the FT Router 5000 IC, the FT-X3 communications transformer,

a crystal to generate the clock and an external serial 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 a half router that uses the Router 5000 and an

external transceiver such as RS-485, TP-1250, TP-78, FTT-

Router 5000 IC can also be used to implement the FT section

of a FTPL router along with the PL 3150 Smart Transceiver to

implement the PL section. Additionally, the FT Router 5000 IC

offers higher reliability since two half routers of a full router are

logically isolated and a failure in one half router will not affect

the other side’s network.

to work with routers. Only the network configuration of a

device has to be modified when a device is moved to the far

side of a router. The required modifications to the network

configuration can be done automatically by an installation

tool.

Routers are also independent of the network variables and

message tags in a system, and can forward an unlimited

number of them, which saves development cost because no

code development is required to use routers in a system.

It also saves installation and maintenance costs because

router configuration is automatically managed by network

server tools based on OpenLNS. Monitoring and control

applications, such as those based on the LCA Object Server

OCX, do not require modifications to work with multi-channel

networks when routers are used. All network configuration

is performed over the installed network, further minimizing

installation and maintenance costs because routers

do not have to be physically accessed to change their

configuration.

Table 1: FT Router 5000 Chip Pin Assignments

Below is a table of the pin assignments for the FT Router

5000 chip. All digital inputs are low-voltage transistor-

transistor logic (LVTTL) compatible, 5 V tolerant, with low

leakage. All digital inputs are low-voltage transistortransistor

logic (LVTTL) compatible, low leakage, 5V-tolerant. All digital

outputs are slew-rate limited to reduce Electromagnetic

Interference (EMI).
