CP-134U V2

4-port RS-422/485 Universal PCI w/ 2 KV Isolation Protection

The CP-134U V2 Series of Smart Multiport Serial Boards is used by Industrial Automation system integrators for designing long distance, multi-point PC-based data acquisition applications.

On-chip Automatic Data Direction Control for Precision RS-485 Communication
RS-485 communication requires precise timing control to enable and disable the line driver. Powered by Moxa's Turbo Serial Engine™ chip that comes with on-chip ADDC™ (Automatic Data Direction Control), sending RS-485 packets over CP-134U V2 is as easy as using RS-232.

RS-485 multidrop for up to 31 devices within 1.2 km
The CP-134U V2 Universal PCI Multiport Serial Board has 4 RS-422/485 serial ports, each capable of data rates up to 921.6 Kbps. In RS-485 mode, the serial port can connect up to 31 daisychained RS-485 devices within a range of 1.2 km. For long distance RS-485 communication, optional 2 KV isolation protection is available (CP-134U-I V2) to prevent equipment damage.
