ADDC® function

The CP-114UL series from Moxa is an industrial serial card with four ports, designed for use in industrial automation environments. The card supports the serial standards RS-232, RS-422, and RS-485 and is designed for operation in 32-bit universal PCI bus slots that support both 3.3 V and 5 V voltage. It is suitable for use in PCI and PCI-X systems and enables a data transfer rate of over 700 kbps with a maximum baud rate of 921.6 kbps. The card is designed for use in data-intensive applications where high reliability and stability are required.

Applications

The CP-114UL is suitable for applications requiring robust serial communication across multiple devices, such as in machine control, process automation, building automation, or production monitoring. Support for various serial protocols enables integration into existing systems based on RS-232, RS-422, or RS-485. The card is particularly suitable for environments requiring high electromagnetic immunity and mechanical robustness.

Features and Specifications in Detail

A key feature of the CP-114UL is the integrated Moxa Turbo Serial Engine™ with ADDC® (Automatic Data Direction Control), which enables precise control of RS-485 transmit and receive behavior. This is especially important in bidirectional communication links to avoid data loss or collisions. The card features a 128-byte FIFO buffer, which improves data buffering and enhances data transfer efficiency. The integrated Tx/Rx LEDs for each port allow visual monitoring of communication status, which is helpful for troubleshooting and maintenance.

Technical Explanation

The card uses a communication controller MU860, compatible with the 16C550C standard, representing a widely used and reliable interface for serial communication. The DB44 socket on the card enables connection to external devices via standardized cables. The galvanic isolation of 2 kV is integrated in the CP-114UL-I series models, protecting the card and host computer from voltage spikes caused by electrical interference or overvoltage. This is especially important in harsh industrial environments where high electrical loads occur.

Installation and Mounting

Installation is performed by inserting the card into a free PCI or PCI-X slot of an industrial PC. The card is available for installation in standard and wide-temperature models, with standard models supporting an operating temperature of 0 to 55 °C and wide-temperature models supporting -40 to 85 °C. Storage temperature is -40 to 85 °C. Humidity is 5 to 95 % (non-condensing). The card is designed for use in industrial environments subject to high mechanical and electrical stress.

Operational Advantages

The CP-114UL offers high reliability and stability thanks to the integrated Turbo Serial Engine™ and galvanic isolation in the I models. Broad operating system support enables flexible integration into existing system landscapes. The integrated LEDs simplify diagnostics and maintenance. The high MTBF of 114,223 hours (Telcordia SR332) underscores the long life and reliability of the card. The card comes with a 5-year manufacturer's warranty, highlighting its quality and durability.

Scope of Delivery

The scope of delivery includes the CP-114UL or CP-114UL-I card, an M44 to 4 x DB9-M or DB25-M cable (model-dependent), a quick installation guide, a substance declaration table, and a warranty card.
