S7-200 Ppi Cable Pinout

[Giorgio Aguilar]

Ihave a Magelis HMISTU855 and i'm trying to connect it to a S7-200 PLC via a XBT ZG929 MPI-Bus adapter. To do that i have a stripped RJ45 cable to whom i need know how to make the wire connection in a D9 connector, in order to match the pinout of the MPI-Bus adapter.

unfortunately I can't find the connection between the pinout of the connector with the one of the cable. I know the red wire is the VDD and the pin 1 but the others? Are they consecutives? like the second wire from the red one is the pin2, the third the 3 etc?

IDC socket connectors like these pretty much always have triangle symbol in the plastic, acting as arrow, pointing at pin 1. You'll find it on either side of the red strip, quite likely at the same side as the notch.
