the PLC i use is a CJ1M
Dip switch 5 is in the OFF position.
Now I have put 000D in the field of Set End code.
I know that the port is not standard. I have made changes to the port, i think it should work. I can send something with TXD so i think the port is good.
It still dont work, but now i can receive '.0' as show in the picture.
