An Introduction to the Java Model Railroad Interface JMRI Victor Gilbert victor@sugarwood. info *Disclaimer This clinic is intended to provide information on getting stared with JMRI. The ideas and suggestions presented here are not the only way of accomplishing these tasks, they are merely the way I do it. I am not the “expert”. Contributions from the audience are welcome!!

What is JMRI? ● ● JMRI Stands for Java Model Railroad Interface The JMRI project is building tools for model railroad computer control. We want it to be usable to as many people as possible, so we're building it in Java to run anywhere, and we're trying to make it independent of specific hardware systems. JMRI is intended as a jumping-off point for hobbyists who want to control their layouts with a computer without having to create an entire system from scratch. You can manage your locomotive rosters and easily program your decoders using Decoder. Pro®. You can build control panels and control your layout using Panel. Pro™ to set up signaling. Operations. Pro™ lets you create manifests that route cars across your railroad from shipper to receiver, and provide train crews with operating instructions.

JMRI Requirements ● Runs on PC – ● The PC does NOT have to be a fast machine – ● MAC, Windows or Linux Operating Systems Supported For the DIYer a Raspberry Pi will work Must connect to the DCC System

What Can I Do With JMRI? ● Decoder Programmer – Common Locomotive Roster ● Universal Throttle ● Web Accessible Panels ● Locomotive and Rolling Stock Inventory ● Car Forwarding ● Automation

Consisting ● ● ● Basic Consisting Command-Station-Assisted Consisting Advanced Consisting

Basic Consisting Pros ● ● Cons Faster response ● Easy to move to different layouts ● ● All decoders respond to all function commands CV 29 may need to be different for each Locomotive in the consist Only one locomotive can be live on the track at a time

Command-Station-Assisted Consisting Pros ● ● Functions are sent to the lead locomotive only Locomotives still respond to primary address Cons • Must be programmed in to Command-Station on each layout. • Resetting the Command. Station may lose consist programming

Advanced Consisting Pros ● ● ● Fast response Cons • In general the consist number may not match a locomotive number • Limited to 127 consists • May conflict with Command-Station. Assisted consisting Easy to move to different layouts Not dependent on Command-Station

Decoder. Pro Consisting

Consisting Considerations ● ● Depending on DCC system Command-Station. Assisted consisting may use the Advanced Consisting CVs A Consist Roster will need to be matained Different model decoders may respond differently All locomotives in the consist should be Speed Matched

Speed Matching Photo by You. Tube contributor BArailsystem

Speed Matching ● Speed = The TIME to travel a given DISTANCE – ● Miles per Hours (MPH) / Kilometers per Hours (KPH) How do we measure Speed? – Mechanical – Stopwatch – I think that’s right

Mechanical Method Photo by You. Tube contributor BArailsystem Photo by Train. Electronics. com

Stopwatch Method ● ● ● MPH / KPH = 3600 divided by the TIME (in seconds) to travel 1 Mile / Kilometer Measure the TIME it takes to travel a given Distance - 6 inches (1. 8 Seconds) Divide a Mile / Kilometer by the Distance from Step 1 (5280 * 12) / 6 = 10, 560 ● TIME (1. 8) * 10, 560 = 19, 008 ● 3, 600 / 19008 = 0. 1893 MPH ● 0. 1893 * SCALE (HO 87. 1) = 16. 4 MPH

NMRA Scales

“I thinks that’s right” Method ● Create a Golden or Master locomotive ● Match locomotives together

Getting Started ● ● Choose Speed Table or Basic Speed Control Set throttle position to the point the locomotive should start moving Basic Speed Control – Adjust VStart until locomotive moves slowly smoothly – Adjust Vhigh for locomotive’s top speed – Set Vmid to a mid range value Speed Table – Adjust Left most slider until locomotive moves slowly smoothly – Adjust Right most slider to the locomotive’s top speed

Basic Speed Control
