The CP-132UL-DB9M from Moxa is a compact Universal-PCI interface card with two serial RS-422/485 ports, specifically developed for use in industrial automation. The card enables reliable data transmission over long distances and is designed for operation in demanding environments. It features an MD1 low-profile format, making it suitable for use in compact industrial PCs. The integrated LEDs for transmit and receive signals support commissioning and maintenance, while comprehensive driver support for various operating systems facilitates integration into existing systems.

Applications
The CP-132UL-DB9M is suitable for applications requiring stable serial communication, such as in process automation, machine control, or data transmission in manufacturing technology. Support for RS-422 and RS-485 enables connection to a wide range of industrial devices, sensors, and controls. The card is particularly suitable for systems using a Daisy-Chain configuration, where up to 31 RS-485 devices can be connected over a distance of up to 1.2 km.

Functions and Features in Detail
The card offers a baud rate from 50 bps to 921.6 kbps, ensuring high transmission speed and flexibility in communication. The integrated 128-byte FIFO buffer ensures efficient data processing and reduces the load on the host computer. The automatic data direction control (ADDC®) for RS-485 ports eliminates the need for manual data direction control, simplifying configuration. The card supports various data formats, including 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 can be managed via XON/XOFF.

Technology Explained Simply
The CP-132UL-DB9M is based on the MU860 chipset, compatible with the 16C550C, and operates via a 32-bit Universal PCI bus supporting both 3.3 V and 5 V, and compatible with PCI/PCI-X. The internal connector is a DB25 socket, connected via an included cable (M25 to 2 x DB9-M, 50 cm) to two external DB9-M connectors. Power consumption is 120 mA at 5 VDC for the standard version, and 490 mA at 5 VDC for the isolated version CP-132UL-I. The card is designed for operation in a temperature range of 0 to 55 °C (standard) or -40 to 85 °C (Wide Temp), and can operate at a humidity level of 5 to 95 % (non-condensing).

Compatibility and Accessories
The card is compatible with up to eight cards per PC and supports a wide range of operating systems, including Windows (DOS to Windows 10, Server 2019, CE 5.0/6.0, XP Embedded), Linux (Kernel 2.4 to 5.x), and UNIX (QNX 6, SCO OpenServer, UnixWare 7, Solaris 10, FreeBSD). Optional accessories include the cable CBL-M25M9x2-50 and the Mini DB9F-to-TB terminal block adapter, which extend connection options.

Installation and Mounting
Installation is performed by inserting the card into a free PCI slot of the computer. The card is connected to the external DB9-M connectors via the included cable. Driver installation is carried out using the provided driver packages for the respective operating systems. The integrated LEDs allow for visual verification of communication activity.

Operational Advantages
The CP-132UL-DB9M offers high reliability with an MTBF of 1,647,832 hours and is specified according to Telcordia SR332. Certifications according to EN 55032/35, CISPR 32, FCC Part 15B Class B, as well as IEC 61000-4-2/3, ensure good EMC and EMS performance. Compliance with environmental standards RoHS, CRoHS, WEEE ensures environmentally compatible manufacturing. The 5-year warranty underscores the product’s quality and durability.

Scope of Delivery
The scope of delivery includes 1 x CP-132UL or CP-132UL-I PCI card, 1 x M25 to 2 x DB9-M cable (for DB9M models), 1 x quick start guide, 1 x substance disclosure table, and 1 x warranty card.
