CP-104JU V2 Series

CP-104JU V2 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-104JU V2 is compatible with all popular operating systems, and each of its 4 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-104JU V2 works with both 3.3V and 5V PCI buses, allowing the board to be installed in virtually any available PC server.

Top Performance with 128-byte FIFO and On-chip H/W, S/W Flow Control
Our 17 plus years of experience in serial board design is now concentrated in Moxa's new top performance serial data transmission chip, called Turbo Serial Engine™, which equips the CP-104JU V2 series board with a 128-byte FIFO, on-chip hardware and software flow control, and burst data mode. This makes CP-104JU V2 the top performing smart multiport serial board in the world.

Support for Major Windows and Linux/UNIX OS Drivers
Moxa continues to add support for today's mainstream operating systems, and CP-104JU V2, which supports reliable Windows COM and Linux/UNIX TTY drivers, is no exception. In addition, other operating systems, such as embedded Windows XP and QNX, are supported for embedded integration applications.

PComm Lite Utility for Easy Management and Software Develoment
CP-104JU's software package includes Moxa's PComm Lite utility, which can be used to diagnose and monitor the status of installed Moxa serial boards. In addition, Pcomm Library, which includes libraries of basic serial I/O and file transfer functions, is included free of charge, giving users a complete and easy-to-use software development tool for Windows applications.
