To continue this.
I had the possibility to load the configuration again on the gateway and I also switched the programming DIP switch. Next problem is that the Neuron does not receive any data at all.

How should I configure the gateway? Any possbility to fix that without physical access?

@Martin-Kudláček @tomas_hora any suggestions

Hi,
I have the xG1W-2 One Wire gateway very successful in use. The configuration with the Software via USB connection is quite easy and works.
The problem is that the gateway seems not to read the values from connected sensors after a power cut. It could be that the gateway has lost its configuration. Currently it returns only -280 values to the Neuron.
This behaviour is not very usefull for remote installation without direct access.
How can I configure the gateway to store its configuration permanently?

Hi,
I fiddled around with the Matlab Mervis DB toolbox (https://kb.mervis.info/doku.php/en:mervis-db:10-api). Unfortunately i di not manage to download data from the database. The problem seem to be with the MexMain.mexw64 file. For the .mex file to run some dlls are required. Those can be installed with the Visual Studio C++ Runtime.
The problem is that the MexMain.mexw64 file is compile in debug mode not in release mode. For the debug version to run the original debug dlls are required.

Could anybody responsible provide me with a .mex-file compile in release mode? Or any other way to make it run.

Otherwise I would be happy about a solution to retrieve and manipulate data in the Mervis DB with either Matlab or Python

Hi,

I tried to get the 1Wire gateway xG1W-2 working together with the Unipi Neuron. As there unfortunately exist not tutorial on how to connect the gateway to the neuron and how to configure it inside Mervis I followed the same principles as connecting other extension modules but ran into problems.

1. Configured the gateway via usb using the corresponding tool. 1Wire sensors are detected and show values.
2. Connect the gateway RS485 D+ and D- to the RS485.1 A and B pins of the Neuron. Which principle does the A and B label on the Neuron follow? Is A + or B +?
3. In Mervis added new channel (Modbus Serial) and added the library device corresponding to the xG1W-2.

From here on Mervis could not successfully compile the solution because the an error that said the task count(1) is higher than allowed. After trying to compile the added Modbus channel shows no possible selection for the interface (RS485.1,RS485.2,...)

I would be very happy if anyone can help me with this problem or tell me how to get the 1Wire gateway working properly with the Neuron.

Thanks
