World's First Multiport Serial over Fiber Board

Moxa adds a new and innovative serial extension solution, the CP-102UF, the world's first to integrate fiber optic interface on a multiport serial board. The board can be installed directly to the host control PC without buying an additional converter and offers users a more cost-effective extension solution for long distance communication and extra data transmission protection.

The CP-102UF smart Universal PCI boards are designed for industrial automation applications that require a long distance, multi-point, PC-based data acquisition solution. The boards are compatible with all popular operating systems, and each of the 2 serial ports support data rates up to 921.6 Kbps. In addition, the CP-102UF boards work with both 3.3V and 5V PCI buses, allowing them to be installed in virtually any available PC server.

With a maximum data transmission distance of 40 km (with the single-mode model), the CP-102UF cards beat the 15 meter maximum for RS-232, and even the 1.2 km maximum for RS-422/485. For many industrial applications, an even bigger benefit is that optical fiber isolates the data from dangerous increases in ground potential, ground loops, and electrical EMI/RFI electromagnetic radiation.

Ring Operation
With the CP-102UF card, your PC can be included as one node of a fiber ring formed using Moxa's own TCF-142 serial-to-fiber converter. Since each TCF-142 has two fiber ports and one serial port, PCs that are part of the ring will be able to communicate with serial devices connected to the ring. Once the ring has been set up, simply use the DIP switches to configure the CP-102UF to ''Ring mode.'' When one node transmits a signal, the signal travels around the ring until it returns back to the transmitting unit, which then blocks the signals. With the CP-102UF, you can set up fiber rings that are up to 100 km in total length.


  • Extend serial transmission distance up to 40 km
