DESCRIPTION
Each Model 110A is a two-channel physical layer
repeater for TP/FT-10 LonWorks networks. Data
received on one channel is reconditioned and retransmitted on the other channel. Each Model 110A
effectively doubles the wiring distance and the number
of nodes that can be placed on the network. On-board
jumpers allow each channel to be terminated
independently for bus or free topology.
protection using a self-resetting fuse. This provides
protection to the unit under most fault conditions.
A local 3.5 mm network jack allows a convenient way to
connect an installation or diagnostic tool to the network
without disconnecting any wires.
Three LED’s provide diagnostic information for
troubleshooting. A green LED indicates when power is
applied. Two red LED’s indicate when data is being
received on each of the two local channels.
The Model 110A operates from a wide range of low
voltage AC or DC power sources allowing it to be easily
added to existing systems. The power input has
transient voltage suppression as well as over current

Up to (5) Model 110A units can be daisy chained
together to create up to a (10) channel multi-segment
repeater. This is accomplished via a short jumper cable
between units. Data received on one network segment is
transmitted on all other network segments. This allows
the user to create a field expandable multi-segment
repeater from two to ten channels using a single product.
Note, the daisy chain feature of the Model 110A is not
on the network side but actually takes place on a
separate daisy chain bus between repeaters. This has
several advantages. One, there is minimal delay
between the received signal and the repeated signal.
Even with a ten-segment repeater (5 Model 110As), the
delay is equivalent to a single repeater. Two, each
network segment is completely isolated from all other
network segments. A short on one segment will only
affect that segment and not the others.

TP/FT-10 NETWORK TOPOLOGIES
The LonWorks TP/FT-10 network is designed to
support free topology wiring, and will accommodate
bus, star, loop, or any combination of these topologies.
Universal FT-10 Network Terminator which can be used
for either type.
Network devices using FT-10A transceivers can be
located at any point along the network wiring. This
capability simplifies system installation and makes it
easy to add nodes should the network need to be
expanded. The following sections present five different
network topologies.and how they should be terminated
using a single Free Topology terminator or two Bus
Topology terminators. Please see our Model 70
In the event that the limits on the number of transceivers
or total wire distance is exceeded, then the Model 110A
Repeater can be added to interconnect two network
segments doubling the overall system capability.
Each network segment connected to the
NOTE Model 110A must be properly
terminated as a separate network.

blocks. The top terminal block has two positions and
supplies power to the unit. 12-36 VDC or 9-26 VAC
can be used. The terminals are polarity insensitive.
Optionally, the Model 110 is also available with a much
wider input voltage range of 12-72 VDC or 12-50 VAC.
The bottom terminal block has four positions. Two
terminals for each network. The terminals for the first
network are labeled Network A1 and Network B1. The
second network channel is labeled Network A2 and
Network B2. The 3.5 mm network wiring is polarity
insensitive. The network jack provides an access point
for a network management tool. It can be used for
monitoring or configuration without the disturbing the
network wiring.
Mounting Options
The Model 110A is housed in a very compact DIN rail
mount enclosure that is only 36 mm (1.42”) W x 90 mm
(3.54”) L x 58 mm (2.28”) H. The enclosure snaps onto
an industry standard 35 mm DIN rail. The DIN rail and
Model 110A can be inside a weatherproof box for best
protection. Alternatively, the DIN rail and Model 110A
can be wall mounted if it is in a clean indoor
environment.

Up to 5 Model 110A Repeaters can be daisy chained to
form a ten-channel repeater. To operate properly in
multi-segment mode the user must observe the following
installation requirements:

All repeaters must be placed next to each other
and powered from the same power source.

All units that are daisy chained together must
be powered. A unit that is connected on the
daisy chain bus but not powered will cause
other units to fail. There is no physical damage
but the units will note operate properly.

LONWORKS TP/FT-10 MULTI-SEGMENT REPEATER
Each Model 110A is delivered with a short jumper cable
attached to the two daisy chain jumper headers. This is
simply a convenient place to store it. It is not needed
for proper operation if used as a standalone two-channel
repeater. The two daisy chain headers provide identical
connections. Two headers are needed to daisy chain
between more than two units.
The jumper cable is polarity sensitive and the
jumper cable is keyed and should only plug
onto the header in the proper orientation. If it
feels that it is not going on correctly, chances
are it is reversed.
Each segment should be properly terminated.
Termination Jumpers
The Model 110A has (2) 3-position jumper blocks as
shown below. Each of the network segments must be
properly terminated depending on how the are wired.
Please see the TP/FT-10 Network Typologies Section.
NOTE
If the particular network segment is to be terminated as a
bus, the repeater must be placed at one of the ends. Set
the termination jumper for that network to bus topology
and there must be an additional terminator at the other
end of the bus segment. Please see our Model 70 FT10
Universal Terminator if you require additional
terminators.
To access the jumpers, you must popoff the cover at the top of the enclosure
where indicated in the above diagram.
To change use long nose pliers without
power being applied.
NOTE
Each of the jumper blocks control the type of cable
termination at the Model 110A. If the network already
has terminators, the jumper for that network must be
removed inside the Model 110A or the communication
maybe degraded when you add the Model 110A to your
network due too many terminators.
The Model 110A is shipped with each
network being terminated as a Free
Topology network. This must be the
only terminator on the network

SPECIFICATION
System Performance and Cable Selection
TP/FT-10 network system and transmission
specifications are outlined on the following pages. Both
of these specifications must be met to ensure proper
operation. The system designer may choose a variety of
cables, depending on cost, availability, and
performance. Performance may vary with cable type.
The transmission specification depends on such factors
as resistance, mutual capacitance, and the velocity of
propagation. Currently, Echelon has documented
system performance on the cable types shown in table 1.

The free topology transmission specification includes
two components, which must both be met for proper
system operation. The distance from each transceiver to
all other transceivers and to the termination (including
the LPI-10 termination, if used) must not exceed the
maximum node-to-node distance. If multiple paths
exist, e.g., a loop topology, then the longest path should
be used for the calculations. The maximum total wire
length is the total amount of wire connected per
segment.
