How do I turn my logger into a Repeater in order to build a mesh network? |
|
When the logger is online, right-click the logger icon in DataNet’s Map View and select the Enable Short Range Repeater Mode option (SSR Mode). When in SSR mode, the device will continue to log data as well as act as a Repeater for other end units in the network and thereby help to create the mesh network. If the logger was in Run mode prior to switching to SSR mode, then it will continue to run after moving to SSR mode.
Note that in SSR mode the logger still has the same range spec as in Logger mode.
