• The current version of srcpd (2.1.1) is not as robust as it could or should be. The changing of certain parameters within Rocrail such as loco speed steps usually requires a restart of the srcpd process(s) and Rocrail. This behavior is due to the limitations of srcpd and not Rocrail.
• To select 1:1 addressing for switches, select the "Single Gate" option in the Interface tab.
