AC31 AD APTER CARDS
The AC31 adapter card is a general purpose addressable
interface that allows any slave serial device that uses
asynchronous serial communications (terminals, printers,
barcode readers, etc.) to be addressed and attached to a
multidrop network. The host side of the interface is RS485/
422. The slave side of the interface is either RS232 or
RS485/422.

Products
Opto 22 produces a broad array of reliable, flexible hardware and
software
products for industrial automation, remote monitoring, enterprise
data acquisition, and machine-to-machine (M2M) applications.
SNAP Ethernet Systems
Based on the Internet Protocol (IP), SNAP Ethernet systems offer
flexibility in their network connectivity and in the software applications
they work with. The physical network may be a wired Ethernet network, a
cellular wireless network, or a modem. A wide variety of software
applications can exchange data with SNAP Ethernet systems, including:
• Opto 22’s own ioProject™ suite of control and HMI software
• Manufacturing resource planning (MRP), enterprise management,
and other enterprise systems
• Human-machine interfaces (HMIs)
• Databases
• Email systems
• OPC client software
• Custom applications
• Modbus/TCP software and hardware.
SNAP Ethernet system hardware consists of controllers and I/O units.
Controllers provide central control and data distribution. I/O units provide
local connection to sensors and equipment.
SNAP OEM Systems
Opto 22 SNAP OEM I/O systems are highly configurable, programmable
processors intended for OEMs, IT professionals, and others who need to
use custom software with Opto 22 SNAP I/O modules.
Linux® applications running on these systems
can read and write to analog, simple digital, and serial
I/O points on SNAP I/O modules using easily
implemented file-based operations. Applications can
be developed using several common development
tools and environments, including C or C++, Java,
and shell scripts.
M2M Systems
Machine-to-machine (M2M) systems connect your business computer
systems to the machines, devices, and environments you want to monitor,
control, or collect data from. M2M systems often use wireless cellular
communications to link remote facilities to central systems over the Internet,
or to provide monitoring and control capability via a cellular phone.
Opto 22’s Nvio™ systems include everything you need for M2M—
interface and communications hardware, data service plan, and
Web portal—in one easy-to-use package. Visit nvio.opto22.com for
more information.

COMPANY INFORMATION
Opto 22 Software
Opto 22’s ioProject and FactoryFloor® software
suites provide full-featured and cost-effective
control, HMI, and OPC software to power your
Opto 22 hardware. These software applications
help you develop control automation solutions, build
easy-to-use operator interfaces, and expand your
manufacturing systems’ connectivity.
Quality
In delivering hardware and software solutions for worldwide device
management and control, Opto 22 retains the highest commitment to
quality. We do no statistical testing; each product is made in the U.S.A.
and is tested twice before leaving our 160,000 square-foot manufacturing
facility in Temecula, California. That’s why we can guarantee solid-state
relays and optically-isolated I/O modules
for life
.

Opto 22’s Product Support Group offers comprehensive technical
support for Opto 22 products. The staff of support engineers represents
years of training and experience, and can assist with a variety of project
