2.1 Network Bridge Applications
Therearethree main types ofapplicationsthat a networkbridgemayprovideina commercial
installation,
theyare:
1. ConnectivitybetweenCNIC‐Busnetworks.
2. C‐Busnetworkextender.
3. C‐BusCommandFilter.
2.1.1 ConnectivityBetweenC‐BusNetworks

This means that a C‐Bus command that is generated on one network will be routed across the
Network Bridge onto another C‐Bus network. This is particularly useful when routing
