Тhe advantages of a relay are that even if the thieves managed to bypass the cars alarm system by using modern jammers, or even unplug the FM device they won't be able to start the engine.

There are three main use cases for a relay

−
1. Immobilizer relay. <br>
 
−
*You will need one relay, device that has one Digital Output and 1-Wire. Тhe relay will switch via driver authentication. <br>
 
−
2. Double immobilizer relay. <br>
 
−
*You will need two relays, device that has two Digital Outputs and 1-Wire. The relay will switch via driver authentication. <br>
 
−
3. Inverted relay. <br>
 
−
*You will need one relay. The relay will switch via SMS/GPRS command. <br>

The benefit of this connection is that every driver will be autorizated before he can start the engine.

−
For different scenarios you can use iButton, RFiD or Beacon (for beacon authorization you don't need DOUT or 1-Wire, the scenario work via Bluetooth)

===Device connection===
 
−
For configuration example we will be using FMB120 and RFiD
 
−
 
−
1.      Connect your FMB120 device to power supply
 
−
 
−
*     <span style="color:red"><b>Red</b></span> wire on the positive contact of the power supply
 
−
 
−
*     <span style="color:black"><b>Black</b></span> wire on GND of the power supply
 
−
 
−
2.      Connect your device to PC and open FMB120 configurator software to configure required fields for Immobilizer scenario.
 
−
 
−
You need to configure your device to read iButton/RFID card data and set immobilizer settings correctly.
 
−
 
−
===Immobilizer scenario configuration===
 
−
 
−

−
<p style="text-align:center;">'''Figure 1'''. FMB120 Immobilizer scenario configuration
 
−
 
−
<p style="text-align:left;"> Navigate to Features panel, locate Immobilizer feature and configure Immobilizer settings as shown in the Figure 1. <br>
 
−
1. '''Scenario settings''' – When low priority event is triggered, device makes additional record with indication of event cause. <br>
 
−
2. '''Eventual Records''' - Select "Enable". When "Enable" value is selected, scenario status will be sent to your server only when it is triggered. <br>
 
−
3. '''Output Control''' - you need to select which DOUT will be activated. In this case Digital output 2 will be activated if event happens. <br>
 
−
4. '''List Check For Authorization''' – this parameter lets the user use this scenario for authorization.

−
<p style="text-align:center;">'''Figure 2'''. Ignition source configuration
 
−
 
−
<p style="text-align:left;"> Go to system tab and look at the Ignition Source. We recommend to use DIN 1 as ignition source for this scenario.

===Authorized ID List===

−
<p style="text-align:center;">'''Figure 3'''. Authorized ID List
 
−
 
−
<p style="text-align:left;">Go to  Authorized ID List settings tab. There you can see Authorized IDs List which is used to enter authorized IDs codes. Codes are used to authenticate user in immobilizer scenario as shown in Figure 3. For example, if you enter the wrong RFID card ID here, you will not be able to deactivate configured digital output. Below you will see a guide for RFID card ID decoding.
 
−
 
−
===How to decode RFID Card ID with Configurator===
 
−
 
−
1. Connect the device with RFID Card Reader to the computer using USB cable and open configurator.
 
−
 
−
2. In the configurator, open „I/O“ tab and find iButton in the list
 
−
 
−
3. Attach the RFID card to the RFID Card Reader and check what ID is generated under „Current Value“ column near iButton parameter.<br>
 
−
 
−
[[File:IO elements.png|500px|thumb|center]]
 
−
<p style="text-align:center;">'''Figure 4.''' iButton ID detection
 
−
<p style="text-align:left;">4. In our case, the generated ID when we attach the card is: 01437829000700CF. <br>
 
−
5. To get the RFID Card ID in a proper format for list checking, type the ID from the back to front taking 2 digits at a time. (Figure 5.)

<p style="text-align:center;">'''Figure 5.''' iButton ID decoding
 
−
<p style="text-align:left;">6. The ID we get from Figure 5 (CF00070029784301) is the ID of our RFID Card that we need to use in iButton List. Enter the ID in iButton list.
 
−
<br />
 
−
 
−
===Stage 2. Connecting device to relay and iButton/RFID reader===
 
−
 
−
1.      Connect FMB120to you power supply:<br>
 
−
 
−
*     Connect FMB120 positive cable to positive power supply contact (red wire).<br>
 
−
 
−
*     Connect FMB120 GND cable to GND power supply contact (black wire).<br>
 
−
 
−
2.      Take relay, and connect wires in this order:<br>
 
−
 
−
*     86 (White wire) connects to 12V cable (both, FMB120 and power supply)
 
−
 
−
*     85 Dout (Black) connects to DOUT 1 or 2 of FMB120 (in this instructions we will use DOUT2 purple cable)
 
−
 
−
*   87a (Relay red cable) Connects to DIN1 (yellow) of FMB120
 
−
 
−
3.      Take iButton or RFiD card reader and connect their wires in this order. (in this case we use RFiD card reader)<br>
 
−
 
−
*     Green cable connects to GND cable of FMB120 and power supply.<br>
 
−
 
−
*     Brown cable connects to 12V cables, FMB120, power supply and Relay.<br>
 
−
 
−
*     White cable connects to 1-wire (green) of FMB120<br>
 
−
 
−
5.      Connect micro USB cable to FMB120 and your computer.
 
−
 
−
6.      Turn on your power supply.
 
−
 
−
7.      Connect Blue cable of relay (30 starter control) to positive power supply contact using additional cable.
 
−
 
−
8.    Open the configurator and go to status window I/O info section. In Figure 7 you can see Ignition value is 1 and digital output 2 value is also 1, digital input 1 value should be 0 (if you connect relay to DOUT 1, then you will see the value in Digital output 1 section).

<p style="text-align:left;">In figure 7 you can see Ignition value is 1 and Digital output 2 value is also 1, digital input value should be 0 (if you connect relay to DOUT 1, then you will see the value in Digital output 1 section). <br>
 
−
 
−
9. Touch RFID card with the RFID Card reader, and after that in the configurator status window you should see that Digital output 2 changed it’s value to 0 ant digital input changed it’s value to 1. As shown in Figure 8. <br>

<p style="text-align:left;">10.  To check if your RFID card reader or iButton works you can go to I/O window and find iButton parameter as shown in Figure 9. <br>

−

<p style="text-align:center;">'''Figure 9'''. iButton ID

−
<p style="text-align:left;">When you touch the RFID card (or iButton) to RFID card (or iButton) reader these parameters should change to your iButton’s ID:

<p style="text-align:left;">'''Operation example:'''<br>
 
−
 
−
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==
 
−
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==
 
−
If you do not need driver authentication you can simply control the relay by SMS command ''setdigout'' from your phone.
