Should it be necessary to add more nodes
or wire runs in excess of 500 meters, link
power segments can be interconnected by
a router or a physical layer repeater.
Model 50040R-02 is compliant with the
European Directive 2002/95/EC on the re-
striction of the use of certain hazardous
substances (RoHS) in electrical and elec-
tronic equipment. The LPT-11 transceiver
includes an integral switching power supply
that requires minimal external components
to furnish +5VDC at up to 100mA. This
current is typically used to power a Neuron
Chip and application electronics, sensors,
actuators, and displays. The high current
capability of the LPT-11 transceiver elimi-
nates the need for local power supplies
at each node, resulting in equipment and
labor cost savings.
Using the LPT-11 transceiver can save thou-
sands of hours of development time com-
pared with designing a custom transceiver.
The transceiver is designed to comply with
FCC Part 15, Level B, and CISPR 22 Level
B regulations, minimizing time consuming
and expensive laboratory transceiver test-
ing. As a UL, CSA, and TÜV recognized
component, the LPT-11 transceiver can be
integrated into a product with minimal ad-
ditional safety testing. The transceiver is
small enough to fit into virtually any appli-
cation, and is economically priced for OEM
applications of any volume.
Echelon offers a comprehensive range of
development tools, network interfaces,
routers, and network services tools to sim-
plify the task of designing products using
the LPT-11 transceiver. Technical support
for the transceiver is available through
Echelon’s LonSupport™ Premier technical
assistance program.
