1 Product description
The Repeater is used to amplify or regenerate data signals in 1-Wire Networks.
By using the Repeater, a 1-Wire Network can be extended and a significant increase in network stability can
be achieved. Particularly recommended for networks with a "star structure".
The Repeater is simply connected to a 1-Wire cable. No software is necessary.
It supports all types of 1-Wire Masters, such as USB Adapters, 1-Wire Bus couplers, 1-Wire Controllers or
solutions with microcontrollers with 5 V signal level.
No additional power supply or configuration is necessary for the Repeater.
The Repeater is simply connected into the data, ground and 5 V supply line of an existing 1-Wire Network.
One Repeater can be used per bus line. Several Repeaters can be operated in parallel or in series.
The Repeater V2 can be installed at any point within a 1-Wire Bus section.
When operating 1-Wire Networks with many bus participants, long cables or a star-shaped structure, the
signal quality quickly deteriorates significantly, leading to communication problems. The main reason for this is
the high capacitive bus load caused by the cabling, connectors and 1-Wire modules / components.
By using the 1-Wire Repeater, the Bus load for the Bus master (e.g. USB adapter or 1-Wire Bus coupler) is
significantly reduced.

6 Bus extension
The 1-Wire Repeater achieves the highest effect when it is installed in the first 1/4 - 1/3 of a data line. If a
1-Wire network consists of several 1-Wire lines, e.g. one line to the basement and another to the ground floor
of a house, a 1-Wire Repeater can be provided for each 1-Wire line.
6.1 Example Bus extension
In order to be able to bridge a long distance, it is possible to connect several 1-Wire Repeaters in series.
It has been shown in practice that positioning the first repeater after approx. 1/4 - 1/3 and another one after
approx. 2/3 to 3/4 of the cable distance is very effective. A transmission test before final positioning is
recommended.
Note
The module may only be operated at the voltages and under the ambient conditions specified for it. The unit
may be operated in any position.
The modules may only be put into operation by a qualified electrician.
For further information on the operating conditions, see the following instructions under
"Operating conditions".

7 Parallel operation of Bus sections
Several Repeaters can be operated in parallel to reduce the cable distance acting on the Bus master. In
practice, the use of one 1-Wire Repeater per Bus segment has proven to be recommendable.

8 Function of the Repeater
The following diagram shows the function of the 1-Wire Repeater.

Input signal, curve 1 (yellow):
If the 1-Wire signal shape deforms too much (curve 1, yellow) due to long cables, many sensors and
connectors (combined as Bus load), the data timing may no longer be maintained. A deteriorating
transmission of the 1-Wire signal is clearly visible. The falling and rising edges no longer have a rectangular
signal shape. In these cases, communication problems with individual sensors may occur. The errors
sometimes only occur sporadically. In the measured 1-Wire test environment, transmission problems occurred
at times without a repeater.

required 1-Wire timing.

The module does not require any software.
11 1-Wire Network, Cabling in general
The special feature of the 1-Wire system is the "BUS technology". All devices (sensors and actuators) are
operated in parallel on a three-wire line, which is used for both power supply and data communication. The
1-Wire Bus system joins the list of other successful Bus systems such as CAN or Modbus RTU. All of the
installation principles recommended for these are also applicable and apppropriate to 1-Wire.
The maximum size of a 1-Wire Network is determined by various factors. These are mainly:
- Total cable length and cable type
- Number of 1-Wire devices
- Type of cable installation (topology)
- Number and design of the cable connectors (unnecessary connection transitions should be avoided).
All factors in total are summarised and designated as 1-Wire Bus load. Each increase in a factor increases the
total 1-Wire Bus load for the 1-Wire Controller and thus reduces the maximum network size.
Based on our many years of experience and a lot of feedback from customers, the following conservative
recommendation can be made:
- Maximum cable length 50 -120m
- Number of 1-Wire devices no more than 20 -22 pieces
- As linear a topology as possible without T-junctions
The topology in particular plays a major role. If possible, linear topology should be used. The linear topology can
be compared like pearls on a pearl necklace. The data line should be laid from one device to the next without
T-joints.
Furthermore, the type of cable used can also be mentioned here. We recommend for the cabling
CAT5 or CAT6 network cable. It is also possible to use J-Y(St)Y telephone cables and KNX cables. Longer cable
runs are possible with CAT5 versus CAT7 cables.
With twisted pair cables, a longer connection length can be achieved in an undisturbed environment, as the
capacitive bus load is lower. A total length of 50 m and more can be easily achieved without additional measures.
In disturbed, commercial and industrial environments, the cable should always be shielded to increase the
"robustness" or interference sensitivity of the system.
Note
The above statements on 1-Wire are hints and tips and do not describe any product property or represent
any guaranteed product property of the device and the 1-Wire Controllers.

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
