The Moxa CP-102U-T is a 2-Port RS-232 serial card in standard PCI format, specifically developed for industrial and embedded applications. It enables serial communication over two independent RS-232 interfaces and is designed for use in systems such as POS terminals, bank ATMs, or automation installations. The card is characterised by high reliability and broad compatibility with various operating systems. As a -T model, it offers an extended operating temperature range, making it suitable for demanding environments.

Applications

The CP-102U-T is intended for applications in industrial automation, retail and banking technology, as well as embedded systems. It is particularly suitable for devices accessed via serial interfaces, such as printers, scanners, sensors, or industrial controls. Its robust construction and EMC certification also make it suitable for environments with electromagnetic interference.

Functions and Features in Detail

The card features two serial ports with DB9 male connectors, enabling communication according to the RS-232 standard. The maximum baud rate is 921.6 kbps, and the card supports all common data formats: data bits from 5 to 8, stop bits 1, 1.5, or 2, and parity types including None, Even, Odd, Space, and Mark. Flow control can be managed via RTS/CTS or XON/XOFF. A 128-byte FIFO buffer ensures efficient data transfer, supported by the Turbo Serial Engine™, which provides stable and fast serial communication. Each port includes LED indicators for transmit (Tx) and receive (Rx) to enable visual monitoring of operation.

Technology Explained Simply

The CP-102U-T operates with a 32-bit Universal PCI bus, supporting both 3.3 V and 5 V PCI and PCI-X slots. The integrated MU860 controller is compatible with the 16C550C standard, ensuring broad driver support. The card requires a power supply of 93 mA at 5 VDC. The operating temperature range for the -T model is -40 to 85 °C, making it suitable for use in extreme environments, such as outdoor installations or industrial facilities with high heat generation. The storage temperature is also -40 to 85 °C, and the relative humidity range is 5 to 95 %, non-condensing.

Compatibility and Accessories

The card is compatible with a wide range of operating systems, including Windows (DOS through Windows 10/Server 2019, x86/x64, Embedded CE/XPe), Linux (kernel 2.4.x to 5.x), and various UNIX systems such as QNX 6, SCO OpenServer, UnixWare 7, Solaris 10, and FreeBSD. Optional accessories include breakout cables (CBL-M25M9x2-50, 50 cm) and DB9 extension cables (CBL-F9M9-20, 20 cm; CBL-F9M9-150, 1.5 m), which expand connection options.

Installation and Mounting

The CP-102U-T is inserted into a standard PCI slot in the computer. Installation is guided by the included quick start guide, which outlines the necessary setup steps. The card is Plug-and-Play compatible and does not require additional driver installations when used with supported operating systems. Physical dimensions are 80 x 120 mm, allowing installation in standard PC enclosures.

Operational Advantages

The high MTBF (Mean Time Between Failures) of 574,050 hours (according to MIL-HDBK-217F) highlights the card’s high reliability. EMC certification according to EN 55032/24, CISPR 32, and FCC Part 15B Class B, as well as EMS certification according to IEC 61000-4-2 to -4-8 (including ESD, Surge, EFT) ensures stable performance even in electromagnetically noisy environments. The 5-year manufacturer’s warranty provides additional operational security. The card is RoHS, CRoHS, and WEEE compliant, ensuring environmental compatibility.
