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 ?.
