Hello JuanC,
Good day. Thank you for the question.
For FMC130, there are 3 DOUTs. Therefore the command must specify all 3 DOUTs in the command.
For example, if you would like to have all 3 DOUTs to be activated for infinite time then you can send the following SMS command:
<space><space>setdigout 111 (for GPRS command, you can skip the spaces so it will be setdigout 111)
if you would like to have DOUT1 to be activated for infinite time and DOUT2 and DOUT3 to be deactivated for infinite time then you can send the following SMS command:
<space><space>setdigout 100 (for GPRS command, you can skip the spaces so it will be setdigout 100)
Also, keep in mind that for the GPRS command to be sent, the Codec12 protocol must be implemented. You can learn more on Codec 12 here, https://wiki.teltonika-gps.com/view/Codec#Codec_12
For more information on the setdigout command, you can refer at https://wiki.teltonika-gps.com/view/FMB_setdigout but please take note of the commands based on the number of digital outputs (DOUTs). You can also add timer and speed thresholds to the commands for a more explicit command to the device.
Please go through this link and let me know if it helps. Thank you in advance.
Kind regards.
