1-Wire Bus Coupler USB Pro, isolated

Product information "1-Wire Bus Coupler USB Pro, isolated"

1-Wire Bus Coupler Pro with USB interface,
isolation and external power supply

With the professional 1-Wire Bus Coupler USB V3 a stable and electrically isolated connection of the 1-Wire network and a PC, mini computer (e.g. Raspberry Pi) or to many other controllers is established. The 1-Wire Bus Coupler USB is compatible with the serial version of Maxim, DS9097 and DS9097E, and works with a standard DS2480 1-Wire master device. By using the 1-Wire standard interface module (DS2480), the 1-Wire bus copller is compatible with all controllers that support this module. These are for example IP-Symcon, FHEM, OpenHub and many more.

A special highlight of the 1-Wire Bus Coupler USB V3 is the external power supply. This significantly increases the operational reliability of the data connection to the computer and prevents problems caused by unreliable USB power supplies. The use of more expensive USB hubs is no longer necessary.
For the 1-Wire network the 5V output voltage is provided. The insulation prevents interference from and to the PC and reduces possible "electrosmog" in the house. The insulation also increases electrical safety.
Individual 1-Wire sensors can be connected directly. For a 1-Wire network, the use of a 1-Wire hub is recommended.

Data interface USB 1.1, with FTDI FT232RL Chip (Virtual COM Port)
Compatibility To DS9097U 1-Wire Adapter Serial
Applicable for many software, such as OWFS, IP-Symcon, FHEM, which is intended for the DS9097U (DS2480 device)

Anschlussbelegung ungünstig

Der 1Wire-Buskoppler ist durch die Isolation besser als der alte Busskoppler. Es wurde jedoch die ungünstige Anschlussbelegung des alten Buskopplers übernommen. Der Abgang des 1Wire-Busses ist oben, wogegen die Buseingänge der Busmodule unten sind. Das macht die Verdrahtung unnötig kompliziert, da man den Bus um alle Module legen muss. Es wäre besser, wenn alle 1Wire-Anschlüsse auf einer Seite liegen würden.
