The command station processes, assembles and routes information to either the track and/or LocoNet. It is a separate circuit from the track power used to run model trains.ĭigitrax developed LocoNet to handle the communications between throttles, accessory decoders, and other devices that need communications with the command station. LocoNet is a Peer-to-Peer Local Area Network (LAN) designed for very high traffic capacity and free-form wiring, future system expandability and ease of upgrade. LocoNet is part of a Digital Command Control system designed by Digitrax to connect throttles, boosters and other devices to the command station.

LocoNet is similar to the standard ISO Network Model with pipelined multilevel protocol stacks and queues.LocoNet is designed to allow operation at 100% capacity with fewer than one collision in 300 messages, less than Ethernet allows.Collision Detection: When two devices try to send messages at the same time, creating a conflict, that they resolve those conflicts on their own.Multiple Access: The ability of all devices to access the network and generate messages on their own, without direction from a central controller.The devices also know when the network is busy. Carrier Sense: Message sync is done within the message stream as all devices on the network see all the messages transmitted.LocoNet is a networking technology that uses CSMA/CD (Carrier Sense Multiple Access/Collision Detection), similar to the Ethernet network commonly used to interconnect various network devices, such as computers, high speed modems, printers, etc., but optimized for model railroading.
For more information on interfacing a computer to your Digital Command Control system, please see Connecting your computer to DCC Network Details LocoNet can interface with a computer via a a device such as the LocoBuffer or Digitrax's own PR3, PR4 or MS100 interfaces. It is also possible to use a computer with multiple ports to route and bridge messages across several LocoNets, expanding capacity. LocoNet is designed for future expansion, where today's devices will still be able to process messages even if they cannot use it. Prior to the year 2000, the system functioned at less than 20% of available message types and commands that LocoNet is designed for. Portions of LocoNet® are covered by US Patent Number 6,275,739. LocoNet® is a trademark identifying a LAN for model railroads designed and patented by Digitrax Inc.
