Section 2: Datalogger Operation
2.1 Installation
To install the Q-DL-2100 datalogger unpack the datalogger and follow these steps.
1. Configure the QILogger.ini located on the external SD card as appropriate and as
described in detail in Section 2.2 below. This file can be edited via a simple word processor
such as Wordpad or Notepad on a Microsoft Windows based PC.
2. Provide power to the datalogger via the Power Jack on the front panel. One may utilize
nominal 12V DC power supplied from an AC adapter or from a battery source.
3. Switch on the datalogger.
- The dataloggerʼs heartbeat LED should first flash at a cadence of several flashes per
second for nominally 5 seconds. Then the datalogger firmware will configure the
datalogger using INI parameters as found in the QILogger.ini file located on the external
SD card. Next, the datalogger will execute a self test of the data acquisition system,
after which time the heartbeat LED will begin flashing at a cadence of approximately once
every 8 seconds.
2.2 Data Logger Configuration
The Q-DL-2100 datalogger is configured for operation via a set of simple INI parameters.
At power on, the datalogger attempts to read and load these parameter settings from a
QILogger.ini text file located on the external SD card. If the QILogger.ini file is present then
parameter settings are obtained from the file and the file is copied to the internal SD card. If
the QILogger.ini file is not present on the external SD card, then the datalogger will attempt to
read and load parameter settings from the current version of the QILogger.ini text file located
on the internal SD card. If no QILogger.ini file is found on either the external or internal SD
cards, then the datalogger will utilize default values for the INI parameters.
The INI parameters will be described in detail below.
The dataloggerʼs INI parameters may be changed or edited in several ways:
1. via direct editing of the INI parameter fields in the QILogger.ini text file located on the
user-removable Secure Digital (SD) card
2. by setting of the INI parameter fields through a simple Terminal interface program
such as Windows Hyperterminal or Tera Term Pro.
3. by remote telemetry, via email or text message depending on the telemetry option
