The Loco Control Box

The Locomotive Side box

The locomotive side control box is the “brain” of the system and takes inputs from the handheld wireless controller, brake current and speed sensors, battery monitors and the motor controller to make your locomotive operate as you request. Here are the connections seen above

  • KSI & +12V - The system runs on 12v DC power and this is the connection for that, along with a KSI plug. The 12VDC is either supplied direct from the battery (in a 12v system) or through a converter (sold separately) that will supply it 12v stepped down from your locomotive’s supply voltage.

  • LIGHTING - The lighting plugs are for front and rear headlight, which are independently controllable and dimmable and the ditch lights (if your locomotive is equipped).

  • AUXILIARY - 3 auxiliary outputs are also available that can operate things like marker lights, strobes, class lights, body lighting, etc. These are configurable in the handset menu and can be made to operate in conjunction with other operations (horn, etc) or can be used as simple “on/off” switches.

  • AIR BRAKE - These are the outputs for the air brake control valves. Working in conjunction with a pressure sensor, they provide a pressure maintaining function for the brake pipe.

  • AUDIO OUT - This RCA jack is to supply power from the onboard amplifier. It can also be configured to provide line level output to go to a more powerful audio amplifier.

  • MULTIUNIT - This is the plug socket for the MU cables. They go to each end of the locomotive to connect via a jumper cable to the next locomotive.

  • SENSORS - This is where the brake, current and speed sensors connect to the locomotive. These sensors are supplied with the unit and provide the system with the data to make your locomotive operate in the desired manner.

  • RADIO - This port connects to the radio module. The radio can be be mounted anywhere in the locomotive, but should be near the antenna unit.

  • BATT MONITOR - This port connects to the battery monitors. This provides accurate battery levels on individual batteries in your locomotive so you can monitor your overall battery level and specific battery levels to give you a reading on battery health.

  • MOTOR CONTROL - This connects the system to your motor controller via the supplied interface cable.
