Installation
To connect the 1-wire RFID reader, simply connect the 1-Wire Signal wire from the reader to the 1-Wire Data pin on the device, connect the 1-Wire Power wire to the 1-Wire Power pin and connect the ground wire to the same grounding used for the device.
| PIN NUMBER | PIN NAME |
DESCRIPTION |
|---|---|---|
| 1 | 1-wire Data (Data Dallas) | Outputs identification data via 1-Wire interface |
| 2 | VCC (+) | Power supply for the sensor |
| 3 | GND (-) | Ground |
Device configuration
Since this reader emulates received RFID values as iButton values, it has identical functionality as the iButton reader in this regard. The reader works as soon as it is connected, but the iButton isn't used anywhere other than displayed in the iButton I/O element. In order to use it for the Immobilizer scenario, the device must have the scenario enabled. Then, iButton check can be enabled to only accept iButtons specified in the iButton list under the 1-Wire tab.
