RUT950 Input/Output
The information in this page is updated in accordance with the RUT9XX_R_00.06.07 firmware version.
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 RUT950 routers.
Characteristics
This section provides a list Input/Output electric characteristics inherent in RUT950 routers:
- Digital non-isolated input (DIN1): Logic low 0 - 5 V; Logic high 8 - 40 V
- Digital open collector output (DOUT1): 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, the names of their states and which state is considered as "Active". 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 gpio.sh command. You can execute this command without any additional options to get usage syntax examples:
root@Teltonika-RUT950:~# gpio.sh
GPIO control aplication
Usage: /sbin/gpio.sh <ACTION> <NAME>
ACTION - set, clear, get, export, invert, dirout, dirin, getpin
NAME - SIM DOUT1 DOUT2 DIN1 DIN2 MON MRST DOUT3 DIN3 RS485_R SDCS HWRST
Where:
- 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 0
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 set DOUT1 root@Teltonika:~# gpio.sh get DOUT1 1
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.
| Field | Value | Description |
|---|---|---|
| Enable | yes | no; default: yes | Turns the input rule on or off. |
| Input type | Digital 4PIN; default: Digital 4PIN | Selects to which input pin the rule will apply. |
| Trigger | Low level | High level | Both; default: Low level | Selects which input state will trigger the rule. |
| Action | Send SMS | Change SIM card | Send email | Change profile | Turn on WiFi | Turn off WiFi | Reboot | Activate output | HTTP POST/GET; default: Send SMS | The action that will be taken when the rule is triggered.
|
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.
| Field | Value | Description |
|---|---|---|
| Digital output 4PIN | Low level | High level; default: Low level | Changes the default* state of the digital 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.
ON/OFF
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:
| Field | Value | Description |
|---|---|---|
| Enable | yes | no; default: no | Turns Post/Get on or off. |
| Username | string; default: user1 | Username used for authentication in POST/GET queries. |
| Password | string; default: none | Password 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:
| Action | POST/GET URL |
|---|---|
| Turn output on | http://192.168.1.1/cgi-bin/output?username=user1&password=user1&action=on&pin=4pin |
| Turn output off | http://192.168.1.1/cgi-bin/output?username=user1&password=user1&action=off&pin=4pin |
| Turn output on after a 10 second delay | http://192.168.1.1/cgi-bin/output?username=user1&password=user1&action=on&pin=4pin&delay=10 |
| Turn output on for 5 seconds | http://192.168.1.1/cgi-bin/output?username=user1&password=user1&action=on&pin=4pin&time=5 |
| Turn output on for 5 seconds after a 10 second delay | http://192.168.1.1/cgi-bin/output?username=user1&password=user1&action=on&pin=4pin&delay=10&time=5 |
Overview:
- 192.168.1.1 - 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 4pin).
- 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.
Click the 'Add' button to add a new periodic control rule and click the 'Edit' button next to it to begin configuration:
Refer to the figure and table below for information on configuration fields contained in that section.
| Field | Value | Description |
|---|---|---|
| Enable | yes | no; default: no | Turns the rule on or off. |
| Output | Digital 4PIN output; default: Digital 4PIN output | The output pin that will be be affected by the rule. |
| Action | On | Off; default: On | The action that will be performed on the output. |
| Action timeout | yes | no; default: no | Action 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. |
| Mode | Fixed | Interval; default: Fixed | When the rule will be triggered.
|
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.
