==Tracker Configuration==

| RFID = 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. [[File:IButton_ID_detection.png|right|400px]]
# 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.
