Configure Telemetry
Most cellular and iridium systems will be pre-configured by NexSens for plug-and-play transmissions to WQData LIVE. Wi-Fi and user-configured data
accounts may require set up.
Direct Connect –Establish permanent wireless data transmission for standard X2s.
Wireless Network Setup process
Cellular- a 4G Compliant Mini-SIM card is required for installation on cellular models of the X2. Factory-installation is recommended, but user installation is
possible.
SIM Installation process
Configure Network APN
Iridium- Factory-installed Iridium satellite modems allow for communication in the most remote deployment locations.

Connect Sensors
All sensor cabling connected to the X2 must be configured with one of the following:
•NexSens factory installed UW plug connector.
•NexSens UW-FWP series field wireable plug.
Refer to the NexSens sensor listing at https://www.nexsens.com/support/product-manuals for sensor-specific wiring and configuration information prior to
integration with an X2 system.

Connect Sensors
Connect the antenna, power and sensors to the X2
1Connect the system antenna (if equipped) and move into an area
with strong signal coverage.
Remove the center power plug and required outer port plugs (1
for each sensor to connect)
Connect sensors to any outer port (8 pin). *Record the port
number (P0, P1, or P2) occupied by each sensor.
Connect power (5 to 24VDC) to the center port (6 pin)

*After the initial setup, sensors must always be reconnected to the same port for proper communication.

Sensor Auto-Detection
Following the configuration of the logger telemetry (if required) and the connection of all sensors to the X2, disconnect and re-apply power to the X2.
Following power-up, the logger will automatically begin to scan through a list of common sensors to build the deployment sensor list. Sensors discovered during
this process will automatically be updated on WQData LIVE via the X2’s on-board telemetry.
Sensor detection will take approximately 10 minutes. Leave the full system connected and powered while proceeding through the WQData LIVE setup. Following
detection, sensor readings will be logged and uploaded at a 10-minute interval until adjusted by the user.

WQData LIVE Overview
WQData LIVE is a Cloud Data Center used in conjunction with the X2 data logger line for the following functionality:
Data Collection- automatic X2 data upload to the web
Data Export
Remote System Configuration
9

WQData LIVE Setup
To begin accessing sensor data from the X2 logger online, proceed through the following walkthrough:
https://www.nexsens.com/pdf/WQData-Live-Getting-Started.pdf
The guide covers the three main prerequisites for setting up the Data Center:
-Creating a free WQData LIVE account
-Creating a new project on the WQData LIVE Datacenter
-Using the Claim Code provided with each X2 to add the logger profile to the project
10

Review X2 Project Configuration
Once the logger has been claimed into the project and it is visible on WQData LIVE, check the ‘Last Contact’ time located in the lower right corner of the Project
Dashboard page. The last successful data transmission from the X2 is denoted by this parameter.
Provided more than 10 minutes has elapsed since the last power cycle, the parameter lists from the detected sensors as well as the logger’s internal diagnostic
parameter set (shown below) will automatically be updated.
11

Customize Logger Settings
Adjustments to the X2 such as those listed below can be made remotely from the Remote Device Configuration Menu on WQData LIVE.
-Change Data Upload/Transmit Frequency
-Change Individual Sensor Logging Intervals
-Set offsets for parameters
-Queue additional Sensor Detections if new instrumentation has been connected to the system

Generate/Review Reports
CSV or PDF Reports can be manually generated, or configured to send automatically on a user-defined schedule from WQData LIVE.
Information on the Report tool for the WQData LIVE datacenter can be found here.
