Pro-Bel SW-P-02 (General Switcher) protocol for router control is supported in Helm, RouteMaster and RouteMaster VR
RouteMaster uses the protocol for both outgoing and incoming connections, allowing third-party systems using SW-P-02 to control RouteMaster. Helm uses it for outgoing connections to control routers.
Because it does not support name transfer, it’s less commonly used than Pro-Bel SW-P-08 protocol
SW-P-02 has no concept of levels. However, Helm and RouteMaster both automatically map high-numbered destinations to higher levels, based on the router size. For example, if you configure a router with 32 outputs and 2 levels, outputs 32 to 63 – as sent via the protocol – are used to represent the second level. Only the destination numbers have this mapping – source numbers are unchanged.
