Inc LocoNet Cable Maker Kit - Manual

10. DO NOT leave the LT1 connected to a running layout, because it adds

an extra unnecessary load to LocoNet. It is meant to be used as a

simple temporary diagnostic tool only.

LocoNet, the Digitrax Dierence

LocoNet is Digitrax’s method of communication between LocoNet com-

patible devices on a model railroad layout. LocoNet Compatible devices

are designed to work together on the network, and in some cases can also

accept DCC commands from the track, but often go beyond the scope of

simple DCC train control.

LocoNet is a peer-to-peer Ethernet type multiple access network. Because

of its design architecture, it is very robust and powerful. Layout imple-

mentation is simple and wiring is free form with minimal limits.

LocoNet is designed to run on an unshielded 6 conductor ribbon cable.

Digitrax recommends using at, six-conductor telephone wire and RJ12

6P6C connectors for LocoNet wiring. This is a simple, cost eective way

to wire LocoNet for excellent network performance and reliability.

Using shielded twisted pair conductors or Cat3, Cat4, Cat5 and above will

degrade LocoNet data performance and limit maximum wire footage that

can be installed on the network. This type of wiring is not recommended

by Digitrax because of its limitations.

The 6 LocoNet conductors are: two ground return connections (Pins 2

and 5), two data network signal connections for LocoNet message ex-

changes (pins 3 and 4), and two RailSync lines for signals that are mirror

copies of the system DCC or other digital track control packets (pins 1

and 6).

With no message trac, the two LocoNet data wires should measure

approx. +12V DC with respect to LocoNet ground.

The RailSync lines communicate a copy of the track signals to the Boost-

ers for amplication and transmission to the rails. RailSync lines can

power a limited number of LocoNet connected devices on small layouts.

As the number of power consuming LocoNet devices attached to LocoNet

increases, the need to separately power those devices increases.

RailSync is a low power signal that mirrors the DCC packets on the rails.

It is generated by the Command Station and sent out via LocoNet (pins

1 & 6) to devices such as Boosters, Occupancy Detectors and any other

device which require RailSync to operate. Boosters receive the RailSync
