X300 Bus Enumerator

The CP-132 Series of 2-port serial boards is designed for RS-422/485 industrial communication. CP-132 serial boards support 2 independent RS-422 or RS-485 ports, with each port able to control up to 32 devices in a multidrop environment. This series of PCI 2-port serial boards provides a reliable communication link (RS-422/485) over a longer distance (up to 4000 ft), and is suitable for industrial environments.

By using ADDC(Automatic Data Direction Control) intelligence, applications can easily manage half-duplex RS-485 ports data transmission and receiving without the need for writing extra code. In addition, on-chip hardware flow control and built-in termination resistors guarantee data integrity, and optical isolation and surge protection options are also available to deliver high reliability. All of the above attributes make the CP-132 Series of multiport serial boards suitable for harsh industrial applications.
