Product information "eBus to serial Coupler"

 eBus to seriell coupler

The eBus Coupler Serial provides read and write access to the eBus network. Thus with appropriate software it is possible to analyze all of your home heating system data and provide it with new operating data.
The E-Service eBus Coupler Serial provides galvanic isolation between the eBus and the PC serial interface.
The built-in software filter ensures that only payload data is transmitted over the serial interface. This filter significantly reduces the amount of data being transferred.
The eBus interface is reverse polarity protected. Therefore it is not necessary to observe signal polarity when connecting to the eBus. The Coupler’s enclosure is designed for mounting within a control cabinet.
The eBus coupler is equipped with an RS232 serial interface for transferring data to and from the PC. On the Coupler’s front panel there are LED indicators for “PWR” (eBus input power) and “DATA” (eBus activity). In the area of the eBus terminals there is additional a green LED which indicates the presence of an eBus. An external power adapter which is not included as part of the eBus Coupler delivery is required to operate the eBus Coupler.

Tip
eBus Coupler USB
eBus coupler USB: eBus to USB data interface for PC, Raspberry Pi and Co.Application With the eBus coupler you have read and write access to the eBUS e.g. of your heating.With appropriate software you can evaluate data of your heating and send new values via eBUS to your heating control. FeaturesThe ESERA eBus coupler is equipped with a galvanic isolation between eBus and PC interface.The eBus input is bipolar, so you do not need to pay attention to the polarity of the eBus when connecting.The housing of the eBus coupler is designed for control cabinet installation.As data interface to your PC, the eBUS coupler is equipped with a USB interface of the manufacturer FTDI. Drivers for Windows, Linux and further operating systems are available via the FTDI page.Note: The eBus coupler is not supported by Vaillant vrDIALOG software. A very good example (VWMon by Alexey Ozerov) for reading eBus data can be found among others here or the project Fhem here Note: We recommend to use a USB hub with power supply. This ensures a continuous power supply independent of e.g. a Raspberry Pi.
