Automatic Recording with
WiFi™
Connection (
“W”
model only)
The
NSRTW_mk3
supports a mode of operation where it periodically connects to a server (a Windows
PC running the
Instrument_Listener
application) through
WiFi™, or Convergence Instrument’s cloud
solution
. This feature is designed to let the instrument record autonomously, periodically report the
levels recorded since the last connection, and optionally send emails with noise-level or low-battery
alerts. When set, this feature will work, even if the instrument is reset, or if it loses and regains battery
power (for instance if the instrument is reconnected to a charger after the battery has been completely
drained).
This PC-server being connected-to does not have to be in the vicinity of the instrument. It can be a
continent apart, as long as it is reachable through the internet, and all firewalls have been set to allow
the connection.
The instrument connects to a
WiFi™
Router or
Access Point
that is in its vicinity. From there, it will find
the server to connect to, either by its IP address, or by its domain name.

Connectivity
6.7.1.1
WiFi™
Reporting Without Cloud Service
Note:
When using the instrument with WiFi™ connectivity, do not start a recording manually, or via
the timer. The instrument will be completely controlled by the server, including starting the recording,
erasing memory if required, and resetting the time.
When using the
WiFi™
feature, the instrument will try to connect to a known server at regular intervals,
or immediately in case of alarm.
Whenever it connects, the instrument will talk to a special
Instrument_Listener
application running on
the server. That application will do the following:
•
If the instrument was recording:
o
Upload the latest recorded data from the instrument and updates a growing file with
that data (create the file if it was not already created).
•
If the instrument was not recording (for instance if the recording was stopped earlier because
the memory was full):
o
Upload the latest recorded data from the instrument (if any) and update the recording
file.
o
Adjust the instrument time (does not adjust the time zone of the instrument, just
precisely readjust the Universal-Time-Code running in the instrument).
o
Delete all data in the instrument’s memory (all that data has already been safely
stored in the recording file on the server).
o
Start a new recording.
6.7.1.2
Email Alarms
In addition to trying to connect to the server at regular intervals, the instrument will try to connect
immediately to the email server in case of alarm. The alarm function does not require the use of a
server or
Listener
application. The instrument will typically connect to an email server, such as a
gmail
account.
