Overview

The MRC PRODIGY DCC system is an advanced, user-friendly Digital Command Control (DCC) system designed to enhance the enjoyment of model train layouts. It allows for the control of up to 32 locomotives, enabling multiple users to participate in running trains simultaneously. The system consists of a console (base unit), a handheld controller, and a power supply.

Function Description

The core function of the PRODIGY DCC system is to send Digital Command Control (DCC) signals to decoders installed in locomotives, controlling their movement and allowing for programming. The console acts as the command station, while the handheld controller is the primary interface for most operations. Up to four handhelds can be plugged into the base unit, with additional handhelds available for purchase.

The system operates in three main modes: Run mode, Program mode, and Consist Setting mode.

  • Run Mode: This is the primary mode for operating locomotives. In Run mode, users can acquire and control individual locomotives by selecting their address, adjusting speed with the throttle, changing direction, and operating headlights and accessory functions (F1). The system supports controlling both standard locomotives (always assigned address #1) and decoder-equipped locomotives. For emergency stops, a dedicated Stop button halts all operations, indicated by a blinking green LED. Operations can be restored by pressing the Start button. The system also features automatic overload protection, where power to the rails is cut, and both orange and green LEDs blink. Power is restored once the overload is removed.

  • Program Mode: This mode is used to program a decoder's address and other operational data. To enter Program mode, a handheld must be plugged into jack #1, and the mode switch on the base unit must be set to Program. The Program light will illuminate to indicate active Program mode. A dedicated program track is recommended for programming to avoid affecting other locomotives on the main layout. Programming involves placing the locomotive on the program track, selecting the desired address on the handheld, and pressing the Program Address button. The locomotive will briefly jerk to confirm successful programming.

    Key programming features include:

    • Program Loco Address: Assigns a unique address to the decoder. Decoders are factory-programmed to address #3 by default.
    • Program Start Voltage: Adjusts the voltage required for the locomotive's motor to begin moving, allowing for smoother starts.
    • Program Top Voltage: Sets the maximum speed (voltage) at full throttle. This is particularly useful for switchers to achieve more realistic low-speed performance.
    • Program Momentum: Simulates the drag of a heavy train, allowing for more realistic acceleration and deceleration. The higher the setting, the more momentum is added.
    • Program Reverse Polarity: Reverses the direction setting of a decoder, useful for multi-lashup locomotives operating back-to-back. Reprogramming the address will revert to normal direction.
    • Program Analog Enable: Allows a decoder-equipped locomotive to run on a standard analog (DC) layout. Reprogramming the address disables this feature.
  • Consist Setting Mode: This mode is used to create, modify, or clear consist groups (multi-lashups) of locomotives. To enter Consist Setting mode, the Consist Setting button is pressed, and the Consist Setting light will glow. In this mode, locomotives can be added to a consist by dialing their address and pressing the Add Loco button. The last added locomotive becomes the lead loco, controlling the speed and direction of the entire consist. Locomotives can be deleted from a consist, or the entire consist can be cleared. Consist settings are temporary and are cleared when the power switch is turned off. The system supports up to four independent consist groups, one per input jack.

Usage Features

The PRODIGY DCC system emphasizes ease of use. Each handheld controller includes simplified "QUICK START" instructions on its reverse side, allowing users to quickly begin operating trains.

  • Handheld Priority: When multiple handhelds are connected, a priority system is in place. Handheld #1 (plugged into jack #1) has the highest priority, and handheld #4 has the lowest. A higher-priority handheld can take over control of a locomotive acquired by a lower-priority handheld. To avoid confusion, users are advised to unplug their handheld or acquire a non-assigned address once they have finished controlling a locomotive, especially if they are using a lower-priority handheld.

  • Memory Capabilities: The system retains the last direction and speed of a locomotive even if the controlling handheld is unplugged or acquires a new loco, provided no other handheld acquires that locomotive.

  • Reverse Loop Operation: The manual provides instructions for setting up a reverse loop using a double-pole double-throw (DPDT) switch to manage track polarity. For automatic operation with decoder-equipped locos, the MRC Auto Reverse Loop Module (AD520) can be used.

Maintenance Features

The manual includes a troubleshooting section to help users diagnose and resolve common issues.

  • Troubleshooting Steps:

    • Check Address Bank: Ensure the correct address bank (1-16 or 17-32) is selected on the handheld.
    • Clean Track and Wheels: Dirty track and locomotive wheels are a common cause of intermittent or jerky operation in DCC systems. Regular cleaning is recommended.
    • Decoder Lost Memory: If a locomotive loses control, reprogramming the decoder is suggested.
    • Check Decoder Connection: Inspect the decoder's wiring inside the locomotive for any loose or broken connections.
    • Console/Handheld Lights Flash, Power Lost: This indicates a short circuit or an overload. Removing the short will automatically reset the unit. If heavy loads are consistently causing overloads (e.g., running more than 6 HO locomotives), a Power Booster (AD501) can be added to provide more current.
  • Service Information: For issues that cannot be resolved through troubleshooting, the manual provides contact information for customer service. Users are advised to read the troubleshooting section first and have specific information (power supply model, shipping address, phone number, and problem description) ready before calling. If a return is necessary, detailed packing instructions are provided to ensure the unit's safe transit.
