Intelligent Building Series C-Bus Network Interface Installation Instructions
1.0 Product Range
5500CN C-Bus Network Interface
2.0 Description
The Network Interface is a C-Bus system support device designed to provide an
isolated communications path between an Ethernet 10BaseT Network and a C-Bus
Network. For ease of installation the unit is DIN rail mounted measuring 4M wide (1M =
17.5 +0.5/-0.0mm)
3.0 Capabilities
The Network Interface provides the gateway between an Ethernet Network and a C-Bus
Network. Through this interface the following functions can be achieved:
1. Programming C-Bus Units,
2. Issuing commands to a C-Bus Network, including scheduled activities,
3. Monitoring and Data Logging of activities on a C-Bus Network
The Network Interface may also generate the system clock for communications data
synchronisation on the C-Bus Network and provide a software selectable Network Burden.
NOTE: When using C-Bus Installation software V2.20 or earlier, additional ‘Com Port Redirector’
software will be required.
4.0 Indicators

Orange/Green flash C-Bus clock present, C-Bus voltage good,
active comms to Ethernet side
5.0 Clock Signal Generation
The Network Interface incorporates a software selectable C-Bus System Clock, used
for synchronising data communications waveforms on the C-Bus Network. Selecting
this option on the ‘Global Tab’ of the Graphical User Interface (GUI) will enable this unit
to generate a C-Bus system clock signal on the network (if one is not detected).
