There are three main use cases for a relay
1. Double relay. <br>
1. Immobilizer relay. <br>
*You will need two relays, device that has two Digital Outputs and 1-Wire. The relay will be deactivated via driver authentication. <br>
*You will need one relay, device that has one Digital Output and 1-Wire. Тhe relay will switch via driver authentication. <br>
2. Inverted relay. <br>
2. Double immobilizer relay. <br>
*You will need one relay. Relay will be deactivated via SMS command. <br>

==Immobilizer relay scenario==
==Immobilizer relay scenario==
When DOUT 2 value is 1, ignition is blocked and the vehicle will not be started. When the iButton/RFID card is attached to the reader, DOUT 2 value changes from 1 to 0 allowing you to start the transport normally.

==Double immobilizer relay scenario==
The benefits of double relay scenario is double security.
If someone manages to bypass the vehicles alarm system, and unplugs the FM device the second relay will prevent engine start.
==Inverted relay scenario==
If you do not need driver authentication you can simply control the relay by SMS command ''setdigout'' from your phone.
