1. General

X2-SDL Body Tag Identification

Each X2-SDL and SDL-V2 data logger has a body tag number for identification. The long

housing tube has the tag etched between the antenna and sensor bulkheads.

The default name of the device on WQData LIVE will incorporate this number (see Figure

3). NexSens technical support specialists will typically request the body tag for remote

troubleshooting or if NexSens-supplied data services require activation or cancellation.

Figure 1: X2-SDL body tag location on the long enclosure tube opposite the NexSens logo.

Figure 2: Example body tag marking 1715.

Figure 3: X2-SDL default

device name. Note all

SDLs will have a ‘3’

entered in front of the

Body Tag number.

What depth of submersion is the X2-SDL rated for?

The X2-SDL is rated for submersion up to 200ft (~60m) depth.

Note that the SDL-CAP accessory is required to fully submerge cellular or radio models

containing an external antenna. The antenna port of Wi-Fi only models is epoxied closed

and may be completely submerged using the standard battery lid.

2. System Power

What type of batteries does the X2-SDL take?

The X2-SDL requires (16) D-Cell Duracell1 Alkaline batteries.

1D-cell batteries from other manufacturers may have sub-flush negative terminals which

can result in poor contact and may affect the consistency of power supplied to the X2-SDL

logger.

Apply Power to the X2-SDL

The X2-SDL has flexible power input choices that provide several options in terms of type

and number of power sources.

Basic Requirements

5-24 VDC [+/-10%] (Reverse polarity protected)

Current Draw (Typical @ 12VDC): Low power sleep: 350uA; Logger Active: 35mA; Wi-Fi

Transmitting: 43mA; Cellular Transmitting: 300mA

Peak Current: 500mA @ 12V for 1 second

Input Channels

The X2-SDL data logger is equipped with two separate power input channels. The logger

pulls power from the highest priority channel that has a voltage within the specified range.

If one of the sources falls outside the range, the next highest priority channel will

automatically take over without an interruption in supply.

From highest to lowest priority, the channel order is as follows.

Primary

Backup

This multi-input design allows users to connect redundant power sources in order to

mitigate the likelihood of system power loss.

Typical Application

Figure 1: X2-SDL Data

Logger.

Frequently, X2-SDL systems receive power from (16) internal D-Cell Alkaline batteries. The

following article describes the process for installing these batteries properly before

deployment.

Connector Wiring

Power may be applied to the X2-SDL via the UW-6 receptacle port by a UW-USB-485P for

connection to a PC, or from a customized solar power kit. Most applications, however, rely

on the internal D-Cell Alkaline batteries during deployment.

Numbering.

Install Batteries in the X2-SDL Data Logger

The battery compartment of the X2-SDL data logger accommodates (16) D-Cell Alkaline

batteries for system power. These batteries should be replaced once the reported

secondary power falls to 8V to avoid data collection interruption.

1. Locate the white battery lid at the top of the X2-SDL.

2. Rotate the lid counter-clockwise to remove it.

a. Note: Due to the double O-ring lid seal, this will take significant effort to loosen.

b. The 3/16″ ball-point hex driver included in the X2-SDL maintenance kit can be

inserted into either of the two recesses in the lid to provide extra leverage.
