Router Function
The router contained in each NCB module may be configured as a repeater, bridge, or configured router. The
easiest configuration is as a repeater, where all messages which enter the NCB module (via any of the three data
sources described above) are simply passed to the other two sources, regardless of the domain, subnet/node, or
group destination address. A bridge only passes messages that match one of the two domain IDs configured on
the router. A configured router only passes messages that match a domain ID as well as a set of subnet or group
numbers. The proper choice of router mode depends on desired simplicity of installation versus required
system performance.
