I have a problem where the counter increments about one click per second after connection just the F terminal to a reed switch flow meter, doesn't make a difference if second wire is connection to 5V. After some Googling I was able to get the meter to work by adding a "pull down resistor" between G and F. I don't know the exact resistor to use, so tried 2.2k and 820 ohm and they both worked. So my flow meter is connected to F and 5V with the pull down resistor between F and G, with about 200ft of ethernet cable to Flow Meter using just a single pair. I have also found that connecting G to Ground works. So my question is what is the recommended way to go here?
