SPROG DCC Installation Instructions

Thank you for purchasing a product from the SPROG family, The DCC Decoder Programmer.

Please take the time to read through these instructions fully before attempting to install or use your SPROG.

The following steps are required to install your SPROG before you can use it for the first time:

  • Install the Java Runtime Environment (JRE) if not already on your system
  • Install JMRI including DecoderPro and PanelPro
  • Connect the Power Supply
  • Install SPROG II or SPROG3 USB drivers (if required)
  • Edit DecoderPro Preferences
  • Connect the Programming Track

These instructions provide full steps for the Windows, MacOS or Raspian operating systems but the same basic principles apply to other Linux distributions.
Specific instructions are included for Raspberry Pi 4B (or 3B+) running Buster or later.

Should you have any questions during the installation process, please contact us using the link on the left (requires e-mail and internet connection), or separately send email to sprog@bbmgroup.com.

Before you begin you will need:
  • A SPROG II, SPROG 3, SPROG Nano or Pi-SPROG 3, and appropriate computer conection (typically USB cable supplied)
  • A 12-18V regulated DC power supply (as supplied, 12V 1A (SPROG II) or 15V 3A (SPROG 3 or Pi-SPROG), not required for Nano)
  • Java 11 Runtime software (download link here)
  • JMRI software (included here on the later pages, or USB Flash drive)
  • USB drivers if needed (included here on later pages, or USB Flash drive)
