  1. Hi, I am trying to use PmodRS485 with Arduino Due for communicating with a sensor that uses MODBUS RTU (RS485). My question: Is PmodRS485 the right module to use in this case? (I am not able obtain any data from the sensor. The voltage between A and B terminal on PmodRS485 remains constant. That means it is neither sending nor receiving anything. I am using the ModbusMaster.h library by Doc Walker.)
