four DB25 connectors. Other options include cables such as CBL-M44M9x4-50 (DB44 to 4 x DB9) or CBL-F9M9-20 (DB9 F/M, 20 cm), which can be used depending on connection requirements.

Installation and Mounting

Installation is performed by inserting the card into a free Universal-PCI slot of a computer. The card is delivered with a breakout cable (DB25) that splits the DB44 socket into four DB25 connectors. Installation is supported by the included Quick Installation Guide and Substance Overview. Power supply is via the PCI slot; power consumption is 465 mA at 5 VDC.

Operational Advantages

The card offers high operational safety due to the 2 kV isolation and extended temperature range. The integrated status LEDs enable quick fault detection. Support for many operating systems and flexible serial port configuration increase application flexibility. The high MTBF and certifications according to EN 55032/35, CISPR 32, FCC Part 15B Class B, as well as IEC 61000-4-2/-3/-4/-5/-6/-8 (model-dependent) confirm suitability for industrial applications.

Scope of Delivery

The scope of delivery includes the CP-114UL-I-DB25 PCI card, a breakout cable (DB25), a Quick Installation Guide, a Substance Overview, and a warranty card.
