DCC Sniffer

Dotric DCC Sniffer is a Windows application that is intended to be connected to an NCE DCC Packet Analyzer to view the DCC codes actually being sent to locomotives on a model railway layout running DCC.

Since Dotric DCC Sniffer is intended primarily for use with Dotric Station Blue systems, it does not display NCE Cab Bus activity. It can however be used to display track activity for any NMRA compliant DCC system.

The advantages of using Dotric DCC Sniffer include:
  • DCC messages are displayed in human readable form
  • Messages sent to individual locomotives are displayed on separate tab pages
  • Program mode messages are displayed on a separate tab page
  • A high performance serial port interface is used to provide a responsive user interface
