The Moxa CP-104UL-T is a 4-port RS-232 universal PCI serial card designed for use in industrial environments as well as in applications such as point-of-sale (POS) systems and cash dispensers. The card is based on the MU860 communication controller, which is compatible with the 16C550C standard, and supports a maximum baud rate of 921.6 kbps per port. With a data transfer rate of over 800 kbps and a 128-byte FIFO buffer, it is suitable for data-intensive applications. The integrated hardware and software flow control (RTS/CTS, XON/XOFF) enables reliable data transmission, even under high loads.

Applications

The CP-104UL-T is designed for industrial automation, POS systems, and other applications requiring stable serial communication. The card is suitable for use in computers with 3.3 V and 5 V PCI as well as PCI-X slots. The operating temperature range extends from -40 to 85 °C, making it suitable for demanding environments, such as outdoor use or in climatically extreme industrial facilities. The storage temperature is also -40 to 85 °C, and the humidity range is between 5 and 95 % (non-condensing).

Features and Equipment in Detail

The card features a DB44 connector, which can be connected via separate cables to DB9 or DB25 connectors. The CP-104UL-T version is supplied without cables. Integrated LEDs for Tx/Rx per port facilitate visual fault diagnosis. The card supports various transmission parameters: data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), parity (none, even, odd, space, mark), and flow control (none, RTS/CTS, XON/XOFF). The signals TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND are supported.

Technology Explained Simply

The 32-bit universal PCI bus enables universal compatibility with various systems. The FIFO buffer size of 128 bytes ensures efficient data buffering and reduces the load on the processor. The maximum baud rate of 921.6 kbps per port enables fast communication, although the actual speed depends on the hardware used and the application requirements. The card can support up to eight cards per PC, making it suitable for systems with a high number of serial devices.

Compatibility and Accessories

These cables enable connection to various serial devices.

Installation and Mounting

Installation is carried out by inserting the card into a free PCI or PCI-X slot in the computer. The card is designed as a low-profile model, allowing installation in computer housings with limited space. Configuration is performed using the provided quick installation guide. The card is delivered without pre-configured settings, allowing parameters to be adjusted according to the application.

Operational Advantages

The high reliability of the card is demonstrated by an MTBF (Mean Time Between Failures) of 558,961 hours (according to Telcordia TR/SR standard). Certifications according to EN 55032/24, CISPR 32, FCC Part 15B Class B, as well as IEC 61000-4-2/3/4/5/6/8 (for CP-104UL) ensure good electromagnetic compatibility. Environmental certifications RoHS, CRoHS, and WEEE indicate compliance with applicable environmental regulations. The 5-year manufacturer's warranty underscores the product's quality.

The card is designed for use in systems with high requirements for stability and reliability. The broad operating system support and high baud rate make it a suitable solution for industrial applications requiring fast and reliable serial communication.
