4.1.3 Embedded Signals
If optional add-on modules are used, signals such as e.g., audio (analog, serial, digital or symmetrical) or USB 2.0
are transferred to the underlying extender module and embedded as well as transmitted via the link connection to the
CON Unit. The embedded signals are extracted in the CON Unit, transferred to the add-on module above and output
there separately.
