KB714 Loconet Overview

LocoNet is Digitrax's method of communication between LocoNet compatible 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 implementation is simple and wiring is free form with minimal limits. LocoNet is designed to run an unshielded 6 conductor ribbon cable.  Digitrax recommends using flat, six-conductor telephone wire ...

KB970 How does LocoNet Work?

LocoNet's "ethernet like" architecture seems interesting and more advanced than the systems used by other DCC manufacturers. But, at the numbers we are talking about (a few controllers and perhaps 10-20 decoders), does it really make a difference?If your system operates with a few throttles and other devices attached any of the commercially available systems will work today. But what about tomorrow? Remember when a hard-drive bigger than 32Mb seemed excessive- and remember when DOS had to change to 16bit FATs/ directories? Also, the LBA access change at 540Mb also once seemed unthinkable!!The network structure of LocoNet is very important ...

KB203 Case Study: Texas & Southwestern Part 11 of 11 - Future Expansion

As originally conceived, the Texas & Southwestern was set up with a very simple DCC system. The railroad uses a DCS50 Zephyr as its command station and booster. The Zephyr is connected to a central power bus, and all tracks, stationary turnout decoders and the automated reverse loop unit are connected to it. Likewise, the LocoNet connections are a series of simple cable connections starting at the Zephyr and ending at the last Universal Panel. The T&SW works well with this arrangement, but there are additional devices that will enhance the operation of this railroad. Digitrax PM42 Power Management System ...

KB205 Case Study: Texas & Southwestern Part 6 of 11 - Wiring the Railroad

KB613 Throttle Jacks vs. LocoNet Jacks

The jacks on the front and sides of the UP5, UR92, UR91, UR90, and LNRP front panels are Throttle Jacks and should only be used for connecting throttles to LocoNet.  They should not be used to connect to other LocoNet devices.  The jacks on the back of these units are LocoNet Jacks that are used for connecting LocoNet devices to the network.  Technically speaking! These units were designed to have the FRONT jack's second Railsync differential signal run as a diode-or'ed power source (for throttles).  This means that some cable orientations and power loads could cause unexpected operations in downstream LocoNet devices ...

KB490 LocoNet Architecture - Network Topologies

LocoNet is a peer-to-peer local area network, a communication network that is similar to communication networks used in today’s computer industry. There are five types of computer network topologies: star, bus, tree, freeform and ring.  The only prohibited configuration for LocoNet is the ring.  LocoNet should never be looped back on itself.Note: In the diagrams below, CS represents a Digitrax Command Station and the M represents any LocoNet compatible module or device.1.  The Star Topology is where all devices are connected to a central hub by individual legs. 2.  The Bus (Daisy Chain) Topology is where all devices are connected to ...
