Safety instructions for all DEWETRON systems
The DEWETRON data acquisition systems may only be installed by experts.
Read your manual before operating the system.
Observe local laws when using the instrument.
Ground the equipment: For Safety Class 1 equipment (equipment having a protective earth terminal),
a non interruptible safety earth ground must be provided from the mains power source to the product
input wiring terminals or supplied power cable.
DO NOT operate the product in an explosive atmosphere or in the presence of ammable gases or
fumes and do not bring the system in contact with water.
DO NOT operate damaged equipment: Whenever it is possible that the safety protection features built
into this product have been impaired, either through physical damage, excessive moisture, or any
other reason, REMOVE POWER and do not use the product until safe operation can be veried by
service-trained personnel. If necessary, return the product to a DEWETRON sales and service ofce
for service and repair to ensure that safety features are maintained.
Keep away from live circuits: Operating personnel must not remove equipment covers or shields.
Procedures involving the removal of covers or shields are for use by service-trained personnel only.
Under certain conditions, dangerous voltages may exist even with the equipment switched off. To
avoid dangerous electrical shock, DO NOT perform procedures involving cover or shield removal
unless you are qualied to do so.
No modications are allowed at the instrument. The fuse in the power module has to be replaced by
the same type. For continued protection against re, replace the line fuse(s) only with fuse(s) of the
same voltage and current rating and type. DO NOT use repaired fuses or short-circuited fuse holder
labels and print on the power module may not be removed.
DO NOT service or adjust alone. Do not attempt internal service or adjustment unless another person,
capable of rendering rst aid and resuscitation, is present.
DO NOT substitute parts or modify equipment: Because of the danger of introducing additional
hazards, do not install substitute parts or perform any unauthorized modication to the product. Return
the product to a DEWETRON sales and service ofce for service and repair to ensure that safety
features are maintained.
Before opening the instrument (experts only) or exchanging the fuse in the power module disconnect
power!
Don’t touch internal wiring!
Don’t use higher supply voltage than specied and take care of the correct polarity, otherwise the
system will be damaged!
Use only original plugs and cables for harnessing.
Safety of the operator and the unit depend on following these rules.
DEWETRON is not responsible for any damage or injury that could result from improper connection or
misuse!

Calibration information
All DEWETRON modules are calibrated at 25 °C and meet their specications when leaving the factory.
The time interval for recalibration depends on environmental conditions. Typically, the calibration should be
checked once a year.
Calibration certicates are available from DEWETRON as an option. DEWETRON offers two types:
ISO traceable DEWETRON certicate
Calibration certicate according to ÖKD (equivalent to DKD)
This manual contains no calibration information. For self calibration, there is a seperate calibration kit
available. The CAL-KIT contains the required cables, software and instructions.

General description
The EPAD2-USB can be used as a standalone device with EPAD2 modules connected to it. The EPAD2-
USB is shipped with an external power supply (100 .. 240 V / 15 VDC) to ensure power supply for up to 16
connected EPAD2 modules.
The EPAD2-USB reads the data from connected EPAD2 modules and provides them via native USB
interface to the PC/Laptop or any other DEWETRON instrument. The independently working EPAD2-USB
module also offers the possibility to create a virtual COM interface in Microsoft Windows®to be used with any
software (e.g. DASYLab).

Installing USB drivers
Before connecting the EPAD2-USB device to your PC/Laptop make sure to install the USB drivers for your
instrument. To install the corresponding drivers insert the DEWETRON Install Media USB drive shipped
with your system and klick <start.exe>. Navigate to "Drivers" > "USB & RS485" > "dewetron_usb".
Execute the <setup.exe> and follow the steps of the installation wizard.
How to setup EPAD2-USB in DASYLab
The EPAD2-USB creates a virtual COM interface in Microsoft®Windows®device manager and can be used
in DASYLab. For this, connect your DEWE2-USB to the PC/Laptop via USB interface after installing the USB
drivers and start DASYLab.
In DASYLab navigate to "DEWETRON module" and click "Serial Port Conguration".

Figure 1: Select "DEWETRON Module" > "Serial Port Conguration"
DASYLab automatically recognizes the used COM port of the driver.
Click "Add" to add the desired COM port.

Proceed with "OK".
Figure 4: Summary of added COM ports used by the driver
Now you have successfully setup your EPAD2-USB in DASYLab.
How to setup EPAD2-USB in DEWESoft™
First of all, a valid DEWESoft™ license is required to run EPAD modules in DEWESoft™ such
as DS-7-LT or higher.
Connect the DEWE2-USB to the PC/Laptop via USB interface after installing the USB drivers and start
DEWESoft™. Due to the fact that DEWESoft™ lists all available COM ports it is neccessary to determine the
correct COM port in the Microsoft® Windows® device manager.
For this, klick on "Start" > "Control panel" and navigate to "Device manager". In the device manager select
"Connectors (COM & LPT)" and note which COM port is used by the driver for the EPAD2-USB.
In DEWESoft™ select "Settings" > "Hardware setup".

Figure 1: "Settings" > "Hardware Setup"
For the EPAD2-USB select "COM port or ofine" from the ampliers dropdown menu. Afterwards select the
"COM port" corresponding to the used one in the Microsoft®Windows®device manager.
