UR93 Setup and Operation: 31Aug2021- IPL-version 1, Improved UR92 inter-operation timing margins and locking Channel and NetName. 1) Like all Duplex units, the UR93 is configured with a unique 8 character Digitrax Duplex NetName and a RF Channel number from 11 to 25. Any Duplex throttle unit trying to access LocoNet with a particular UR93 must have exactly matching NetName and Channel number as the UR93 it is trying to use for Duplex connectivity. Any differences will break a duplex link. 2) UR93 and UR92 units will automatically invoke a NetName and Channel resolution protocol when a LocoNet Power On <83><7C> message is seen or it is powered up. On some layouts, usages, configurations and combinations of UR93's and UR92's, if this resolution is unsuccessful the UR93 or UR92 may suddenly seem to freeze or stop working on an untethered; UT4D, UT6D, DT402D, DT500D or DT602D. 3) To avoid connection problems, after you setup required UR93's Duplex settings to run the layout, best practice is to set OPSW11 =C to turn OFF Channel Changes and OPSW12= C to turn OFF NetName Changes. This will ensure the Duplex settings cannot be modified in operations, and the UR93 will then not be involved in NetName and Channel resolution. 4) To subsequently edit system Channel/NetName you will need to temporarily set OPSW11/12 back to T to allow changes. 5) A UT6D or DT602D plugged into LocoNet with UR93 and UR92 units can conveniently edit NetName, Channel and also Key settings of any units that allow changes of these settings. Press menu>3>6 and follow the prompts. You may also use the free Digitrax Duplex Setup PC application to do the same thing. 6) Any Duplex enabled throttle plugging into LocoNet will use the first Duplex Channel and NetName received. If there are differing sequential values of these seen, it may lead to some confusion. 7) For remote joining, or diagnostic purposes, with untethered UT6D or DT602D units you may invoke the Duplex RF Scan capability with menu>3>5, and then the soft key "Scan All". After the scan time, you will see a list of Digitrax Duplex beacons visible from UR93 and UR92 units, so you can be sure what is currently available, look for any unexpected setting changes, and also can then use a soft key to join a visible network. 8) In a system with mixed UR92 and UR93 units, the UR93 have about 33x more transmit power and also about 33x higher receiver sensitivity and so longer beacon range. Duplex throttles track and change to beacons of the same Channels and NetName with the strongest RF signal, so most throttles will usually track the beacons of UR93 units. Duplex links are "connectionless", so a single UR93 can handle an "unlimited" number of duplex throttles' RF traffic sequentially. 9) It is recommended that all UR93's be updated with the latest IPL on the Digitrax web site. The latest UR93 IPL version has improved legacy UR92/Duplex timing tolerances and also implements a new IPL-version number that will uniquely identify the IPL version related to the IPL date code, when using the DigiIPL II v2.9.1 downloading utility program. An IPL_ver number of 0 means the current UR93 installed firmware does NOT support IPL-version capability. Downloading the latest UR93 firmware will enable IPL-version display

From the show website: Every year late in January or early in February, the Amherst Railway Society holds its Railroad Hobby Show at the Eastern States Exposition Fairgrounds (The home of The Big E) in West Springfield Massachusetts. More than 25,000 railfans and public attended the Show each of the past three years. The event features real life railroads and scale model railroads, historical societies, travel agencies, art shows, flea market dealers, importers, manufacturers and photographers. Modelers' exhibits will display outstanding handiwork on layouts ranging from the tiny Z scale which fits on a coffee table to a monster 80 foot N-Trak system. The Amherst Belt Lines, an HO scale model railroad empire, has become a show highlight. As of the 2011 show layout, It has grown to over 11 scale miles of mainline (650+ feet of mainline track) on 96 modules and has the capacity of multiple train operation. The Southern New England O Scalers will show its huge O gauge railroad with 100 car freight trains and 7 unit diesels. Live steam will also be shown. The Dry Hill Club will once again break records with 250+ car trains! Commercial vendors and hobbyists will sell model railroad equipment, photos, slides, video tapes, books and other railroad memorabilia. New and antique railroad items will be on display and for sale. Major national manufacturers and publishers will attend this Show which was rated number one of the top three in the nation in a recent Model Railroad Industry Association manufacturer's survey. Watch for new product releases by many of our fantastic manufacturers! Proceeds from the show are used to promote interest in railroads. Donations have been made to various rail museums, historical societies, restoration projects and scholarship funds. Over $600,000 has been awarded since 1991. Organizations that have received donations include: the Fall River and Old Colony Museum, the 470 Club's Boston and Maine diesel locomotive restoration project, the Boston and Maine Railroad Historical Society, the Chester Foundation Station Project and the Wiscasset Waterville and Farmington Building and Car Fund, just to name a few recipients. Trolley museums in the following towns have also received donations: Shelburne Falls MA, Warehouse Point CT, Branford CT and Kennebunk ME. We have also made contributions to the Boston and Maine 3713 restoration fund and the Flying Yankee restoration.
