LI-COR DAqM Quick Start Manual

Data Acquisition Module
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.

Manual tenance instructions for the data acquisition system.
What's what
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.
