Accessories > 1-Wire RFID readerIntroduction to the product
Compatible with: | TFT100 |
 One of the implemented features for fleet management devices is 1-Wire data protocol, which can be used to read RFID Tags by emulating them using iButton protocols. It is a convenient way to implement driver authorization in your vehicles if you want to use RFID Tags with minimal setup complexity.

Technical characteristics
| NAME | DESCRIPTION |
|---|---|
| Interface | 1-Wire Interface |

| Operating humidity | Up to 70% |
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.
| WIRE NAME of the TFT100 | WIRE NAME of the SENSOR |
DESCRIPTION |
|---|---|---|
| 1-wire Data | 1-wire Data | Outputs identification data via 1-Wire interface |
| 1-Wire Power | VCC (+) | Power supply for the sensor (requires at least +6.5V to boot-up, meaning external power supply will be required, since TFT100 works from 10V supply) |
| GND | 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.
