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 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”.

- Rs 485 cable wiring 41
- For rs 422 485 serial communications when an electrical signal travels through two different resistance junctions in a transmission line the impedance mismatch will sometimes cause signal reflection signal reflection causes signal distortion which in turn will contribute communication errors the solution to this problem is to establish the same impedance at the line ends as in the line itself by terminating them with resistors industio cp 114 series already installs the resistors on board for your convenience indicated as follows the value of the termination resistor should equal the characteristic impedance of the transmission line resistors should be added near the receiving side note stands for termination resistor near the receiving side 42
