Product Introduction
NDBU-95C 3AFE64008366 DDCS Branching Unit (DBU) is used (for DCS 600/DCS800) to implement the star topology of the DDCS link. This allows a slave unit to fail or become unpowered without disabling the communication. The NDBU receives messages from the master (PC) and sends them to all the slave units simultaneously. Each slave unit has an individual address, and only the addressed slave unit sends a reply message to the master. It is also possible to use NDB, thus enabling peer-to-peer communication.

Product Details

NDBU-95 DDCS Branching Unit has nine output channels where messages from the master are sent. The reply message sent by one slave unit is delivered to the master, er and it can also be delivered to other slaves if necessary. Several NDBU-95s can be used in parallel, in series, or in any combination of these. The maximum distance between the master and NDBU-9.5, as well as between two NDBU-95, is shown in the manual Branching units NDBU-95.DDCS Branching unit NDBU-95
