Good day. Thank you for your question.
I will suggest connecting to DIN 1/DIN 2 instead. So in the Configurator, you will need to enable the Pulse Counter DIN1 or DIN2 depending on which is used. DIN gives 0 and 1, so in a sense, the change between 0 and 1 is a pulse. We have separate IO elements which count those pulses. See the image below for the I/O settings that need to be enabled in the Configurator.
Please note that each digital input has its own threshold. For more information, please refer here - https://wiki.teltonika-gps.com/view/Impulse_counter
