LI-COR DAqM Manuel utilisateur

Data Acquisition Module Quick Start Guide

The Data Acquisition Module (DAqM) is used to collect biomet data in LI-COR eddy covariance systems. This document introduces the DAqM and describes how

to connect it to a SmartFlux 2 or 3 System for the first time.

Switchable Power OutputsDigital Input/Output Terminals

Analog input terminals: Connections for analog sensors.

Ground lug: Connect to an earth ground for lightning protection.

SDI-12 terminals: Connections for SDI-12 sensors. Terminal blocks (not

shown) are used to connect multiple SDI-12 sensors.

12 VDC Output: Regulated power supply for sensors.

Switched power outputs with current sensing: Switchable power outputs

with current sensing for powered sensors.

Digital input/output terminals: Connections for digital sensors.

DATA IN: Used to connect additional DAqMs.

Power input: Power to the DAqM (+9 to 30 VDC).

DATA OUT: Connects to the SmartFlux 2 or 3 System, to a Data Retention Module, or to another DAqM if the system has more than one.

Getting Started

Follow these steps if you have a DAqM without a DRM. If you have a DRM, follow the steps on the DRM quick start guide.

Step 1: Install the Blueprint Utility

Go to www.licor.com/env/support/Biomet-System/software.html. Choose the software for your operating system, install it, and open the app.

Step 2: Load a biomet program

Click Biomet Library, select the program that corresponds with your sensor package. Enter the calibration information for your sensors. The program will tell you

which multipliers are needed. For custom programs, you can either modify an existing program or create one from scratch. Click Help for in-app assistance.

Bundles of wire leads connect the DAqM to the SmartFlux 2 or

3 System. A standard Ethernet cable connects the SmartFlux

System to your network or computer. A detailed wiring dia-

gram is provided in the Data Acquisition System instruction

manual.

Step 4: Power on the system

Each part needs to be powered on (+9 to 30 VDC).

Step 5: Connect and send the program

Click Connect in the Blueprint Utility. Select the SmartFlux Sys-

tem from the list. It is identified by the serial number. Click

Configure Port and select the port that the DAqM is con-

nected to. Click OK to connect. Click Push to load the program. Additional steps must be taken to configure SDI-12 sensors and to connect the DAqM to your
