You can control and monitor input and output values via a command line interface (CLI) with the gpio.sh command. You can execute this command without any additional options to get usage syntax examples:

root@Teltonika:~# gpio.sh
GPIO control aplication
        Usage: /sbin/gpio.sh <ACTION> <NAME>
        ACTION - set, clear, get, export, invert, dirout, dirin
        NAME - SIM      MON     MRST    SDCS    CASE    DIN1    DOUT1


  • DIN1 - Digital input
  • DOUT1 - Digital output

For example, to get the status of the digital output use the following command:

root@Teltonika:~# gpio.sh get DOUT1

The return value 0 means that the output is in Inactive (Low level), i.e., OFF. You can turn it ON (Active (High level)) by setting its value to 1:

root@Teltonika:~# gpio.sh invert DOUT1
root@Teltonika:~# gpio.sh get DOUT1

As seen in the example above, you can change the value of an output by using the invert command, which simply turns the current value of the specified output and turns it into its opposite state.
