Whurry,
Yes, JMRI uses a separate prefix to differentiate items on one physical connection from items on another physical connection. They are separate ¡°System Name¡±s, so they are treated entirely separately from the JMRI perspective.
For example, an NCE throttle can control Switch 12. A Digitrax throttle can control Switch 12. The NCE throttle operates the ¡°Switch machine¡± associated with the DCC track signal sourced by the NCE command station. The Digitrax throttle operates the ¡°switch machine¡± associated with the DCC track signal sourced by the Digitrax command station, or associated with a LocoNet device that acts upon control messages to ¡°Switch 12¡±. The two physical devices are typically not cross-connected, so each system controls its own resources.
In some cases, the JMRI user may force a direct relationship between an NCE object and a Digitrax object of the same number. Making this direct relationship requires some special configuration in JMRI (Logix or scripting or other ¡°tricks¡±). I think it is rare for a JMRI user to implement such schemes, but I¡¯m sure we¡¯ll hear it if it is more common than I think.
Digitrax command stations can support ¡°Turnout¡± numbers between 1 and 2044, but Digitrax throttles generally can only access turnouts between 1 and 999. Any LocoNet turnout address greater than 999 can not be directly accessed by a Digitrax throttle. (This is intentional, as it prevents user control of ¡°signals¡±.)
Digitrax numbering can be difficult to get your hands around, to say the least. Digitrax ¡°addressing¡± and its effects on JMRI are discussed more completely in the JMRI help page for LocoNet ¡°addressing¡±: .
