Hello Karan,
Good day. Thank you for your question.
May I know what type of scenario are you referring to when you mention triggering DIN 2? What is the DIN 2 connected to, any accessory?
As for triggering DOUT 2, you can send the SMS command setdigout to the device, as follows:
If the device has only 2 DOUTs and you would like to deactivate DOUT 1 for infinite time and activate DOUT 2 for infinite time:-
With login and password : <login><space><password><space>setdigout 01
Without login and password : <space><space>setdigout 01
If you are sending via GPRS then you may skip the login, password, and <space>.
For more information, kindly refer to our Wiki page - https://wiki.teltonika-gps.com/view/FMB_setdigout
Hope this helps.
Kind regards.
