In order to follow these test guidelines, make sure first to follow the TUTORIAL 4373 - OneWireViewer and iButton Quick Start Guide.
Once you have followed the tutorial and if you still are not able to interact with the iButton please proceed with the following tests:
Adapter test:
1. Connect only one Adapter without launching the OneWireViwer (OWV) GUI. For this example, we used the USB Adapter DS9490R#.
2. Launch the Default 1-wire Network Setting GUI (Default 1-Wire Net.exe shown below)
3. Once the Default 1-wire Network Setting GUI launches, then select the adapter you are using and click the Auto Detect button and let the GUI proceed.
Once the GUI finds the first and only USB adapter connected, a sign will show up prompting that an adapter was found. This prompt will be similar for other adapters.
Proceed by clicking the Yes button.
4. The GUI will prompt you that the Auto Detect sequence finished and you can click OK and proceed to close the application.
5. Now you should be able to launch the OneWireViewer (OneWireViewer.jar) and with an iButton connected to the Blue dot receptor, which is also connected to the DS9490R USB adapter.
The USB adapter and the iButtons show up in the OWV GUI.
- NOTE: What you should see in the OWV software is something similar to the following:
- The following capture shows the first Item is the RTC iButton DS1904 (same family as DS2415 RTC) and the second item is the DS9490R USB adapter identified with a 1-wire serial number DS1990A (some adapters do not include an ID chip, like the DS9097U - S09#). The subsequent items in the Device List are the iButtons used in this example.
6. If you have several adapters connected to the computer repeat the same steps for each adapter. Make sure you close OWV GUI and remove the adapter every time you start from step one.
Blue Dot Receptor test:
1. The Blue Dot receptors can be tested with a simple Digital Multi Meter doing a continuity test. You may need to use a fine tip probe or tie a piece of small wire around one of your probes to test the RJ-11 connector end, and just probe the other end of the blue dot receptor wires to see if you have continuity. You can see that there are only two connectors in the RJ-11, which correspond to Data and Ground. Likewise, the Blue Dot receptors have a large diameter contact on the edge (GND) and a small one in the center (DATA).
2. Blue Dot receptors do not have any smarts built-in, so they cannot be identified by the OWV software GUI.
iButton test:
1. Once you have checked that your USB adapter and the Blue Dot receptor are working, then you can see if the iButton in question is being detected by the OWV as shown in the previous images.
2. If the iButtons are not brand new or acquired form an unauthorized reseller, then there may be a possibility that the battery is depleted, damaged, or not an authentic part. In order to identify any errors or possible battery damage we suggest to read APPLICATION NOTE 5057 - OneWireViewer Tips and Tricks.
