Hello,
I purchased a grove rs485 that i would like to use with a labjack T7, which doesn’t seem to work properly.
Measuring the signal, i realized that, only when connected to your device the low state is pulled up from 0 to 2.7 V, which of course is then interpreted as a constant high state.
what could be the reason for this behavior ? anything that I could try ?
thanks,
Yannick
