X2 Radio Cellular Data Logger
User Guide NEXSENS X2 Radio Cellular Data Logger

Figure 1: X2 Environmental Data Logger

Overview

The X2 with radio to cellular telemetry includes an integrated radio and cellular module.
Three sensor ports provide industry standard protocols including SDI-12, RS-232, and RS-485.
The center port offers direct communication (serial to PC) and power input. Smartphones and tablets connect via WiFi.
Data is accessed and stored on the WQData LIVE web data center. An easy-to-use dashboard and built-in sensor library automatically facilitate setup and configuration.

What’s Included?

(1) X2 data logger
(1) X2 grounding kit
(3) Sensor port plugs, spare O-rings
(1) Power port plug, spare oring| (1) Oring grease
(1) Screwdriver with magnetic tip
(2) Antennas with one-angle adapter
(1) Quick start guide

To get started:
a. Go to WQDataLIVE.com
b. Create a new account or sign into an existing account.
c. Choose or create the project that will contain the data logger by selecting the Projects link from the bottom right footer of the page.
d. Open the project and go to the ADMIN tab located at the top of the project dashboard and click Settings.
From there, choose the Project/Site pull-down menu and select the site for the new data logger.
a. If a site has not been created, select New Site.
Create and save the site before entering the claim code.
Enter the claim code listed below into the space provided under Assigned Devices.
Click Add Device.
a. The new device should be visible in the Assigned Devices list.
If cellular service is not purchased through NexSens, visit the article link below for steps on how to set up the cell modem.

Rotate both antennas clockwise onto their respective connectors following the image below.
Figure 2: Step 6 – Antenna connections.
Use the CONNECT software to ensure the proper cripts are enabled for each sensor on the base and field radio nodes.
a. For each logger, only the scripts for sensors connected to that data logger are necessary.
Follow the link below to enable sensor scripts.
b. nexsens.com/conncss
Remove one blank sensor plug from an 8-pin port (i.e., P0, P1, or P2) for each sensor.
a. Connect all sensors to the desired ports.
Note: Ensure that all SDI-12 and RS-485 sensors have unique addresses.
Connect power (5 to 24VDC) to the center port (6 pins) on the base and all field radio nodes.
Figure 3: Steps 8 & 9 – Sensor and power connection.
Wait up to 60 seconds for the system to check cellular coverage.
a. If the blue LED repeatedly blinks three times, the cellular strength is sufficient to connect the X2 with WQData LIVE.
b. If the blue LED repeatedly blinks once, cell coverage is low. Move the X2 to a location with better cell coverage and cycle power.
c. Ensure all field radios are within line of sight with the cellular base at its final deployment location.
After 20 minutes, refresh WQData Live and confirm all sensor parameters are shown and valid sensor readings appear.
a. The blue LED will be on (solid) when the setup is complete.

Red| Significant system error²| N/A| N/A| N/A| N/A

¹WQData LIVE setup is automatically done after sensor detection.
¹System errors can result from internal sensors detecting high current, humidity, or pressure. These errors can be indicative of a leak or other major problem with the system that requires attention.
