The smart Multiport Serial Boards are designed to be used by industrial automation system integrators for long distance, multi-point PC-based data acquisition applications.


The Serial Boards provide 2, 4 or 8 RS-232/422/485 serial ports, each capable of data rates up to 921.6 Kbps. 


In RS-485 mode, the serial port can connect up to 31 daisy-chained RS-485 devices within a range of 1.2 km. For long distance RS-485 communication, optional 2 KV optical isolation protection is available to prevent equipment damage.
