Data Nodes with Battery Power Only
IMPORTANT: If a data node will not have access to a wall
outlet when deployed, make sure you install batteries first.
Data nodes that are initially powered using batteries will not
have routing capabilities.
1. Insert 3 AAA batteries.
LED Indications: Both GREEN and RED LEDs will flash
for 5 seconds, then the RED LED will flash for 5
seconds, and then both LEDs will be OFF.
Verify Power Source in HOBOnode Manager
When you add a data node to the network and it appears in the
Device Table in HOBOnode Manager, verify that the icon in the
Type column indicates the correct data node type: router/data
node, or data node.
Router/Data
Node
Data node can route data from other data
nodes.
IMPORTANT: If a data node appears as a
router/data node but is not plugged into a
wall outlet when deployed, the batteries
will be drained very quickly. See Switching
from AC Power to Battery Power in the
HOBOware Help for information.
Data Node Data node cannot route data from other
data nodes.
IMPORTANT: If this data node is actually
plugged into wall outlet and intended to be
a router/data node, you may have
installed batteries before plugging it into
the wall. See Switching from Battery
Power to AC Power in the HOBOware Help
for information.
