Overview

Industio - The Industrial Multiport Async Solution

The term Industio stands for smart multiport serial I/O solution for industrial applications. The Industio

CP-132 Series boards, including CP-132, CP-132I, CP-132S and CP-132IS, are designed for 16-bit

ISA/EISA bus. They offer 2 independent RS-422/RS-485 serial ports for connecting data acquisition equipment

and many other serial devices to the PC and its compatible systems. It offers reliable communication link over

a longer distance (4000ft). It is best suitable for industrial environment. Connections with point-to-point

full-duplex or multidrop half- duplex are available to meet user’s needs. Each port can control up to 32

devices in a multidrop environment.

Automatic Data Direction Control for RS-485

To ease the 2-wire RS-485 half-duplex control, an Automatic Data Direction Control (ADDC) intelligence is built

on each CP-132 board, eliminating the need of software interference. Hence, the Windows applications can

manage the RS-485 port without extra code to control the half-duplex protocol.

With a well-designed and fine-tuned device driver, the Industio CP-132 boards make full use of the 16 byte

Tx/Rx FIFO and on-chip H/W flow control, so that they can transfer data without loss even at high speed such

as 921.6 Kbps. They offer a reliable and high performance solution for serial multiport communications.

Termination Resistors Ready for RS-422/RS-485

Termination Resistors are already installed on the Industio CP-132 boards and no more headaches for finding

proper resistors and connecting them for impedance matching problem. More details are in chapter,

“Connection Cable and Cable Wiring”.

Surge/Isolation Protection

To prevent the boards from damage caused by lighting or high potential voltage, TVSS (Transient Voltage

Surge Suppressor) technology is introduced in some models to protect the board. An optical isolation option

(2000V) and surge protection option (ESD max. 25KV, EFT max. 2KV) is available in this series. This is critical

to harsh environment such as factory.
