Does not seem to be communicating with the DCC system. Using Windows 7 on a Samsung netbook. DecoderPro version 4.6-R8149dc. Computer interface is the RR Cirkits LocoBuffer-USB, Rev N. The driver installed successfully. Java version 8, update 141. The DecoderPro settings: DCC system: Digitrax Serial port: LocoBuffer-USB [com 3] Command station: DB150 [Empire builder] Connection prefix: L Connection name: LocoNet Do you have any idea what I am doing wrong, or not doing? Thanks. Steve
