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 a

dapter „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.

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.

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:
