Overview
Industio—The Industrial Multiport Async Solution
Moxa Industio products are smart, multiport serial I/O solutions for industrial applications. The
CP-134U Series boards, including CP134U-I and CP-134U, 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-point full-duplex (RS-422 or 4-wire RS-485)
or multi-drop 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 multi-drop 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, CP-134U 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-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 PCI BIOS.
This means that the board MUST be plugged into the computer first before installing the driver
software. For more PCI information, refer to the Technical Reference Appendix.
Universal PCI
The 32/64-bit PCI local bus specification specifies both 3.3V and 5V connector types for the PCI
hardware. Moxa’s universal PCI card allows the user to plug into both a 3.3V/5V and 32/64-bit
slot.
Operating System Support
The CP-134U series is compatible with most major industrial platforms, including Windows
2000/XP/2003, Windows NT, Windows 95/98/Me, DOS, and Linux. MOXA device drivers are
provided for smoother installation, configuration, and performance. In this manual, sections for
MOXA Windows 2003, Windows 2000/XP, Windows NT, Windows 95/98, DOS, Linux, and
SCO are included.
