included with the product.
6.1 About Routers
Routers are used for applications that require network runs with large node counts, extreme
distances, and complex configurations.
Typically, a router is required under these conditions:
•
Any time more than 64 nodes are to be attached to a network segment.
•
When the segment needs to be more than 6000'.
•
When a free topology (star) configuration would be more efficient.
Routers regenerate the signal, resulting in no signal degradation. A router is an Echelon network
node that can be used to connect differing media types together or to extend the network. These are
the supported router types.
6.2 NCB-FL Product Description
This router is used to connect Echelon network media channels together via UDP/IP. The NCB-FL
is used to connect via fiber. This router uses Internet Protocol (IP) for data transport.
Communication between networks via NCB type router units is "live," delayed only by the transit
time through the routers and Ethernet channel.
At least two NCB-FL routers are required for each application, one located on the Echelon
Gateway side of the Ethernet network, and the other located at the other end of the Ethernet
network.
The NCB-FL router is an external router that communicates over Ethernet cabling with your LAN.
A dedicated fiber optic cable from the router's AUI port is used to make the connection to your
LAN. The router's factory installed SMX transceiver (NETWORK connector) is used to make the
connection to your Echelon network..
NOTE: Refer to the Intelligent Fire Integrator™ Echelon Gateway manual for information on SMX
Transceivers and segment termination.
NOTE: NCB-EL and NCB-FL routers use UDP messaging on ports 1100 and 1283.
