This compact tester checks LocoNet cables for proper wiring and lets you bench-test mobile decoders before they ever go near a locomotive, so problems get caught at the workbench instead of in the middle of an operating session.\u003c\/p\u003e\n\u003cdiv class=\"sectionTitle\"\u003eWhat's in the Box\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eLT1 tester board with four diagnostic LEDs and a female 6-pin RJ12 jack\u003c\/li\u003e\n\u003cli\u003eTest harness with 6-conductor telco wire, male RJ12 plug, and a 100-ohm 2-watt protection resistor\u003c\/li\u003e\n\u003cli\u003ePrinted instruction sheet covering both cable and decoder testing modes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"sectionTitle\"\u003eWhy Hobbyists Reach for the LT1\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVerify LocoNet cables in seconds.\u003c\/strong\u003e Plug a cable between the LT1 and any powered Digitrax command station or booster, and all four LEDs light up when the cable is good.
