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.
