Hello, I have just achieved a märklin interface 6051 but without any connecting cable (Between 6051 and computer - RS-232c). Does anyone know exactly which pins of the 6051 (6-pol DIN connector) should run to which pin of a 9-pol D-sub connector for a PC-compatible computer? This is RS-232C standard, and my question is basically which pin connections does the original connecting cable have (which I am missing) ? Anyone who has this old things and could meassure or help in any other way would be much appreciated, /Wurttemberg

Wurttemberg,
in the marklin 6051Interface manual is written:
DIN plug pin 1 to TD 2 Not used 3 to GND 4 to RD 5 to CTS (pin 6 is also not used)
Observe that one must also set the coding switches
Switch 1 for TD; on negative logic off positive logic 2 for RD; same 3 for CTS; same 4 for signal level: on TTL off RS232
The switch setting for a PC with standard RS232 is Switch 1 on 2 on 3 off 4 off
When you would like to have a picture of the cable wiring let me know. I can scan the manual pages.
Regards, Willem

It turns out there are several pin configurations on the 9-pin D-sub depending on which computer it is to work with. Thank you very much, Wurttemberg

Regards, Willem Hello Willem, Thank you for your answer, - My request was however the assignment of signals to the 9-pin D_sub connecter. But I realized that it depends on what kind of computer you are using. I have the manual, but thank you for your offer to scan! BR/Wurttemberg
