Connecting a commissioning and service tool or service terminal to the tool socket on
the receiver provides access to the connected room controllers.
The bus cable (terminals 3 and 4) is looped through to the tool socket (pins 1 and 2) for
this purpose. The bus cable is not affected by the receiver.
The PPS2 interface is also routed to the tool socket, enabling a service terminal to be
connected.
