'''Description:'''
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.
'''1-Wire RFID readers are great in these use cases:'''
*Immobilizer - prevent anyone from starting the vehicle without scanning an iButton first.
*Authorized driving - keep track of who is driving your vehicle according to the iButton ID they use to authenticate themselves.
*AutoGeofencing – gives ability to know when car leaves customized areas without iButton authorization.

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 VCC and connect the ground wire to the same grounding used for the device.

==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. <br><br>[[File:IButtonReaderConfig.png|border|frameless|682x682px]]

==Decoding RFID Card ID==
RFID Card ID should be entered into the iButton List correctly to make this feature work correctly. Please refer to the guide below on how to enter an RFID Card ID.
1. RFID Card Reader should be connected to the device according to the [https://wiki.teltonika-gps.com/view/1-Wire_RFID_Reader#Installation/ wiring scheme]. <br>
2. The device should be connected to the PC, and the Teltonika Configurator should be opened. <br>
3. Open the "I/O" tab and find the iButton parameter in the list (ID 50390). <br>
4. Attach the RFID card to the reader. The value in the configurator should change. <br> [[File:IButton_ID_detection.png|border|frameless|500x500px]]<br>
5. In this example iButton value is 01437829000700CF. The value should be converted to the format compatible with the Authorization List according to the figure below: [[File:iButton_ID_decoding.png|border|frameless|400x400px]]<br>
6. Converted value (CF00070029784301) can be entered into the Authorization List. <br><br>
'''NOTE:''' On FMX6 project devices, it works differently.
There is no need to make any changes whenever entering/receiving the iButton/RFID value
Note! This chapter describes the installation of an accessory supplied by Teltonika. Accessories from other manufacturers may require different steps.
To connect the accessory to your system:
Connect the ground wire to the same grounding used for the device.
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 VCC.
Relay is optional, driver authentication can work only with RFID

Tracker Configuration
Because this RFID reader emulates the received RFID values as iButton values, in configuration software it has identical functionality as the iButton reader.
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.
Converting IO values to IDs
This short guide explains how to convert the iButton value in "I/O" menu to an ID usable in the iButton list in "1-Wire" menu.
Note! For FMx6 trackers, you do not need to convert these values.
Connect your 1-Wire accessory to the tracker according to the wiring scheme.
Connect the tracker to a PC, run Teltonika Configurator.
Open the "I/O" menu and find the "iButton" parameter.
Scan the 1-Wire accessory on the reader. The value in Configurator will shortly change.
Take the value (here: 01437829000700CF) and convert it using the method shown below - then you will be able to use it in the iButton List.
