The CP-114UL-I-T from Moxa is a 4-port serial card for Universal PCI slots, designed for use in industrial automation and data acquisition systems. It enables communication via RS-232, RS-422, and RS-485 interfaces and is developed for system integrators requiring robust and flexible serial interfaces in existing or new systems. The card features a robust design and high reliability, with the T-model variant offering an extended operating temperature range.

Applications
The CP-114UL-I-T is suitable for applications requiring communication with multiple serial devices such as sensors, controllers, measuring instruments, or industrial peripherals via a common PCI system. Typical use cases include machine control, building automation, process monitoring, and industrial networks where stable and noise-resistant data transmission is required. Support for various serial protocols enables integration of heterogeneous devices within a network.

Functions and Features in Detail
The card features four serial ports connected via a DB44 socket. Each port supports a maximum baud rate of 921.6 kbps, sufficient for fast data transmission in industrial environments. Interface configuration is flexible: data bits can be set between 5 and 8, stop bits between 1, 1.5, and 2, and parity options include None, Even, Odd, Space, and Mark. Flow control can be managed via RTS/CTS or XON/XOFF. An integrated FIFO buffer with 128 bytes ensures efficient data buffering and reduces load on the host computer.

Technology Explained Simply
A key feature is the integrated Moxa Turbo Serial Engine™ chip, which optimizes data transmission. Particularly for RS-485 connections, the ADDC® function provides intelligent control of data flow direction, which is helpful in long cable runs and multipoint networks to avoid data conflicts. The galvanic isolation of 2 kV (available only on I-models) protects the card and host computer from voltage surges and electrical disturbances common in industrial environments. The card is designed for 32-bit Universal PCI (3.3 V / 5 V) and is compatible with PCI and PCI-X buses.

Compatibility and Accessories
The CP-114UL-I-T supports a wide range of operating systems, including Windows (from DOS to Windows 10, including embedded versions), Linux (kernel 2.4.x to 5.x), and various UNIX systems such as QNX, SCO, UnixWare, Solaris, and FreeBSD. Optional accessories include various cables, such as CBL-M44M9x4-50 (DB44 to 4x DB9, 50 cm) or CBL-M44M25x4-50 (DB44 to 4x DB25, 50 cm), as well as CBL-F9M9-150 (DB9 F/M, 1.5 m) and CBL-F9M9-20 (DB9 F/M, 20 cm), enabling connection to different serial devices.

Installation and Mounting
Installation involves inserting the card into a free Universal PCI slot of an industrial PC. The card is compact (64.4 x 130 mm) and fits in standard and compact PC enclosures. Configuration is performed using the provided installation guide, which also covers driver installation and interface parameter settings. Power is supplied via the PCI bus at 5 VDC; power consumption is 465 mA.

Operational Advantages
The card features low power consumption, an extended operating temperature range of -40 to 85 °C (T-model), and high EMI resistance. Certifications to CISPR 32, FCC Part 15B Class B, and IEC 61000-4-2/3/4/5/6/8 (model-dependent) ensure reliable operation in electromagnetically noisy environments. The MTBF is 114,223 hours (according to Telcordia SR332), indicating high longevity and reliability. The card is also RoHS, CRoHS, and WEEE-compliant.

Scope of Delivery
The scope of delivery includes the CP-114UL serial card, a DB9 or DB25 cable (model-dependent), an installation guide, a substance declaration, and a warranty card. The exact cable type depends on the specific model; according to ordering information, the CP-114UL-I-T model is delivered without cable.
