2-port RS-422/485 Universal PCI serial boards with optional 2 kV isolation

Moxa’s CP-112UL/UL-I series of multiport serial boards- PCIe RS485 Card which is designed to be used by industrial automation system integrator f

or long distance, multi-point, PC-based data acquisition applications. On-chip Automatic Data Direction Control for precision RS-485 communication requires precise timing control for enabling and disabling the line driver. Moxa’s Turbo Serial EngineTM chip that powers the CP-112UL/UL-I boards comes with on-chip ADDC®, which makes RS-485 as easy to use as RS-232. The PCIe RS485 Card comes with 2 RS-422/485 serial ports, both of which can achieve data rates up to 921.6 kbps. 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 protection is available to prevent equipment damage.
