Dear ramaslabas, try to make yourself an very good converter which i use for years. Drawings, PCB and layouts in this post http://forums.mrplc.com/index.php?showtopic=10049 I wish you good luck.java script:emoticon('', 'smid_5') dekor.

dear friend, as you said earlier time, you want to communicate also with S5 controllers. For that option your laptop must have a RS 232 port (not USB to RS232 converter) plus RS232 to TTY converter. All the best. dekor.

I think you are not more interested about convertor. But anyway i will post also the electrical drawing.(maybe later......? ) So, new you have the el. diagram, PCB drawing, PCB layout. I think also is time to close this topic. dekor. Build_your_own_RS232_to_TTY_interface_to_communicate_with_STEP_5_PLC.doc
