Notes
• DARWIN is a system comprising a number of data-acquisition equipment components. In the
course of system growth, new models, software and optional features are added to the family to
enhance the systems expandability and flexibility. You can check the versions of your
equipment and software by referring to the style number (Sn) and release number (Rn)
respectively which are shown on the nameplate of the main unit.
When configuring a system, you must confirm that the style number of each component unit and
software meets the following requirement:
the release number of a dedicated software package must be the same or higher than the style
number of the main unit or subunit where the package is installed and where it performs control.
Any equipment/software not meeting these requirements might have incompatible areas with
your system configuration.
In this manual, equipment of style S8 is explained.
For unsupported functions as classified by the style number, see the next page.
• The contents of this manual are subject to change without prior notice as a result of
improvements in the instrument's performance and functions.

Safety Precautions
This instrument is an IEC safety class I instrument (provided with terminal for protective
grounding).
The following general safety precautions must be observed during all phases of operation, service
and repair of this instrument. If this instrument is used in a manner not sepecified in this manual,
the protection provided by this instrument may be impaired. Also, YOKOGAWA Electric
Corporation assumes no liability for the customer’s failure to comply with these requirements.
The following symbols are used on this instrument.
Make sure to comply with the following safety precautions. Noncompliance might result
in injury, death of personnel or damage to the instrument.
WARNING
Power Supply
Ensure the source voltage matches the voltage of the power supply
before turning ON the power.
Power Cord and Plug
To prevent an electric shock or fire, be sure to use the power cord
supplied by YOKOGAWA. The main power plug must be plugged in an
outlet with protective grounding terminal. Do not invalidate protection by
using an extension cord without protective grounding.
Protective Grounding
Make sure to connect the protective grounding to prevent an electric
shock before turning ON the power.
Necessity of Protective Grounding
Never cut off the internal or external protective grounding wire or
disconnect the wiring of protective grounding terminal. Doing so poses a
potential shock hazard.
Defect of Protective Grounding and Fuse
Do not operate the instrument when protective grounding or fuse might be
defective.
Do not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable liquids or
vapors. Operation of any electrical instrument in such an environment
constitutes a safety hazard.
Fuse
To prevent a fire, make sure to use fuses with specified standard(current,
voltage, type). Before replacing the fuse, turn OFF the power and
disconnect the power source. Do not use a different fuse or short-circuit
the fuse holder.
Do not Remove any Covers
There are some areas with high voltages. Do not remove any cover if the
power supply is connected. The cover should be removed by qualified
personnel only.
External Connection
To ground securely, connect the protective grounding before connecting
to measurement or control unit.
Function grounding terminal. This
terminal should not be used as a
“Protective grounding terminal”.

1.1 About DARWIN
What is DARWIN?
Created from a completely new concept that is based on modular architecture, this group of next
generation data acquisition systems is called DARWIN (Data Acquistion and Recording
Windows).
Today many data acquisition networks are increasingly being linked together. More than ever
before, large volume, high speed, accurate, easy-to-use communication functions are essential in
many disciplines.
In the world of measurement and control where the number of measurement points has increased
sharply, the ability to acquire information from a large number of points easily and economically
is crucial. Interfacing to a personal computer allows simplified utilization of the information
while improving quality and efficiency.
DARWIN is based on a unique, new concept to meet these needs. The art of measurement is
revolutionized by DARWIN which integrates functions of conventional recording and data
logging.
Most existing data acquisition equipment has been the all-in-one type in which the measurement
section and display/recording section are contained in one box. While this simplifies operation on
the one hand, it is difficult to adapt to changes in the measurement environment and also makes
expansion difficult.
DARWIN uses a data acquisition engine and remote I/O modules which are completely separate
from each other. It is an entirely new product line which quickly and flexibly copes with various
restrictive conditions and changes in specifications.
Supported by a personal computer, a whole line-up can be created starting with the data
acquisition systems DA series which performs data logging. For example, using a printer as the
output device, the equipment becomes a hybrid recorder (DR series).
Three models are available in the DR series: the DR130, DR230 and DR240. The DR130 is a
portable hybrid recorder, the DR230 is a desk-top hybrid recorder, and the DR240 is a panel-
mount hybrid recorder (component type).
