6.2.5 Map Descriptor Example 1 - Explicit Configuration using Network Management Polls
The Map Descriptor pollTemp_p shows the use of SNVT_Units for Scaling when polling temperature
The Map Descriptor pollSwitch shows the use of SNVT_Option for Selective data scanning. This only brings in the “State” portion of SNVT_Switch
