The CP-134U and CP-134U-I 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 is as easy as using RS-232.

RS-485 multidrop for up to 31 devices within 1.2 km 
The CP-134U 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) to prevent equipment damage.

• Over 700 Kbps data throughput, for top performance
• 4-port RS-422/485 interface with ADDC™ and up to 921.6 Kbps
• 2-wire/4-wire RS-485 communication up to 1.2 km
• Built-in 15 KV ESD and optional 2 KV optical isolation protection
• 128-byte FIFO and on-chip H/W, S/W flow control
• Universal PCI compatible with 3.3/5V PCI and PCI-X
• Windows 2003/XP/2000/98/ME, Linux, Unix driver support
