Hello there,
Good day. Thank you for your question.
If you would like to use both the features (Immobilizer & SECO) then you will require 2 DOUT's (1 for each). So for cars, I will suggest using FMB120. For motors, you may use FMB120 but bear in mind that FMB120 is only IP41 (

Also, take note that to use the SECO function, you will require a specific firmware version that is not in the base firmware. To obtain the firmware, you may either contact your Sales Manager or Distributor from whom you purchased the device. If you don't have any contacts with our sales managers, please contact them on our official website
https://teltonika-gps.com/ and click on the "Contact Us" button. When you click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to info@teltonika.lt
Thank you in advance.
Kind regards.
