Overview
Industio—The Industrial Multiport Async Solution
Moxa Industio products are smart, multiport serial I/O solutions for industrial applications.
The CP-132U Series boards, including CP-132UL V2, and CP-132UL-I V2 (the
previous version is CP-132U-I V1), are designed for a 32-bit PCI bus with the Plug and
Play and Universal PCI feature. 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. Industio products provide a reliable communication link over a longer
distance (up to 4000 ft), and are suitable for industrial environments. Connections with
point-to-point full-duplex or multidrop half-duplex are available to meet user’s various
needs. Each 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-132UL series board, eliminating
the need for software interference. This means that Windows applications can manage
RS-485 ports, without the need to write extra code for controlling the half-duplex protocol.

With their well-designed and fine-tuned device driver, CP-132UL series boards make full
use of the 128 byte Tx/Rx FIFO and on-chip H/W and S/W flow control, so that they can
transfer data without loss even at speeds as high as 921.6 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 CP-132UL 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, CP132UL
Series boards have built-in surge protection. An optical isolation option (2000V), and surge
protection option (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.
