The Moxa CP-168U-T is an 8-port RS-232 serial card for Universal PCI bus, specifically designed for use in industrial environments with high requirements for operating temperature and reliability. The card enables connection of up to eight serial end devices to a PC server and is suitable for applications in the POS, ATM, automation technology, and system integration sectors. As a Wide-Temperature model, it is designed for operating temperatures from -40 to +85 °C, making it suitable for locations with extreme climatic conditions.

Applications
The CP-168U-T is suitable for systems requiring high serial interface density, such as retail stores with multiple cash register systems, ATMs, or industrial control systems. Support for full modem control signals (TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND) makes the card compatible with a wide range of serial devices with different control requirements.

Functions and Features in Detail
Each of the eight ports features a FIFO buffer of 128 bytes, which enhances data transfer efficiency and reduces buffer overflow. The maximum baud rate is 921.6 kbps, with data throughput exceeding 700 kbps. The card supports various configurations for data bits (5, 6, 7, 8), stop bits (1, 1.5, 2), and parity types (none, even, odd, Space, Mark), as well as flow control methods such as RTS/CTS and XON/XOFF. This flexibility allows adaptation to different serial devices and communication protocols.

Technology Explained Simply
The card is based on the communication controller MU860, which operates with the 16C550C-compatible standard. This ensures reliable and widely used interface control. The 32-bit Universal PCI bus supports both 3.3 V and 5 V and is compatible with PCI-X buses, enabling installation in a wide range of servers and workstations. Power consumption is 180 mA at 5 VDC, which is within the typical range for PCI cards. The integrated Tx/Rx LEDs per port allow for simple visual monitoring of data traffic, simplifying fault detection and diagnostics.

Compatibility and Accessories
The CP-168U-T is compatible with a broad range of operating systems, including Windows (from DOS to Windows 10 including x64 and Embedded CE/XPe), Linux (kernel 2.4 to 5.x), and various UNIX systems such as QNX 6, SCO, UnixWare 7, Solaris 10, and FreeBSD. Optional accessories include various cables (CBL-M62M25x8-100, CBL-M62M9x8-100) and connection boxes (OPT8A, OPT8B, OPT8S, OPT8-M9, OPT8-RJ45), enabling flexible cabling and connection design.

Mounting and Installation
The card is inserted into a PCI slot of the computer. Installation is performed using the included Quick Installation Guide. The maximum number of cards that can be installed per PC is eight, enabling high scalability. Physical dimensions are 82 x 120 mm, fitting standard PCI form factors.

Operational Advantages
High reliability is underscored by an MTBF of 280,854 hours (according to Telcordia TR/SR). The card complies with EMC standards such as EN 55032/35, EMI standards such as CISPR 32 and FCC Part 15B Class B, and EMS standards such as IEC 61000-4-2 (ESD), -4-3 (RS), and -4-4 (EFT). Additionally, it meets environmental standards such as RoHS, CRoHS, and WEEE, and holds KC certification. The integrated LEDs and comprehensive driver support simplify maintenance and integration into existing systems.
