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.
