Proven, Safe Choice
The FT Router 5000 IC is an Echelon
semiconductor product that is used to build
half routers and full routers. The FT Router
5000 IC is based on the Echelon FT 5000
Smart Transceiver and can be used to build
a FT-10 channel halfrouter with LONWORKS^®
communication channel to route LonTalk^®
messages. An Echelon router can support
installation of networks with up to
thousands of nodes.
The FT Router 5000 IC includes the Router
firmware required to implement a half
router. Its compact form factor minimizes
the space required to develop a half router.
Customers can develop two half routers to
build a full router. Customers will need to
use the FT-X3 communications transformer
to connect to the network. The Router
parameters are stored in an external
EEPROM with a minimum size of 2 KB. For
a full router design, customers can use the
same crystal and the same power supply
to implement the clock needed for the two
half routers. This offers the flexibility for
customers to incorporate the FT Router
5000 IC into their design for a higher level
of integration.
The FT Router 5000 IC can use one of
four routing algorithms: configured router,
learning router, bridge or repeater. The
ability to choose these options allows the
customer to trade off system performance
for ease of installation.
Configured and learning routers fall into
a class of routers known as intelligent
routers, which use routing tables to
selectively forward messages based on
the destination address.
A router configured as a bridge forwards
all valid packets that match its domains,
whereas a router functioning as a repeater
forwards all valid packets. Configured
routers are easily installed using an
installation tool such as the OpenLNS
Commissioning Tool and OpenLNS network
operating system that calculates network
topology and layer 4 timing parameters.
Usage
A FT Router 5000 based FT-10 channel half
router consists of the FT Router 5000 chip,
the FT-X3 communications transformer,
a crystal to generate the clock and an
external memory to hold the router table.
Two such half routers are used to build a
full router. A half router design that uses
FT Router 5000 can be used with another
half router to function as a repeater or
interface with other twisted pair physical
media such as RS-485, TP-78, TP-1250 or
LPT-11. It can also be used to implement
a FT-PL router using the PL 3150 Smart
Transceiver. The two half routers of a full
router are logically isolated so that a failure
in one half router will not affect the other
side’s network.
