1 Introduction
Before you start assembling the 1 Wire Bus Coupler USB
V3 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 Serial Bus Coupler USB V3 establishes a stable, electrically isolated connection among a 1-Wire
network and a computer. Special feature of the 1-Wire Bus Coupler USB V3 is an external voltage supply. Thus,
operating safety of the data connection to a computer will significantly be enhanced. Issues caused by unreliable
USB voltage supplies will be avoided. The use of more expensive USB hubs is no longer necessary.
The 1-Wire output of the bus coupler is isolated among the USB data supply and the voltage supply. Thus,
ground loops or EMC emissions and grounding issues from a computer to the 1 Wire network are efficiently
prevented. The isolation significantly reduces stray radiations ("electric smog") in living areas and enhances
electric safety among the systems. For galvanic isolation state-of-the-art high-speed optocouplers and special
isolated power adapters are being used. Even the 1-Wire „data“ LED is isolated controlled by optical coupler
The 1-Wire component DS2480 from Dallas/Maxim is used within the 1-Wire Bus Coupler. This component,
combined with the complex internal voltage supply, is the basis for a very stable 1-Wire network. The DS2480
component supports the „Strong Pull Up“ function and is thus predestined for the use in large 1 Wire networks as
well.
For the voltage supply, the 1-Wire Bus Coupler has a wide-range input of 9-32VDC and is thus equally suitable
for 12V systems and typically industrial 24VDC supplies. You can find compatible top-hat rail power adapters or
socket power adapters in our webshop.
Individual 1-Wire sensors can be connected directly. For major 1-Wire networks it is recommended to use a
1-Wire Hub III.
Please refer to the connection plan for further details in regards to the electric connection.

9 Software
We recommend the use of the latest FTDI- and TEMX driver. We do not recommend the use of any driver that
has beta status. Once the FTDI driver is installed, the 1-Wire Bus Coupler with USB interface is available as
software-based serial bus coupler. The 1 Wire Bus Coupler USB can be operated with any software, that is
aligned to operate the COM Port adapter „DS9097“.
The 1-Wire Bus Coupler is being operated with 9600 Baud and settings of 8 data bits, no parity and 1 stop bit. As
1-Wire interface for the 1-Wire Bus Coupler a Maxim Chip DS2480 is used.
The 1-Wire Bus Coupler was tested with the following software:
IP-Symcon, 1-Wire Viewer (Windows), FHEM
Note: The „Strong Pullup“ function must be activated.
10 USB-Connection cable
Please note, that the cable length is limited to 5 m in maximum for the USB data cable among the 1-Wire Bus
Coupler and the PC interface. To bridge USB cable sections of 30 to 50 meters, USB long distance extension
cables are offered in our webshop. These long distance extension cables use a CAT5, CAT6 or CAT7 network
cable for data transfer. This network cable cannot be connected with a TCP/IP network or a hub/switch network.
11 Windows power management for USB ports
As soon as the Virtual Com Port Driver is installed, the 1-Wire Bus Coupler USB may break down after several
hours of operation. This may be caused by the Windows Power Management settings for USB ports. The
energy saving mode is activated in Windows basic settings. To operate the 1-Wire Bus Coupler USB, these
settings must be deactivated.
In Windows7, WHS and Server 2008, the drivers are to be installed with admin rights.
Windows 7 Energy Options You will find the Windows 7 energy options under:
Start / Control Panel / Energy Options
Windows 7 offers two options: Balanced and Energy saving
mode. The recommended mode is Balanced where it
focusses on PC performance (not energy saving). Under
Advanced Settings, you have several setup options.
USB, Setup for selective operation:
Uncheck the box. The port will then be permanently
enabled.
In addition we recommend the use of the „Presenter View“as
the computer will operate with no screensavers. Further
information can be found at:

12 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
areas free of dust.
Should condensed water build up within the sensor, an acclimatization period of at least 2 hours must be met.
The components can be operated only under the supervision of an electrically skilled person. Assembly groups
and components do not belong into the hands of children.
In industrial facilities, the accident prevention regulations of the federation of industrial professional associations
for electrical installations and equipment must be observed.
Do not operate the components in an environment with inflammable gases, vapors or dusts or in an environment
where such gases, vapors or dusts may occur.
13 Assembly
The mounting place must be protected against moisture. The module may only be used in dry indoor rooms or in
protected outside areas. The device is designed for fixed installation within a switching cabinet.
14 Disposal Note
Do not dispose of this device in the household waste. Electronic devices must be disposed
in accordance with directives for disposing of waste electrical and electronic equipment at
local collection points for electronic waste material.
15 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.
