    An unsynched sleeping node, newly powered, will wake and poll for a synch message and then return to sleep, repeating the cycle until it becomes synched by receiving a synch message. Once synched, the node will wake to exchange messages for the programmed time interval and then return to sleep. © 2008 Digi International, Inc.      16 Downloaded from Elcodis.com...

    The commands for programming sleep time intervals are • SP - sleep time • ST - wake time. Starting a Sleeping Network By default, all new nodes operate in normal mode.
