Introduction
This manual contains information designed to
familiarize you with the features and functions of
the following serial port data recording modules:
DI-151RS
DI-195B
and also with WINDAQ/Lite waveform recording
software and WINDAQ Waveform Browser playback
and analysis software.
DI-151RS
The DI-151RS is a portable, two-channel data
recording module that communicates through your
computer’s RS-232 (or serial) port. It can record
data at rates up to 240 samples per second with 12-
bits of measurement accuracy.
The DI-151RS is powered directly from the
computer to which it is connected (through the RS-
232 cable).
The DI-151RS is equipped with a dedicated
thermistor input, two digital inputs, and two single-
ended, bipolar analog input channels.
DI-195B
The DI-195B is a two-channel data recording
module that communicates through your computer’s
RS-232 (or serial) port. It can record data at rates up
to 240 samples per second with 12-bits of
measurement accuracy.
The DI-195B is powered by the included wall outlet-
type adapter, which can be plugged into any single-
phase, 120 volt, 60 Hz. AC source. It features two,
signal-conditioned, differential, bipolar analog
inputs (screw terminal access, maximum
measurement range is defined by the DI-5B
modules). The DI-195B allows you to plug any two
DI-5B signal conditioning modules into its
backplane. The DI-5B signal conditioning modules
then filter, isolate, amplify, and/or convert virtually
any industrial signal that is applied into a high level
analog voltage, perfectly suited for recording.
WINDAQ/Lite Waveform Recording Software and
WINDAQ Waveform Browser Playback and
Analysis Software
The WINDAQ software shipped with all of the serial
port instruments consists of WINDAQ/Lite waveform
recording software and WINDAQ Waveform Browser
playback and analysis software.
WINDAQ/Lite waveform recording software can be
used with any Dataq Instruments hardware product.
It allows you to record waveforms directly and
continuously to disk while monitoring a real time
display of the waveforms on your computer screen.
It operates at the full sample rate of the instrument
being used (allowing you to see a real time display
of your waveform signals on your computer’s
monitor at the instruments full sample rate), but is
limited to 240 Hz maximum throughput when you
enter the record mode.
WINDAQ Waveform Browser allows you to review,
measure, analyze, compress, cut-and-paste,
export/import, and otherwise manipulate the
recorded waveform information. It is available for
download free-of-charge from our web site
(www.dataq.com).
Conventions Used in the Documentation
Before you start using the DI-151RS, DI-195B,
WINDAQ/Lite, or WINDAQ Waveform Browser
software, it’s important to understand the terms and
notational conventions used in this documentation.
General Conventions
Commands you choose are given with the menu
name preceding the command name. For example,
the phrase “Choose File Open” tells you to choose
the Open command from the File menu. This
naming convention describes the sequence you
follow in choosing a command — first you select
the menu, then you choose the command.
Mouse Conventions
In general, most mouse actions require only the left
mouse button. For example, carrying out a menu
command or working in a dialog box requires only
the left mouse button. However, the right mouse
button is not totally neglected. Among other things,
the right mouse button is used for copying waveform
data to the clipboard, waveform scaling, selecting a
waveform channel, etc.
Since the majority of mouse procedures are done
with the left mouse button, we will not specify
which mouse button to click, drag, or double-click
with in the procedures unless it is the RIGHT
mouse button. When the right mouse button is
required, it will be specified as such. For example,
“Double-click the right mouse button anywhere in
the bottom annotation line to move the cursor to the
