Frequently Asked Questions:

Q1. What are the basic functions of the NDBU-95C?

The NDBU-95C is a passive, multi-port network branch/hub unit. Its core function is to provide physical connection points for ABB's DDCS network (e.g., for peer-to-peer communication between Symphony system controllers or for connections to I/O units).

2. What does the "9-channel" of the NDBU-95C specifically mean?

The 9-channel refers to the fact that the unit provides 9 identical physical connection ports.

Each port is a 9-pin D-sub connector.

One port is typically used as a backbone port, connecting to the upstream branch unit or network master controller.

The remaining 8 ports are used as branch ports for connecting downstream DDCS devices.

This design allows a single unit to connect up to 8 devices and can be cascaded to expand the network size.
