Hello

Thanks for your question

If you properly connect the device to the vehicle installation via relay.

You will be able to use DOUT1 output and command sms:

setdigout 1 (high state) enable GND

setdigout 0 (low state) disable GND

SMS Command structure

<SMSlogin><space><SMSpassword> <space> command

If you don't use a login and password

<space> <space> command

FMB 920 has only one DOUT1 output so you will only solve one scenario.

You can also use this scenario

(authorizing the vehicle to start via iButton or iBeacon)

I got this reply: 'DOUT1:1 Timeout: INFINITY but the car was not demobilised. The installer said he connected the relay to fuel. Do you think this could be the cause.

Hello

The answer you have received confirms the activation of the DOUT => ON output (mass indication).

If the device is properly connected to the vehicle's installation, you may prevent the vehicle from starting. (you need to verify it)
