Question

Hello,
I have many teltonika gps trackers models FMB130 and FMC125 and digital flow meters  (SIKA VTY10) connected to arduino uno MCU for measuring water flow. Is there any way  the digital output sign from arduino to be read from the teltonika gps using rs485 input from FMC125 or directly from the sensor using the pulse input from FMB130 ?

At the moment, I convert the digital signal  of the sensor to an analog voltage with arduino and use the analog input of the tracker to read that voltage value.

Thanks in advance

Hello.

FMC125 has RS485 interface, so you can connect your device and use one of available RS-485 work modes:

https://wiki.teltonika-gps.com/view/FMC125_RS-232_and_RS-485

In FMC125 pulse counter can be used on DIN1

In FMC130 pulse counter can be used on DIN1 and DIN2

To use pulse counter feature on selected DIN, enable pulse counter I/O element in device configuration by setting its priority to Low/High or Panic
