IMPORTANT: This user manual only covers the use of LM-4S-G with an analog controller. Please see LM-4S-G user manual for applications like Radio Controlled, Battery powered, DCC controlled etc. Below is a link to a list of power supplies that Ring Engineering has tested with RailPro locomotive modules. https://www.ringengineering.com/PowerSuppliesTestedWithRailProLocomtiveModules.htm Specifications Maximum Power Input Voltage: 28 Volts (Absolute Maximum voltage 30.0V)
Connecting a LM-4S-G output directly to a smoke unit that needs a circuit board to protect the smoke unit from burning out, can damage the smoke unit and may become a fire hazard.

Step 3 – Mount the LM-4S-G in your Locomotive IMPORTANT: Module must be mounted level with the RailPro logo pointing straight up in order for it to have proper heat dissipation.

MPM wires (Plug in MPM module and connect +5V and Com wires). TIP: It is recommended to connect the front and back lights to the LM-4S-G module because LM-4S-G controls them with fade on and off light effects which is more prototypical than being controlled from analog voltage.

Step 7 – Connect Speaker(s) An 8 ohm speaker that is rated for less than 7 watts or a 4 ohm speaker that is rated for less than 13 watts may be damaged by the LM-4S-G and could become a fire hazard.
MPM. The LM-4S-G in this kit is programmed to have the MPM enabled and input #1 is set to play the Bell and Input #2 is set to play a crossing sound. You can use the Computer Interface (Model #CI-1) to change the MPM #1 and #2 inputs to play whatever sound or turn on whatever light effect you want.
Since the single knob controllers force you to go to zero speed (zero volts) before changing direction, the sounds stop and restart when you change directions which is not prototypical. Ring Engineering Inc...
All you need to do is turn your analog power supply most of the way up (do not exceed LM-4S-G maximum voltage rating) and use the Handheld Controller to run your trains! So simple and so...
Programming the Locomotive Module You can use the Ring Engineering Computer Interface (CI-1) and Ring Engineering PC Software to change the sounds and other settings. The CI-1 is a USB dongle that adds RailPro Radio Communication to a PC. Sounds such as the bell, horn, primemover etc, can be changed.
