CP-102U/UL is a Smart Universal PCI Multiport Serial Board designed for POS and ATM applications, and for use by industrial automation system manufacturers and system integrators.
CP-102U/UL is compatible with all popular operating systems, and each of its 2 RS-232 serial ports supports data rates of up to 921.6 Kbps, and provides full modem control signals, ensuring compatibility with a wide range of serial peripherals. In addition, CP-102U/UL works with both 3.3V and 5V PCI buses, allowing the board to be installed in virtually any available PC server.

Designed for Standard and Compact-sized Computers

CP-102UL is an MD1 low profile board compatible with 3.3V and 5V PCI bus. The board only requires a 5 VDC power supply. This means that CP-102UL fits any sized host computer, ranging from a shoebox sized PC to standard industrial PCs.

Top Performance with 128-byte FIFO and On-chip H/W, S/W Flow Control

Moxa's more than 17 years of experience is concentrated in the Turbo Serial Engine™ chip, which is designed to provide high performance serial data transmission. Thanks to Turbo Serial Engine™, CP-102U/UL is equipped with a 128-byte FIFO and on-chip hardware, software flow control and burst data mode. These excellent features make CP-102U/UL the top performer among all smart multiport serial boards in the world.

Support for Windows and Linux/UNIX OS Drivers

Moxa continues to support today's mainstream operating systems. CP-102U/UL is no exception. Reliable Windows COM and Linux/Unix TTY drivers are available for use with
CP-102U/UL, and other operating systems, such as Windows XP embedded are also supported for embedded integration applications.

PComm Lite Utility for Easy Management and Software Development

CP-102U/UL's software package includes the PComm Lite utility, which is used to diagnose and monitor the status of installed Moxa serial boards. In addition, PComm Library, with its basic serial I/O and file transfer library, is supplied free for easy software development under Windows.
