5.6.1 RXB/RXL
device
address
with QAX34.3 room unit
The QAX34.3 room unit covers all the standard room unit functions. The room unit
can also be used to set the RXB/RXL room controller parameters via PPS2.
The QAX34.3 room unit is not suitable for direct connection to the KNX bus.
The tool socket (RJ45) on the RXB/RXL room controllers serves as a PPS2
interface and a bus interface (CE+ und CE-). This tool socket can be used to
connect room units (PPS2), the OCI700 service interface or the RMZ792 bus
operator unit.
