2. Getting started
This chapter will help you to install the software, connect your IOLITE® system to the PC via EtherCAT®
and will show you how to configure DEWESoft®.
To follow these steps, you need the following items:
●your brand new IOLITE® system (included in the shipment)
●your IOLITE® EtherCAT® cable (included in the shipment)
●your PC with Windows 10 (older versions like Windows® 7 may also work)
2.1. Software installation
For optimal working, we recommend that you install the latest version of Dewesoft®. If you already have
installed older version Dewesoft® it is recommended that you find the newest version on the website.
The details of software installation can be found on https://download.dewesoft.com.
2.2. Connecting IOLITE®
In this chapter, you can see the basic instructions for connecting IOLITE® devices. Advanced
connections are described in the following chapters.
IOLITEr
First connect the power supply cable (PS-120-L1B2f) to the PWR IN LEMO 1B 2-pin connector. Then
connect standard ethernet cable to IN connector of BUS 1 on IOLITE-GATE. Finally connect the other
side of the ethernet cable to the LAN port of PC. You can find advanced connections in chapter 3.3.1.4.

IOLITEs
First connect the power supply cable (PS-120-L1B2f) to the PWR IN LEMO 1B 2-pin connector. Then
connect L1T8f-RJ45-1M cable (LEMO side) to IN connector of BUS 1 on IOLITEs back panel. Finally
connect the other side of the L1T8f-RJ45-1M cable (RJ45 side) to the LAN port of PC. You can find

2.2.2. Channel Setup IOLITE®
In the channel setup you can see a preview of the connected devices on the left side.
When you click on a connector in the image the corresponding channel in the Channel setup
grid will automatically be selected. This also works the other way around: when you select a
channel (or multiple channels) in the setup grid, the corresponding connectors in the image
will be highlighted.
The sampling rate will be set for all connected IOLITE® slices: of course only up to the max. sampling
rate of the individual slices.

2.3. Simple Measurement
This chapter describes measurement basics, how to configure IOLITE® and gives some details on the
measurement setup.
2.3.1. Help - Manual
Note that this document is just a quick start guide. For detailed information about DEWESoft® consult
the Manual. To open the manual press the F1 button or click on the Options button and then select
Manual from the pop-up menu.
Illustration 7: Help - Manual
When DEWESoft® has started up, you will be in the Measure mode and see the Setup files list. Click on
Ch. setup (on the right of Setup files) to switch to the Channel setup mode.

2.3.2. Analogue channel setup
In the analogue channel setup screen you can see all channels of your connected IOLITE® systems. Per
default only the first channel will be set to Used. Unused channels will not show up in measure mode
and can thus not be used for display, calculations or storing: thus, we will also set the other channels to
the used. You can left-click on the Used column of channel 2 (1), hold the mouse button and move the
mouse down to channel 8 (2): then release the mouse button and all channels will be selected – this is
shown by the black rectangle around the buttons. Then you can click into the selected region to toggle
Used/Unused for all channels at once. The selected channels will also be highlighted in the small
preview image of the device (3).
When you press the Setup button of a channel (the column at the right edge of the channel table – not
shown in this screen-shot), you can change all the settings of the channel amplifier.
You can also change the sample rate of the IOLITE® (4).

2.3.3. Sample rate
One of the most important settings is the sample rate. The sample rate defines how many data points,
IOLITE® will transfer to DEWESoft®. Higher sample rate also means that more data needs to be
transferred via EtherCAT® to your computer.
The sampling speed mainly depends on your application. To display your signal in time domain with a
good time resolution, you should sample 10 to 20 times faster than the frequency of the signal that you
want to measure, e.g. 1 kS/s for a 50 Hz sine-wave. If you have a lot of high frequency components, it
may be necessary to sample 100 times faster, e.g. 5 kS/s for the 50 Hz sine-wave, or even more. If you
display only the frequency domain (FFT analysis), a 2.5 times faster sampling would be sufficient (125 S/s
for the 50 Hz sine-wave). The higher the sampling rate, the better the time resolution. But also the file
size will increase.

2.3.4. Measurement Mode
A click on Measure (at the right side of Ch. setup in Illustration 11) will take you to the Recorder screen
measure mode where you can already see live data.
Hint
When switching to Measure mode the data will not be stored automatically.
Illustration 11: Measure mode
In measure mode you can have several measurement screens (5). DEWESoft® will create 2 default
screens: Recorder and Custom but you can also create new screens or change the visual displays of the
existing screens as you like.
The most important sections of the Measure mode are highlighted in screen-shot Illustration 10:
(1) shows the live measurement data in different measurement instruments which are depending on
the selected measurement screen. In this case we see a recorder instrument which displays all your

measurement channels. You can use the channel-selector list (2) to assign measurement channels to
the instruments. Each instrument has different settings. (3) shows the settings of the currently selected
recorder instrument.
To start storing the data to a file, press the Store button (4). When you are done, press the Stop button
to stop recording.
Now DEWESoft® has created a datafile with all the data that you have seen during the recording
session. You can now click the Analysis button (on the left-top of the screen to the right of the Measure
button) to go to Analysis mode.
2.3.5. Analyse Mode
When you have just stopped a measurement, DEWESoft® will automatically open the last recorded
data file in Review mode, so that you can start the analysis right away.
Illustration 12: Analyse mode
The Review mode is much like the measurement mode. You will see the same measurement screens,
the channel-selector list and the properties of the currently selected instrument.
Differences are:
(1) you have additional tool-buttons
(2) there is a Signal overview window which will show you the whole data of one selected channel of the
data file
Now you can use the cursors to analyse your data, zoom in and out of the data, click Offline math to add
computations based on your data, etc. You can also change the design of your measurement screens,
print reports based on your data and export the data to other file formats for further analysis.

2.4. Advanced configuration
Note, that the DEWESoft® launcher has already done the hardware setup for you – you can check this in
the Settings dialogue. Click the Settings button (1) – and then click the Settings Menu item (2).
Illustration 13: Open settings dialogue
In the Analog tab sheet, DEWESoft USB must be selected in order to user you IOLITE® device (see (1) in
the image). All IOLITE® devices will be shown in the device list (2).
If you add a device while this screen is open (or if your device is not shown yet), you can press the
Refresh button (3) to scan for devices. When you select a device from the list you will see all the device
details and settings in the right area (4).

2.5. Licensing
As soon as you activate your IOLITE® system in the hardware setup, DEWESoft® will be licensed and
you are ready to go (the license information is stored in the IOLITE® device). No need for any online or
offline licensing!
Note, that all licenses regarding IOLITE® will only work when the IOLITE® system is connected to your
PC and the device has been activated in the hardware setup.
2.6. Troubleshooting
If your IOLITE® device is not found by DEWESoft®:
●If you did not restart Windows after the software installation, restart now
●Make sure that you have started DEWESoft® version X3 SP8 or higher
●Make sure that the external power supply is connected and okay
●Disconnect the EtherCAT® cable and reconnect it. If this does not work, try to connect the
EtherCAT® cable to another Ethernet port of your PC
●Try to restart DEWESoft®
●Try to restart the PC
