The Moxa CP-102U is a 2-Port RS-232 Universal PCI serial card, specifically designed for use in industrial environments, Point-of-Sale systems (POS), and automated teller machines (ATM). The card is designed for operation in computers with 3.3 V and 5 V PCI- as well as PCI-X buses, enabling high compatibility with various system generations. The integrated Turbo Serial Engine™ technology ensures a data transfer rate of up to 921.6 kbps, with full modem signal support. The CP-102U features two serial ports with DB9 male connectors and is manufactured in the standard form factor.

Applications

The card is designed for applications requiring reliable serial communication in demanding environments. These include industrial automation systems, POS terminals, cash dispensers, and other devices accessed via RS-232 interfaces. The high operating temperature range of 0 to 55 °C for standard models and -40 to 85 °C for wide-temperature models (-T) makes it suitable for harsher environments. The humidity range of 5 to 95 % (non-condensing) covers typical operating conditions in indoor and outdoor settings.

Features and Equipment in Detail

The CP-102U is based on the MU860 controller, compatible with the 16C550C standard. This ensures broad support for various operating systems. Serial communication includes baud rates from 50 bps to 921.6 kbps, data bits in lengths of 5, 6, 7, and 8, stop bits of 1, 1.5, and 2, and parity types None, Even, Odd, Space, and Mark. Flow control is achieved via RTS/CTS or XON/XOFF. Signals TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND are fully supported. Each port features integrated LED indicators for transmit (Tx) and receive (Rx), visually displaying the operational status.

Technology Explained Simply

The card uses a 32-bit Universal PCI bus, supporting both 3.3 V and 5 V voltages. This allows use in both older and modern computers. The FIFO buffer size of 128 bytes ensures efficient data transfer and reduces processor load. The MTBF (Mean Time Between Failures) is 574,050 hours, indicating high reliability. Power consumption is 93 mA at 5 VDC, within the typical range for PCI cards.

Compatibility and Accessories

The card supports a wide range of operating systems, including Windows (DOS to Windows 10 / Server 2019, Embedded CE, XP Embedded), Linux (Kernel 2.4 to 5.x), and UNIX (QNX 6, SCO, Solaris 10, UnixWare 7, FreeBSD). Optional accessories include cables, such as an M25 to 2x DB9-M cable (CBL-M25M9x2-50) and DB9 extension cables in lengths of 20 cm and 1.5 m. These enable flexible adaptation to different connection configurations.

Mounting and Installation

The CP-102U is supplied in the standard form factor and is designed for standard PCI slots. Installation involves inserting the card into the appropriate slot and subsequent configuration using the provided drivers. The quick installation guide included in the package supports installation and configuration. The card is designed for use in computers with 3.3 V and 5 V PCI- and PCI-X buses.

Operational Advantages

The card offers high reliability due to its long MTBF and robust construction. Broad operating system support and flexibility in power supply increase its range of applications. The integrated LEDs simplify troubleshooting and operation. Support for full modem signals and high baud rates makes the card suitable for demanding communication tasks. The 5-year manufacturer's warranty underscores the product's quality and longevity.

Certifications

The card complies with EMC requirements according to EN 55032/24 and CISPR 32, as well as FCC Part 15B Class B. Immunity is certified according to IEC 61000-4-2/-3/-4/-5/-6/-8/-8. Environmental standards RoHS, CRoHS, and WEEE are also met, ensuring environmental compatibility and recyclability.

Scope of Delivery

The scope of delivery includes the CP-102U card, for the CP-102UL variant additionally an M25 to 2x DB9-M cable (50 cm), a quick installation guide, a material declaration, and a warranty card. The cables and documents are intended for immediate use and support installation and operation.
