Good day. Thank you for your question.
We will need to test the hydraulic PTO switches because the voltage values are small, it will be connected to the analog input. Therefore, for testing purposes please contact your Sales Manager. If you don't have any contacts with our Sales managers, please contact them on our official website https://teltonika-gps.com/
and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with description of your situation to firstname.lastname@example.org
Thank you for your understanding.
