Morning ,I have test already the result is OK ,can comunicate with modbus device (temperaure and huminity) ,firstly ,tested with Max232 then the result was OK and step to test by RS232/485 connecting to modbus device the reading parameters were shown .
Still want to ask you why your RS232 on board device desing is FEMALE (difficult to find the converter and use more converters too so mostly MALE and USB is Micro it should Micro.
Mostly design pin 2 is RX.
Thank you.
