Overview

Industio—The Industrial Multiport Async Solution

Moxa Industio products are smart, multiport serial I/O solutions for industrial applications. The Industio CP-134U Series boards, including CP134-UIand CP-134UL, are designed for a 32-bit PCI bus with the Plug and Play and Universal PCI feature. The ports for these boards can be configured independently, with ports 1 and 2 set to the RS-232, RS-422, or RS-485 interface, and ports 3 and 4 set to the RS-422 or RS-485 interface. Industio products provide a reliable communication link over a longer distance (up to 4000 ft for ports set to the RS-422/485 interface), and are suitable for industrial environments. Connections with point-to-pointfull-duplex(RS-422 or 4-wire RS-485)or multidrop half-duplex(2-wire RS-485) are available to meet user’s various needs. And each RS-485 port can control up to 32 devices in a multidrop environment.

ADDC™ (Automatic Data Direction Control) for RS-485

To make it easier to manage 2-wire RS-485 half-duplex connections, ADDC™ (Automatic Data Direction Control) intelligence is built into each CP-134U series board, eliminating the need for software interference. This means that Windows applications can manage RS-485 ports without needing to write extra code for controlling the half-duplex protocol.

With their well-designed and fine-tuned device driver, Industio CP-134U boards make full use of the 64 byte Tx/Rx FIFO and on-chip H/W flow control, so that they can transfer data without loss even at speeds as high as 230.4 Kbps, providing a reliable, high performance solution for serial multiport communications.

Termination Resistors Ready for RS-422/485

Termination Resistors are already installed on the Industio CP-134U series boards, eliminating the headaches involved in determining the proper impedance for the resistors. For more details, refer to the “Connection Cable and Cable Wiring” chapter.

Surge/Isolation Protection

To prevent boards from being damaged by lightning or high potential voltage, TVSS (Transient Voltage Surge Suppressor) technology is included in some models to protect the board. An optical isolation option (2000V), and embedded surge protection (max. ESD of 16 KV, max. EFT of 2 KV) are also available in this series. Both of these features provide protection when the boards are used in critical or harsh factory-type environments.

PCI Solution

The board complies with PCI Spec. 2.1 and does not require either switches or jumpers. The hardware configuration for the IRQ and I/O address is automatically assigned by the
