Model
110A: Multi-Segment FTT-10
Physical Layer Repeater
Datasheet
Description
Each Model 110A is a two-channel physical layer repeater
for FTT-10 LonWorks networks. Data
received on one channel is reconditioned and re-transmitted 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. 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
protection using a self-resetting fuse. This
provides protection to the unit under most fault conditions.
The Model 110A is a drop in replacement to our Model 110
product. A new feature in the Model
110A allows multiple repeaters to be daisy chained together to create
multi-segment repeaters. This
is accomplished via a short jumper cable between units. Data received on one network segment is transmitted on all
other network segments. For
example, assume three Model 110As are daisy chained together.
This equates to six total network segments since each repeater has two.
Data received on any one network segment is reconditioned and sent on the
other five network segments. This
ability 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.
