I'm trying to use the modbus gateway on a RUT955 (firmware RUT9XX_R_00.06.06.1). I have a modbus RTU temperature sensor. I recover the temperatures in a random way (sometimes I recover the value, sometimes not).
According to your wiki, it is necessary to use a termination resistor. Unfortunately, I don't see this resistor on my PCB :
Thank you in advance for your help.
