Introduction
The CP-132UL and CP-132UL-I are 2-port Universal PCI boards designed for industrial automation applications that require a long-distance,
multipoint, PC-based data acquisition solution.
On-Chip Automatic Data Direction Control for Precise RS-485 Communication
RS-485 communication requires precise timing control to enable and disable the line driver. Our Turbo Serial Engine™ chip that powers the CP-
132UL/UL-I boards comes with on-chip ADDC®, which makes RS-485 as easy to use as RS-232.
RS-485 Multidrop for up to 31 Devices Within 1.2 km
The CP-132UL/UL-I Universal PCI boards have two RS-422/485 serial ports, both of which can achieve data rates of up to 921.6 kbps. In RS-485
mode, the boards can connect up to 31 daisy-chained RS-485 devices within a range of 1.2 km. For long-distance RS-485 communication, choose
the CP-132UL-I model, which comes with 2 kV electrical isolation protection to prevent equipment damage.
Top Serial Performance
With over 30 years of experience in serial board design, we have perfected the design of our high-performance serial data transmission chip. The
Turbo Serial Engine™ chip provides serial boards with a 128-byte FIFO, on-chip software flow control, and burst data mode. Thanks to the Turbo
Serial Engine™, we are able to offer smart serial boards with exceptional performance.
Drivers Provided for Windows, Linux, and UNIX
We continue to support a wide variety of operating systems, and the CP-132UL/UL-I boards are no exception. Reliable Windows, Linux, and UNIX
drivers are provided for all of Moxa's boards, and other operating systems, such as WEPOS, are also supported for embedded integration.
