Thank you ,is female adapter ?. I also used as this to read modbus huminity and temerature but the value results were 0 so that I tested backward from rs232 to TTL (Max232) then connecting TX,RX at the MAX232 to verify ,the result did not show as the last so I think the result must be same as at the rs232 port so in this case can use MAX232 or can any ?.
