Description of serial interfaces:

Port 1: Serial interface X2

The potential-free RS232 serial interface at connector X2 is

setting and monitoring purposes. Special service tools can be used

to monitor and manage the system locally and (with the aid of the

COM server) remotely via a network. This is also the port used for

configuring the assembly's interfaces.
