The Moxa CP-102UL-T is a 2-port universal PCI serial card designed for use in industrial automation environments, point-of-sale systems, and cash dispensers. It features an MD1 low-profile design, making it suitable for compact PC systems, and supports RS-232 interfaces with a maximum data rate of 921.6 kbps per port. The card is equipped with a Turbo Serial Engine™ chip design, offering a 128-byte FIFO memory and support for both hardware and software flow control. Compatibility with 3.3 V and 5 V PCI as well as PCI-X slots enables flexible integration into various PC systems.

Applications

The CP-102UL-T is specifically designed for applications requiring reliable serial communication in industrial or stationary environments. These include POS terminals, cash dispensers, industrial control systems, and other devices communicating via RS-232 interfaces. The wide-temperature version (T-model) allows operation at temperatures from -40 to 85 °C, making it suitable for harsher environments.

Features and Specifications in Detail

The card provides two serial ports with configurable parameters: data rate from 50 bps to 921.6 kbps, data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), and parity types (none, even, odd, space, mark). Flow control can be managed via RTS/CTS (hardware) or XON/XOFF (software). Supported signals include TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND. Each port features integrated LEDs for transmit (Tx) and receive (Rx) status indication.

Technology Explained Simply

The 32-bit universal PCI design allows use in systems operating at 3.3 V or 5 V, increasing compatibility with a wide range of computers. The MU860 chipset (16C550C-compatible) ensures stable and high-performance serial communication. The 128-byte FIFO memory supports efficient data transfer, especially at high data rates, and reduces processor load. RS-232 support is a standard in industrial communication, enabling connection to a wide variety of peripheral devices.

Compatibility and Accessories

The card is compatible with operating systems such as Windows (DOS to Windows 10, including embedded versions), Linux (kernel 2.4.x to 5.x), and UNIX (QNX 6, SCO, UnixWare 7, Solaris 10, FreeBSD). For connecting to external devices, separate cables are available, including CBL-M25M9x2-50 (M25 to 2 x DB9-M, 50 cm), CBL-F9M9-20 (DB9 F to DB9 M, 20 cm), and CBL-F9M9-150 (DB9 F to DB9 M, 1.5 m). The CP-102UL-T is delivered without cables.

Installation and Mounting

The low-profile form factor card is designed for installation in compact computer enclosures. Installation is performed by inserting it into an available PCI or PCI-X slot. Power is supplied via the PCI bus (5 VDC, 93 mA). Installation is supported by a quick installation guide included in the delivery scope.

Operational Advantages

The high reliability of the card is underscored by an MTBF of 576,401 hours (for CP-102UL-T). Certifications according to EN 55032/24, CISPR 32, FCC Part 15B Class B, and IEC 61000-4-2/3/4/5/6/8 ensure good EMC and EMS performance. Compliance with RoHS, CRoHS, and WEEE demonstrates environmental compatibility. The 5-year manufacturer’s warranty provides additional security for operation.

The card is designed for use in environments with humidity levels from 5 to 95 % (non-condensing). Storage temperature ranges from -40 to 85 °C. Physical dimensions are 64.5 x 120 mm, enabling compact installation in small systems.
