1 Introduction
Before you start assembling the 1 Wire Bus Coupler Ethernet and before you take the device into operation,
please read these assembly and operating instructions carefully to the end, especially the section referring to the
safety notes.
2 Product description
The 1-Wire Bus Coupler Ethernet enables a stable and electrically isolated connection of the 1-Wire network to a
PC or minicomputer (e.g. Raspberry Pi). Ground loops or fault transmissions between 1-Wire network and
computer are prevented by the use of the 1-Wire bus coupler Ethernet.
Within the 1-Wire Bus Coupler, the serial to 1-Wire module DS2480 from Dallas / Maxim is used. This module - in
combination with the complex internal power supply and the Ethernet module - are the basis for a very stable 1-
Wire network.
The 1-wire master within the 1-wire bus coupler Ethernet (DS2480 module) supports the "Strong Pull Up" function
and is therefore particularly suitable for the operation of large 1-wire networks.
To configure the Ethernet interface, a suitable program "Config Tool" is available via the article download. The
"Config Tool" is part of the "Software package", which you will find in the article Download.
On computer side, the 1-Wire bus coupler is connected via a "Virtual Serial Port" (VSP). The "VSP_INSTALLER"
tool is available for configuring the VSP. Both programs are available for download in our webshop.
On software side, a serial interface (COM port) is available for integration into your application after installation of
the VSP.
An external power supply is required to operate the 1-wire Bus Coupler Ethernet module. The outputs of the
module (5V and 1-wire bus) are short-circuit-proof and galvanically connected to the supply voltage input. For
details on the connection, please refer to the “connection plan".
The 1-Wire Bus Coupler has LED displays for "Power" and "1-Wire activity", "Ethernet Link" and "Traffic".

Windows:
For Windows, a bus coupler configuration program (Config-Tool) and a software for the creation of a virtual serial
port (VSP-Tool) are available.
Linux:
At the moment we have no available configuration software, respectively connection for Linux.
We would like to refer to the „remserial“ project: http://lpccomp.bc.ca/remserial/.
7 Update Ethernet interface (Firmware for interface)
No firmware update of the Ethernet interface should be necessary during the entire lifetime.
If you do, please use the "Config Tool 1" of the software package.
Before starting the update, close all applications and services that could write or read data to the bus coupler!
Malfunctions of the 1-Wire bus coupler due to programming or an update are not subject to the warranty
conditions.
Should an update nevertheless be necessary, we will be pleased to carry out an update for you as a service. We
are also happy to carry out the programming of the network interface for you. In this case, please return the
device back to us for further handling.

9 Operating conditions
The operation of the assembly group can take place only on condition of observing the required voltage and the
ambient conditions. The operating position of the device is irrelevant. The device is meant to be used in dry and
dust-free areas.
Should condensed water build up, an acclimatization period of at least 2 hours must pass.
Assembly groups and components do not belong into the hands of children!
The building group can be operated only under the supervision of an electrically skilled person.
In industrial facilities, the accident prevention regulations of the federation of industrial professional associations
for electrical installations and equipments must be observed.
Do not operate the assembly group in an environment with inflammable gases, vapours or dusts or in an
environment where such gases, vapours or dusts may be found.

12 Safety instructions
When using products that come into contact with electrical voltage, the valid VDE regulations must be observed, especially
VDE 0100, VDE 0550/0551, VDE 0700, VDE 0711 and VDE 0860
•All final or wiring work must be carried out with the power turned off.
•Before opening the device, always unplug or make sure that the unit is disconnected from the mains.
•Components, modules or devices may only be put into service if they are mounted in a contact proof housing.
During installation they must not have power applied.
•Tools may only be used on devices, components or assemblies when it is certain that the devices are
disconnected from the power supply and electrical charges stored in the components inside the device have been
discharged.
•Live cables or wires to which the device or an assembly is connected, must always be tested for insulation faults
or breaks.
•If an error is detected in the supply line, the device must be immediately taken out of operation until the faulty
cable has been replaced.
•When using components or modules it is absolutely necessary to comply with the requirements set out in the
accompanying description specifications for electrical quantities.
•If the available description is not clear to the non-commercial end-user what the applicable electrical
characteristics for a part or assembly are, how to connect an external circuit, which external components or
additional devices can be connected or which values these external components may have, a qualified electrician
must be consulted.
•It must be examined generally before the commissioning of a device, whether this device or module is basically
suitable for the application in which it is to be used.
•In case of doubt, consultation with experts or the manufacturer of the components used is absolutely necessary.
•For operational and connection errors outside of our control, we assume no liability of any kind for any resulting
damage.
•Kits should be returned without their housing when not functional with an exact error description and the
accompanying instructions. Without an error description it is not possible to repair. For time-consuming assembly
or disassembly of cases charges will be invoiced.
•During installation and handling of components which later have mains potential on their parts, the relevant VDE
regulations must be observed.
•Devices that are to be operated at a voltage greater than 35 VDC / 12mA, may only be connected by a qualified
electrician and put into operation.
•Commissioning may only be realized if the circuit is built into a contact proof housing.
•If measurements with an open housing are unavoidable, for safety reasons an isolating transformer must be
installed upstream or a suitable power supply can be used.
•After installing the required tests according to BGV A3 / Betriebssicherheitsverordnung must be performed.
