Logger Server Name (LNS)
As the logger IP address may be unpredictably changing (this is known as “dynamic IP”),
Kintech Engineering has developed the necessary infrastructure to let Atlas get the
logger IP address from a server on the internet. We have named it “Logger Server Name”,
LNS. This LNS server holds in a table the current IP address of every ONLINE logger.
When the Orbit 360 data-logger connects to the APN and receives an IP address, the
logger shows INET in the upper right corner of the display. Then the logger initiates a
connection to the LNS to update its IP address in the table. After that, the INET sign turns
into ONLINE, indicating that the logger is ready for incoming connections from Atlas.
When Atlas wants to connect to a particular logger, it firstly asks to the LNS what the IP
of that particular logger is (of that serial number).

Unfortunately, not all GSM lines and GSM operators allow the reception of incoming
connections from the internet. In other words, they do not allow devices connected to
internet through their APN to work as a server. In such conditions, the assigned IP
