Digitrax LT5C | 2-Pack LocoNet Cable Tester Module - Diagnose RJ12 Cables & Loco

Digitrax LT5C | 2-Pack LocoNet Cable Tester Module - Diagnose RJ12 Cables & LocoNet Bus Issues | Multi Scale The Digitrax LT5C is a handy LocoNet diagnostic tool — it plugs into any LocoNet jack and uses an LED indicator to verify that the cable, the jack, and the LocoNet bus power are all wired correctly. The LED lights up only when ALL six pins of the RJ12 jack get correct signal — making it the fastest way to find a bad cable, a miswired UP5/UP6 panel, or a broken LocoNet run before you spend hours debugging your throttles. This 2-pack gives you one to leave at the start of your bus and one to walk around with. Looking for more DCC tools and accessories? Browse our DCC Decoders and Electronics & Wiring collections. Features 2 LT5C tester modules per pack — one for each end of the bus, or one for the home base and one to walk the layout. Plugs into any standard Digitrax LocoNet RJ12 (6P6C) jack. Single LED indicator lights when all six pins are wired correctly — instant pass/fail. No batteries, no setup — passive diagnostic, draws power from LocoNet. Compact key-fob sized housing, slips into any toolbox or pocket.
