I need your help with an issue. We need to connect a server station with an CP1613 A2 and an CP443-1 (PLC S7-400) by means an OLM v2.0 (as is shown in the archive attached). That connection must be done using a Sinec H1 Bus (mandatory physical layer)

We have cables with connectors DB15 in both sides (one side is useful for the CP443-1), but the OLM has only ports with DB9 connectors, so we tried to make a cable DB15-DB9 following the pinout of DB15 and DB9 connectors (founded in siemens support's pages) only connecting the RX+, RX-, TX+, TX- but it didn't work.

Thanks in advance.

in advance thank you very much.
