The controller module has an Ethernet interface with the following functions:
• Transfer of the configuration from MSI.designer to the program removable storage
• Reading of configuration from program removable storage in MSI.designer

Connector/bushing
RJ45
The device itself detects which cable type, patch cable or cross-link cable, is being used (Auto MDI-X),
which is why the pin assignment does not matter with regard to the RD or TD signals.
