NexSens X2-SDL User manual

X2-SDL Submersible Data Logger Quick Start Guide

The NexSens X2-SDL Submersible Data Logger is a rugged, self-powered remote data

logging system for deploying environmental sensors in lakes, streams, rivers, wetlands,

coastal waters, sewers, and culverts without fear of accidental flooding.

The system is configured with three sensor ports for connection to industry-standard

digital interfaces including RS-232, RS-485 and SDI-12. Power comes from (16) internal

D-cell alkaline batteries.

Unlike many data loggers, the X2-SDL is truly submersible. The housing and battery

compartment are completely sealed and waterproof.

Apply Power

Accessing the battery compartment

The battery lid is designed to be watertight at depths to 200 feet. Tight O-ring seals are

required to maintain this pressure rating and may make lid removal difficult.

The lid removal tool (3/16” handled Allen wrench) supplied in the X2-SDL maintenance kit

can be used for additional leverage when unthreading the battery lid from the

communication bulkhead.

Important: Only remove the white top from the X2-SDL as opening the unit will expose

sensitive electronics which could be damaged in the process.

DO NOT open the unit here

Apply Power

Installing batteries

Once the lid has been removed, the batteries can be installed.

Note: Listen for a single audible beep to indicate the system has properly powered up.

Configure Telemetry

Most cellular and iridium systems will be pre-configured for plug-and-play transmissions to WQData LIVE. Wi-Fi and user-configured data accounts will

require set up.

Direct Connect –Establish permanent wireless data transmission for standard X2-SDLs.

Wireless Network Setup process

Cellular- a 4G Compliant Mini-SIM card is required for installation on cellular models of the X2-SDL. 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.

Iridium Setup process

Connect Sensors

All sensors connected to an X2-SDL must have a NexSens factory installed UW plug connector. Refer to the NexSens sensor listing at

https://www.nexsens.com/support/product-manuals to verify if special setup is required prior to integration with an X2-SDL.

Connect all desired sensors to the X2-SDL via any combination of the three available sensor ports after removing the pre-installed blank plugs.

Important: Record the port number (P0, P1, or P2) occupied by each sensor. 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-SDL, disconnect and re-apply power to the X2-SDL.

Following the power-up beep, 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
