The Moxa CP-118U is an intelligent, 8-port universal PCI interface card designed for demanding serial communication tasks in industrial environments, POS systems, and ATM applications. The card is designed for use in PC systems with 3.3 V or 5 V PCI and PCI-X slots, offering high compatibility with various computer platforms. As a universal PCI card, it enables connection of multiple serial devices via a single PCI slot, thereby making the system architecture more efficient.

Applications
The CP-118U is particularly suitable for applications requiring a high number of serial interfaces, such as in automation technology, industrial controls, logistics, or point-of-sale systems. Support for RS-232/422/485 enables connection to a wide range of devices, including sensors, printers, terminals, and other industrial communication endpoints. The card is also suitable for use in environments with higher requirements for reliability and operating temperature, especially in variants with an extended temperature range.

Functions and Features in Detail
The card features eight serial ports, each equipped with a 128-byte FIFO, to prevent data loss at high transmission rates. The maximum data rate is 921.6 kbps, which is sufficient for many industrial applications. Supported data formats include 5, 6, 7, or 8 data bits, 1, 1.5, or 2 stop bits, and parity types such as None, Even, Odd, Space, and Mark. Flow control is supported both via hardware (RTS/CTS) and software (XON/XOFF), ensuring stable data flow even during peak loads. Each port is equipped with separate Tx and Rx LEDs to visually indicate data traffic.

Technology Explained Simply
The CP-118U uses RS-232/422/485 interface standards, where RS-232 is suitable for short distances and simple device connections, while RS-422 and RS-485 were developed for longer distances and robust industrial environments. The RS-485 interface can operate in both 2-wire and 4-wire modes, allowing for flexible configurations. The card provides comprehensive modem control signals required for communication with modems or other serial devices. Power is supplied via the PCI bus at 5 VDC, with power consumption ranging from 240 mA to 300 mA depending on operating mode (RS-232 or RS-422).

Compatibility and Accessories
The CP-118U supports a wide range of operating systems, including Windows 95 through Windows 10, Server 2019, various Linux kernel versions (2.4 to 5.x), and UNIX systems such as Solaris 10, SCO OpenServer, UnixWare 7, QNX, and FreeBSD. This ensures high flexibility when integrating into existing IT infrastructures.

Installation and Mounting
Installation is performed by inserting the card into a free PCI or PCI-X slot of the host computer. Physical dimensions are 82 x 135 mm, fitting standard PCI form factors. The card is powered via the PCI bus, so no additional power supply is required. Driver installation is done using the provided software packages, available for supported operating systems.

Operational Advantages
The high reliability of the CP-118U is underscored by an MTBF of 1,073,385 hours (according to Telcordia SR332). The card is designed for use in environments with an operating temperature range of 0 to 55 °C, with optional models available with an extended temperature range of -40 to 85 °C. Certifications according to EN 55032/35, CISPR 32, FCC Part 15B Class B, and IEC 61000-4-2 to -4-8 ensure electromagnetic compatibility and immunity required for industrial applications. Compliance with RoHS, CRoHS, and WEEE demonstrates the environmental compatibility of the product.

Scope of Delivery
The scope of delivery includes the CP-118U interface card, a quick start guide, a warranty card, and a substance declaration. The card is therefore immediately ready for use once the drivers are installed.

Warranty
The card comes with a 5-year manufacturer’s warranty, highlighting the high quality and reliability of the product.
