Fluke 2289A Interface
Model: 2289A
Category: Measurement instruments
Group: Interface
                                    The Fluke Helios I Computer Front End is a highly accurate,
easy-to-use data acquisition and control subsystem that can
be used with any kind of personal or mainframe computer.
The Computer Front End is a medium speed, smart intermediary
between a computer and a real world measurement application.
With capacity ranging from a single channel in a minimal
configuration to 1500 channels in a fully expanded system
(1000 channels if the Scan/Alarm option is installed), the
Front End can be adapted to a wide array of applications.
The Front End gathers data and generates control or stimulus
signals through a standard computer interface. It combines a
full range of measurement capabilities and is easy to
program. The Front End’s chassis includes:
o An RS-232-C and an RS-422 standard serial interface port for
communication with a host computer. (Serial printer port
available with Scan/Alarm option.)
o A microcomputer with ROM and RAM to provide local
o Six option slots that accept any of a range of measurement and
control modules. This family of options supports a variety
of both analog and digital inputs and outputs.
Expansion chassis can be added to accommodate more
input/output channels, up to a maximum of 1500 (standard
system) or 1000 (Scan/Alarm option system).
