Hi, I'm trying to get a weather station to communicate with my touchberry 7 " via rs485, I set the jumper to half duplex and the two jumpers in point 2.2 of your manual as RS485 configuration, I connected data + on A and data- on B, on node red I using the serial in node set as the weather station booklet (9600 baud, 8 data bits, no parity, 1 bit stop) the interface is / dev / ttyS0 as your manual. When I power on the meteo station I must receive a series of characters but I am not receiving anything. Am I doing something wrong or forgetting something?
