3.2 Networking Layout
K-BOW enables different networking layouts as shown in Fig. 2. The following applies:
C-hub
● The C-hub supports a star network:
● The Master C-hub can connect to a maximum of 2 slave C-hubs simultaneously.
● A maximum of 5 slave devices including E-hub and RU cascade per bre port of C-hub.
E-hub
● The E-hub supports a daisy-chained network (E-hub to E-hub) and a star-type network
(E-hub to HPRU).
● In smaller systems, the C-hub and RU can be directly connected without the E-hub, as
shown in Fig. 2.
● For a direct C-hub to RU connection, an RU can cascade up to 5 RUs at different levels.
For a C-hub to E-hub to RU connection, an RU can cascade up to 4 RUs at different
levels.
