-The decoder is an Lua applet that creates a BSC endpoint dynamically sending a xAPBSC ON event when the device is first registered.  As long as the device updates itself within 35 seconds, the endpoint will remain alive.  When the device moves out of range a reaper will take care of expiring the endpoint sending an xAPBSC OFF event and removing the endpoint.+The decoder is a Lua applet that creates a BSC endpoint dynamically sending a xAPBSC ON event when the device is first registered.  As long as the device updates itself within 35 seconds, the endpoint will remain alive.  When the device moves out of range a reaper will take care of expiring the endpoint sending an xAPBSC OFF event and removing the endpoint.
