The Moxa CP-102E is a 2-Port RS-232 serial card for use in industrial automation systems and machine control, connecting to modern PC systems via a PCI Express x1 interface. The card enables data transmission between a computer and serial devices, such as sensors, controls, or monitoring units, communicating via RS-232 interfaces. Due to its high reliability and broad operating system support, it is suitable for professional IT and automation applications.

Applications
The CP-102E is suitable for applications requiring stable serial communication, particularly in automation technology, machine control, and monitoring technology. It enables the integration of legacy devices into modern systems equipped with PCIe interfaces and also supports non-standard baud rates, simplifying adaptation to specific device configurations.

Functions and Features in Detail
The card features two DB9 male connectors, each providing an RS-232 interface. Each port includes an integrated 128-byte FIFO buffer, enhancing data transmission efficiency and reducing buffer overflows at high data rates. LED indicators for transmit (Tx) and receive (Rx) activity per port support fault diagnosis and enable visual monitoring of communication activity.

Technology Explained Simply
The MU860 controller is compatible with the 16C550C standard, a widely used standard for serial communication controllers designed for high data rates and reliable data transmission. The card supports baud rates from 50 bps to 921.6 kbps, including configurable non-standard baud rates. Communication operates with stop bits 1, 1.5, or 2, parity types None, Even, Odd, Space, Mark, and flow controls None, RTS/CTS, XON/XOFF. Signals include TxD, RxD, RTS, CTS, DTR, DSR, DCD, and GND, enabling full RS-232 communication.

Compatibility and Accessories
The CP-102E is certified for Windows (DOS through Windows 10 and Server 2019, x86/x64), Linux (kernel 2.4 to 5.x), and various UNIX derivatives (QNX 6, Solaris 10, UnixWare 7, SCO OpenServer 5/6). The card can be installed up to eight times in a single PC, enabling high scalability for systems with multiple serial devices. Power supply is via the PCIe bus at 520 mA at 3.3 VDC.

Installation and Mounting
The card is installed into a free PCI Express x1 slot of the computer. Installation is performed using the provided drivers for supported operating systems. Mechanical dimensions are 85.04 mm x 100 mm, allowing compact installation in standard PC enclosures.

Operational Advantages
The CP-102E features high operational reliability, with an operating temperature of 0 to 55 °C and a storage temperature of -20 to 85 °C. Relative humidity may range from 5 to 95 %, provided no condensation occurs. The card complies with EMC standards such as EN 55032/24, CISPR 32, FCC Part 15B Class A, and is immune to interference according to IEC 61000-4-x (ESD, EFT, Surge, RS, CS, PFMF). It also meets environmental standards RoHS, CRoHS, and WEEE. The MTBF is 4,947,552 hours according to Telcordia Standard TR/SR, indicating very high service life. The manufacturer's warranty covers 5 years.
