Industio - Industrial Multiport Async Solutions for PCI

PCI Solution

Automatic Data Direction Control for RS-485

Termination Resistors Ready for RS-422/RS-485

1 Introduction

The term Industio stands for smart multiport serial I/O solution for industrial applications. The Industio CP-114 Series boards, including CP-114, CP-114I, CP-114S and CP-114IS, are RS-232/RS-422/RS-485 4-port serial communication interface boards for 32-bit PCI bus with “Plug and Play” feature. The Industio CP-114 Series support all three serial interfaces, RS-232, RS-422 and RS-485, in one board. Two of the four ports are RS-422/485 ports and the other two ports can be configured to RS-232 or RS-422/485 individually. Each RS-422/RS-485 port can control up to 32 devices in a multidrop environment. With this versatile design, it can control different kinds of serial device, such as modems, CNC and other industrial machines, without the need to use interface converters.

The board complies with PCI Spec. 2.1 and has neither switch nor jumper. The BIOS automatically assigns the hardware configuration for the IRQ number and memory addresses. Hence, the board MUST be plugged first before installing the software driver. For more PCI information, please refer to the Appendix, “Technical Reference”.

To ease the 2-wire RS-485 half-duplex control, Automatic Data Direction Control intelligence is built on Industio CP-114 Series board. Eliminating the need of software interference. Hence, the 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-114 boards make full use of the 32 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, bps. The offer a reliable and high performance solution for serial multiport communications.
