* PComm Lite utility for easy management and software development

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

Moxa 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.
