About DAQLog
DAQLog is a configuration and data logging application developed for use with Measurement Computing’s LGR5320 Series of data acquisition and logging devices.
With DAQLog software and a LGR -5320 Series device, you can perform the following operations:
Create logger settings files for ac quiring and logging analog, digital, and counter data from LGR-5320 Series
devices. Settings files can include analog and digital triggers, event logging, counter debounce filters, and pacer
output.
Store logger settings files in dedicated folders for deployment, modification, and reuse.
Deploy logger settings directly to logger devices over a USB connection, or remotely through Secure Digital
(SD) and Secure Digital High Capacity (SDHC) cards.
Retrieve binary data and event files stored on SD/SDHC cards and convert them to comma-separated values
(.csv) files.
Easily navigate to stored settings, data, .csv, and event fi les.

You can insta ll this DAQLog software package on a computer running one of these ope rating syst ems:
Windows XP with Service Pack 2 (SP2)
Windows VISTA (32- and 64-bits*)
Windows 7(32- and 64-bits*)
* Application is 32-bits, but software does include 64-bit drivers for accessing the device.

Getting Started
This chapter explains how to:
install the DAQLog software
install and prepare your LGR-5320 Series device to log data using DAQLog
where to insert your SD card
how to run DAQLog
Install DAQLog
Install DAQLog software before you install your device(s).
1. Insert the DAQLog CD in your CD drive and wait for the installation program to start.
If the installation program does not start automatically, use Windows Explorer to browse to the root o f the CD,
and double-click on
2. Follow the on-screen instructi ons to install the software.
Install your DAQLog device
Install.exe.
Chapter 2
If you are installing the device on your computer, refer to the LGR-5320 Series device’s user’s guide for installation
instructions.
Connect signals to your LGR-5320 Series device
Once your device is powered, connect your LGR-5320 Series device to the sources and grounds of t he analog,
counter, and digital data you want to acquire and log.
Refer to the screw terminal pinout tables in your LGR-5320 Series device’s user’s guide.
Insert the SD card
If your device is installed remotely from your computer, you need an SD card reader to transfer configuration and
data files between the device and your computer.
Otherwise, you can use your LGR-5320 Series device as an SD card reader over a USB connection.
For the logging exercise presented later in this guide, please remove any other SD, SDHC, or flash drives installed
in your computer.
Run DAQLog
Now that you installed the DAQLog software, and connected your DAQLog device to its data source(s), you can
start logging data using DAQLog.
Run DAQLog by selecting
Programs Measurement Computing DAQLog DAQLog from t he Start menu.
The main DAQLog window opens. This window is explained in more detail in the next chap te r .

Working with Settings Files and Folder Locations
You can configure a LGR-5320 Series device using settings (.set) files created with DAQLog.
A settings file contains parameter settings that determine:
the type of data the device logs (analog, digital, counter, event)
the source(s) of data (channels, ports), along with how those sources are configured (single-ended, differential)
how much data to log, and when a logging operation starts and stops (triggers, sampling rate, number of
samples)
the management of data files (folder structure, file naming conventions, and so on)
Settings files can be stored and deployed from your computer or from an SD card. You can create locations whose
main purpose is to store these types of files.
Adding a settings folder location
To add a new or existing folder loca tion to store settings files (.set), do the following:
1. Click the
Right-mouse click method

DAQLog Software User's Guide Working with Settings Files and Folder Locations
o Counter: Use this mode for high-speed pulse and general counter operations. You can use the Index input
to clear, gate, latch, or decrement the counter.
Up/Down Counter: In this mode, phase A is the pulse source and phase B is the direction. The counter
o
changes direction depending on the state of phase B. The Phase B Edge setting determines whether a high
or low signal at phase B causes the counter to count up.
Encoder: Measure the system position (counts), velocity (counts per second), and direction of rotation.
o
This mode supports encoders with X1, X2, and X4 count modes.
Period: Measure the period of a signal at a counter channel's phase A input. You can measure x1, x10,
o
x100 or x1000 periods.
PulseWidth: Measure either the time from the rising edge to the falling edge, or the time from the falling
o
edge to the r ising edge o n a counter channel's pha se A input.
Timing: Measure the time between the rising or falling edge on the phase A input and the rising or falling
o
edge of the Index channel. The edges used are determined by the Phase A Edge and Index Edge options
settings.
Refer to the “Screw terminal pin out” section in the “Specifications” chapter of your LGR-5320 Series device
user’s guide for your de vi ce’s counte r signal pin out.
Option: Depending on the Mode selected, you can set these counter options:
Counter and Up/Down Counter mode options
TotalizeThe counter c ounts rising edges or fa lling edges.
o
Clear On Read: The counter is cleared after each synchronous read. The counter value is latched and
o
returned before it clears.
Encoder mode options
1X: Counts rising or falling edges on phase A, depending on the phase A Edge setting (Encoder mode
o
only).
2X: Counts rising edges and falling ed ges on phase A.
o
4X: Counts rising edges and falling ed ges on phase A and phase B.
o
Period mode options
1 Period: The measurement latches after one complete period is observed
o
10 Period:The measurement latches after 10 complete periods are observed .
o
100 Period:The measurement latches after 100 complete periods are observed.
o
1000 Period:The measurement latches after 1000 complete periods are observed.
o
Tick Size: For Period, PulseWidth and Timing modes, you can set the counter tick size measurements. The
system clock of the field programmable gate array (FPGA) is 20 ns.

Debounce Mode: Select one of these debounce mode options:
AfterStable: Rejects glitches and only changes state after a specified period of stability (set with the
o
Debounce Time parameter).
Use this mode with electro-mechanical devices like encoders and mechanical switches to reject switch
bounce and disturbance s due to a vibrating encoder that is not otherwise moving. Set the debounce time
short enough to accept the input pulse you want, but longer than the period of the disturbance.

stability (
Debounce Time) passes.
Use this mode when the i nput signal has groups of glitches, and you want each group to be counted as one.
This mode r ecognizes and count the fi rst glitch within a group, but rejects the subsequent glitches within
the group if the debounce time is set accordingly. Set the debounce time to encompass one entire group of
glitches.
Debounce Time: Select from 16 programmable debounce times in the range of 0.5 µs (500 ns) to 25.5 ms.

Working with Data Folder Locations, Data Files, and Converted Data Files
LGR-5320 Series devices use data (.dat) and event (.evt) files to store the data and record events during a logger
session.
A data file is a binary file that contains data from a logging sessio n. Data files can be stored on your computer and
on an SD card.
You can also create locations whose main purpose is to store converted data files.
You can convert these binary data files to a comma separated value (csv) file that you can view in a spreadsheet
application.
An event file logs event s based on the c onfiguration of a logging session.
