USB MPI Cable pin out

Hello All

first post so be gentle

I am having difficulties connecting to a CPU315 2DP 

I am using a usb MPI adaptor but unfortunately the cable with the 9 pin connectors is missing, i have tried a straight through cable, it is showing the MPI, power and USB leds are on but i cannot get connection, I am starting to think that the straight through cable is not correct

I have tried every consievable setting for the adaptor, MPI, Auto, different baud rates, profibus master, node addresses, so this is the last thing i can think of

If someone could post the pin outs for this cable i will have to make one as i am currently on board a vessel at sea, so going to the shop is not an option, 

thank you in advance

Hello,

USB MPI cable is wide info, but exactly order number of your adapter can be helpful. Also if you put that number to Google, you probably find all what you need

part number for adaptor is 6ES7 972-0CB20-0XA0
