    The LM-3S-21 is a module that you can install into a model train locomotive so the locomotive can be controlled and setup by a Ring Engineering RailPro Controller, such as the HC-3 Handheld Controller with a Color Touch Screen! After the LM-3S-21 is installed in a locomotive, you will be able to control the locomotive speed, direction, up to 12 light outputs and sounds! The LM-3S-21 has “Direct Radio” (RF transceiver) built inside. The built in RF module allows commands and data to be sent and received to and from the module. You can load a picture of your choice into the LM-3S-21 module.  Then you will be able to touch the screen of the HC-3 to take control of your locomotive! You can even download new sounds and light effects using the built in Direct Radio! The LM-3S-21 is electrically compatible with the DCC plug found in many locomotives to promote easy installation. Product Specifications: Sound Profile: Universal (all) Dimensions: 1.23 x 0.65 x 0.25 in Light Outputs 12    The LM-3S-21 is equipped with Direct Radio + NET! This allows Ring Engineering Controlling Devices such as the HC-3, Handheld Controller with Color Touch screen, to control and configure your locomotive by sending and receiving data directly to the LM-3S-21 through the air by use of RF transmission! The Direct Radio + NET is very fast giving your locomotive quick response to your controls. Further, a controlling device can detect your LM-3S-21 with just a few touches on the screen. Because of Direct Radio, you can load a picture of your locomotive to the LM-3S-21! You can also load Sounds, Light Effects and much more!Your LM-3S-21 is equipped with Rail Sonic HD Sound System!  This is Ring Engineering's proprietary technology that allows your LM-3S to produce realistic locomotive sounds! Radio Load Sharing is a truly an innovative invention from Ring Engineering.   It allows your locomotives that are linked together (sometimes called Consisted or MU'ed) to actually share pulling power.  Only RailPro equipped locomotives use Direct Radio to talk to each other to be sure each locomotive pulls its share of the load! Even more amazingly, Ring Engineering's patent pending process only takes seconds to setup! Twelve light outputs.  Can be configured for multiple light effects on a single output including On/Off, Dim, Ditch, Mars, Strobe, and more!  Additional light effects can be loaded using Direct Radio + NET! Built in protection with fault reporting by Direct Radio + NET! Tiny size 1.23 x 0.65 x 0.25 Inches for easy fit.

    Enjoy complimentary shipping!Bundle your purchases for even more savings with our free shipping option. (This offer is optional) Blunami will change the way you enjoy the model railroading hobby! The Blunami BLU-2200The BLU-2200 is a universal-style sound decoder that can be operated in three different ways: DC, DCC and Wireless mode. Using the Blunami app (iOS versions 8 or later), you can operate your locomotive with incredible ease of use. This decoder is suitable for use in both HO and small S-scale models.  DYNAMIC DIGITAL EXHAUST For added realism, you’ll love SoundTraxx's reactive Dynamic Digital Exhaust (DDE) feature that automatically notches your models engine up or down depending on the load on the motor. With the Blunami App, DDE calibration has never been easier. When your locomotive is traveling across flat terrain and simply maintaining speed, you will hear your locomotive chugging along. But, when the locomotive encounters a grade and the engineer applies more throttle to get the train up the hill, the engine sounds will automatically react and reflect the increase of power needed to crest the hill. DDE accomplishes this by calculating the changes in strain or load on the motor and adjusting the exhaust to appropriately simulate the work the engineer would be doing to the throttle of the engine. This gives Blunami the ability to create the most realistic experience possible. HIGH QUALITY SOUND LIBRARYSoundTraxx's large selection of high quality sound effects include:  10 Exhaust Chuffs Up to 12 Prime Movers in each sound profile  Up to 12 Bells  90 Whistles 40+ Airhorns Additional couplers, dynamos, cab chatter and more! ADDED REALISMAdditional realism can be simulated by adding functioning locomotive and train brakes, injectors, power reverse, firebox flicker and more. EASY INSTALLATIONThe BLU-2200 can simply plug into models equipped with a DCC quick plug. Our 9-Pin JST to NMRA 8-Pin Wiring Harness (P.N. 810135) can also be used to plug the BLU-2200 into models equipped with an NMRA 8-Pin plug. The BLU-2200 can also be wired into a large variety of models. This 2-amp, universal-style format, and includes a connector to easily add a CurrentKeeper (P.N. 810140 or 810160) to maintain performance over dirty track and switches.
