RUT240 Input/Output

Summary #

Inputs and Outputs are used for the monitoring and controlling of a connected device or receiving signals from that device in order to trigger certain events. This chapter is overview on the Input/Output section for RUT240 routers.

The information in this page is updated in accordance with the RUT2XX_R_00.01.12 firmware version.

Characteristics #

This section provides a list Input/Output electric characteristics inherent in RUT240 routers:

  • Digital non-isolated input (DIN1): Logic low 0 – 5 V; Logic high 8 – 40 V
  • Digital open collector (OC) output: 30 V, 300 mA

Status #

The Status tab displays the current states the router’s input and output:

Custom Labels #

If the default Input/Output labels do not suit your needs, you can always configure custom ones in the Custom Labels section. Click the ‘Edit’ button next to the desired Input or Output and you will be redirected to a window such as this:

The figure above is an example of custom label configuration for Digital Input. You can change an input’s/output’s name and the names of their states. The changes are purely cosmetic and used for easier management purposes.

Status and control from command line #

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

GPIO control aplication
        Usage: /sbin/ <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:~# 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:~# invert DOUT1
root@Teltonika:~# 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.

Input #

The Input tab is used to configure the router’s input pin.

Input Rules #

The Input Rules section provides you with the possibility to set up rules that execute user specified actions after a certain trigger occurs. To add a new rule, look to the Input Configuration section that is just below. Select the input, the trigger and the action for the rule and click the ‘Add’ button. A new rule will appear in the Input Rules list:

To begin editing an input rule, click the ‘Edit’ button located next to it. Refer to the figure and table below for information on input rule configuration.

Networking rut2xx manual input output input input rules input configuration v1.png
Enableyes | no; default: yesTurns the input rule on or off.
Input typeDigital; default: DigitalSelects to which input pin the rule will apply.
TriggerInput open | Input shorted | Both; default: Input openSelects which input state will trigger the rule.
ActionSend SMS | Send email | Change profile | Turn on WiFi | Turn off WiFi | Reboot | Activate output; default: Send SMSThe action that will be taken when the rule is triggered.Send SMS – sends an SMS message to a specified number(s) or user group. The message text is custom.Send email – sends an email to the specified address(es). You will be prompted to enter your email account’s authentication information.Change profile – switches to using another configuration profile. Configuration profiles can be created via the System → Profiles page.Turn on WiFi/Turn off WiFi – turns WiFi on or off.Reboot – reboots the router when a specified amount of time passes or instantly after the trigger occurrence.Activate output – activates the specified router output.

Output #

The Output tab is used to configure the router’s output pin.

Output Configuration #

The Output Configuration section is used to change the default state of the router’s output pin.

Open collector outputLow level | High level; default: Low levelChanges the default* state of the open collector (OC) output pin.

* Changing the default state of an output means that the changes will be written into the input/output config and saved. This means that unless some other related change occurs the state of the output will remain as set in this section.


The ON/OFF section is used to turn the router’s output on or off. This action does not save the state permanently, meaning that after a reboot the state will revert back to their default values.

Post/Get configuration #

Enabling Post/Get will allow you to send HTTP POST/GET requests to the router that control the state of the output. The figure below is an example of the Post/Get configuration section an the table below provides information on the fields contained in that section:

Networking rutxxx manual input output output post get configuration v1.png
Enableyes | no; default: noTurns Post/Get on or off.
Usernamestring; default: noneUsername used for authentication in POST/GET queries.
Passwordstring; default: nonePassword used for authentication in POST/GET queries.

Post/Get examples #

It is possible to turn the output on and off by using a valid HTTP POST/GET syntax. Use a web browser or any other compatible software to submit HTTP POST/GET strings to the device.

Below is a table containing syntax examples of this usage:

Turn output onhttp://
Turn output offhttp://
Turn output on after a 10 second delayhttp://
Turn output on for 5 secondshttp://
Turn output on for 5 seconds after a 10 second delayhttp://


  • – router’s default LAN IP address; replace it in accordance with your own configuration.
  • username – login name from Post/Get configuration.
  • password- password from Post/Get configuration.
  • action- the action that will be performed on the output (can be on or off).
  • pin – specifies the output (use oc).
  • delay – defines a delay (in seconds) after which the specified action will be performed.
  • time – defines a window of time during which the action will take place. For instance, if you post an on action while specifying time=5, the output will turn on and stay on for 5 seconds before turning off.

Delay and time parameters can be used together. For example, if delay is 10, time is 5, action is on, then 10 seconds after the execution of the command, the output will switch to on (or stay in on state if it was already that way), then after 5 more seconds it will switch to off state. In this case the overall command execution time is 15 seconds.

Periodic control #

The Periodic control section allows you to set up automatic output control rules that trigger output state changes at the specified period or interval. Refer to the figure and table below for information on configuration fields contained in that section.

Networking rut2xx manual input output output periodic control v1.png
Enableyes | no; default: noTurns the rule on or off.
OutputDigital OC Output | Digital 4PIN | Digital relay output; default: Digital OC OutputThe output pin that will be be effected by the rule.
ActionOn | Off; default: OnThe action that will be performed on the output.
Action timeoutyes | no; default: noAction timeout specifies whether an action should end after some time. For example, if action is set to on and timeout is set to 10, when the trigger occurs the output will turn on for 10 seconds before turning off.
ModeFixed | Interval; default: FixedWhen the rule will be triggered.Fixed – triggers the specified action on a specified day(s), hour and minute. For example, every Sunday at 8:30 AM.Interval – performs the action at an interval. For example, every 1 hour during Mondays.

Scheduler #

With the help of the output Scheduler you can configure a timetable of when the output should be enabled or disabled based on time.
