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.

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".
