The CP-132UL Series by Moxa is a high-performance, 2-port Universal PCI serial board supporting RS-422/485 interfaces, specifically engineered for industrial automation and long-distance communication. Designed for multipoint, PC-based data acquisition, the board offers baudrates up to 921.6 kbps and enables transmission up to 1.2 km with RS-485, supporting up to 31 devices in a daisy-chain setup.

A standout feature is the integrated ADDC® (Automatic Data Direction Control), simplifying RS-485 to function like RS-232 with automatic line control. For environments demanding higher electrical resilience, the CP-132UL-I variant offers 2 kV isolation. Its compact MD1 low-profile design fits into smaller PCs without compromise.

Full driver support for Windows, Linux, and UNIX platforms ensures seamless system integration, while built-in Tx/Rx LEDs provide ease of monitoring and maintenance.
