4-port RS-232/422/485 low-profile Universal PCI serial board with optical isolation, 0 to 55°C operating temperature (includes DB9 male cable)

Moxa’s CP-114UL/UL-I Series of multiport serial boards is designed to be used by industrial automation system integrators for long-distance, multipoint, PC-based data acquisition applications. On-chip Automatic Data Direction Control for precision RS-485 communication requires precise timing control to enable and disable the line driver. The Moxa Turbo Serial Engine™ chip that powers the CP-114UL/UL-I boards come with on-chip ADDC®, which makes RS-485 as easy to use as RS-232. In RS-485 mode, the serial port can connect up to 31 daisy-chained RS-485 devices within a range of 1.2 km. For long-distance RS-485 communication, 2 kV electrical isolation protections are available to prevent equipment damage.
