PC/RS232 Siemens Converter

[mohamedzobaa]

I found the converter 6es5 734-1bd20 in the store of my company. I don't use it before but i know from search in web that this is for step 5 programing.
My questions are:-
1- How can i connect it with PC (DB 9male)?
2- What is the pin assignment for the cable i need to
make it?
3- Is there pin assignment for it to check if it works
or not?

Hello Mohamed;

The cable 6ES5 734-1BD20 is not a standard RS-232 cable, but a RS-232/TTY (current loop) converter cable, used for the programming port of S5 CPUs (protocol AS511).
The posts in this thread confirm the diagram that dimmarkov presented in his reply:
