You can control and monitor input and output values via a [[Command line interfaces|command line interface (CLI)]] with the <i>gpio.sh</i> command. You can execute this command without any additional options to get usage syntax examples:

<pre>
root@Teltonika:~# gpio.sh
GPIO control aplication
        Usage: /sbin/gpio.sh <ACTION> <NAME>
        ACTION - set, clear, get, export, invert, dirout, dirin
        NAME - SIM      DOUT1   DOUT2   DIN1    DIN2    MON     MRST    SDCS    RS485_R
</pre>

Where:

<ul>
    <li><b>DOUT1</b> - Digital OC output</li>
    <li><b>DOUT2</b> - Digital relay output</li>
    <li><b>DIN1</b> - Digital input</li>
    <li><b>DIN2</b> - Digital galvanically isolated input</li>
</ul>
----
For example, to get the status of the digital OC output use the following command:

<pre>
root@Teltonika:~# gpio.sh get DOUT1
0
</pre>

The return value <b>0</b> means that the output is in <b>Inactive</b> (<b>High level</b>), i.e., <b>OFF</b>.

You can turn it <b>ON</b> (<b>Active</b> (<b>Low level</b>)) by setting its value to <b>1</b>:

<pre>
root@Teltonika:~# gpio.sh invert DOUT1
root@Teltonika:~# gpio.sh get DOUT1
1
</pre>

As seen in the example above, you can change the value of an output by using the <i>invert</i> command, which simply turns the current value of the specified output into its opposite state.
----
To get the value of the analog input use the <i>analog_calc</i> command. For example:

<pre>
root@Teltonika:~# analog_calc 
7.2V
</pre>
