Description of serial interfaces:

Port 1: Serial interface X2

The potential-free RS232 serial interface at connector X2 supports the AEG-specific CBSER protocol for parameter setting and moni- toring purposes. Special service tools can be used to monitor and manage the equipment locally and (with the aid of the COM serv- er) remotely via a network. This is also the port used for configur- ing the assembly's interfaces.
