All Node Loggers in the network will have the same reading interval and
synchronized clocks. All Node Loggers will simultaneously read their sensors when
scheduled to take a reading and will transmit their data to the Hub RTU over the next
1 to 2 minutes. The Node Logger clocks will be updated and any change in reading
interval will be implemented as they transmit their data.
The Hub Logger (often a Campbell Scientific data logger) will request data from the
Hub RTU once the Hub RTU has finished receiving data from the Node Loggers.

ATTERY
3.6 V lithium-thionyl chloride batteries are recommended for use with any data
logger. Standard batteries (defined as SAFT LSH 20 D-cell, or equivalent) are used
for any logger with a wireless option (DT Link or RSTAR). Wireless connections will
not work with other lower current batteries.
More information regarding batteries and battery life can be found in the instruction
manuals for individual data loggers and in the DT Logger Host instruction manual
(ELM0080).
