Overview
Industio - Industrial Multiport Async Solutions for PCI
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.
PCI Solution
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”.
Automatic Data Direction Control for RS-485
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.
Termination Resistors Ready for RS-422/RS-485
Termination Resistors are already installed on the Industio CP-114 Series bodards 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”.
