1. INTRODUCTION
The Model LC-2x16 16 Channel Datalogger is a low cost, battery powered and easy to use
measurement instrument designed to read up to 16 vibrating wire sensors equipped with
thermistors.
The 320K standard memory provides storage for 3555 data arrays. Each array consists of an
optional datalogger ID string (16 characters maximum), a timestamp consisting of the year, date
(Julian day or month/day format), time (hhmm or hours/minutes format) and seconds when the
reading was taken. Also included in the data is the internal 3V (or external 12V) battery voltage,
the datalogger temperature, the vibrating wire readings, the transducer temperature and the Array
number.
Internal math is calculated using 32 bit floating point notation (IEEE). Math operations on the
instrument readings, such as application of zero readings, gage factors (or calibration factors)
and offsets when using a linear conversion technique or polynomial coefficients when using the
polynomial conversion, provide outputs directly in engineering units. The dataloggers internal
configuration is defined through communication with a computer using the supplied RS-232 or
USB (or optional RS-485) interface cable. The datalogger is configured and monitored using
LogView, a Geokon proprietary Graphic User Interface (GUI) software application (See Section
2.3).The datalogger can also be configured and monitored via text-based commands with any
standard terminal emulator software, such as Microsoft Windows HyperTerminal™(see Section
3, Command Set ).
The following three communications options are available for the LC-2x16:
LC-2x16 Model # Communication
8002-16-1 RS-232
8002-16-2 USB
8002-16-3 RS-485
8002-16-1: Communication with the LC-2x16 is implemented via the host computer’s RS-
232 COM port. See Section 2.3.6 for further information.
8002-16-2: Communication with the LC-2x16 is implemented via the host computer’s USB
2.0 port. When connected to a computer via the USB port, the LC-2x16 appears to
the computer as a “virtual” COM port. The LC-2x16 datalogger also receives all
of its operating power from the computer, thus extending the internal 3V (or
external 12V) battery life. When disconnected from the USB port, the datalogger
automatically switches to the internal 3V (or external 12V) battery pack. See
Section 2.3.7 for further information.
8002-16-3: Communication with the LC-2x16 is implemented via RS-485. This allows for
long communication cables (up to 4000’) between the host computer and the LC-
2x16. The ability to network two or more LC-2x16 dataloggers together is also
available with this communication option. See Section 2.3.8 and Appendix F,
Networking, for further information.
2
All data, both readings and configuration, are stored in nonvolatile EEPROM with a typical
storage life of 10 years (minimum). The internal temperature compensated real-time clock, used
to provide timekeeping and triggering of readings, is accurate to ± 2 minutes/year.
The comma delineated ASCII output format allows for easy importing into popular spreadsheet
programs such as Lotus 1-2-3or Microsoft Excel. See Appendix D for sample data files.

Insert four D-cells straight down into the battery holders. Ensure the polarity of the batteries
matches the diagram on the battery holder. Note that there is a zip-lock bag containing four
desiccant packs shipped along with the batteries. As soon as the batteries are installed, take the
desiccant packs out of the zip-lock bag and place them inside the enclosure. Immediately close
and reseal the lid. This will help to prevent condensation of moisture within the enclosure. If
batteries and desiccants are installed in the office, be sure to seal the lid before going out to the
field.
2.2 Earth Ground Installation
The LC-2x16 provides lightning protection in the form of gas tube surge arrestors. In order for
these components to divert the energy from a lightning strike safely to ground, a good solid
electrical connection to earth ground needs to be made. A grounding rod should be driven (or
other suitable attachment to earth utilized) to ground the system and provide a path to earth in the
event of a lightning strike. A 6' to 8' copper stake with appropriate large gauge wire (12 AWG or
larger) connected to the LC-2x16 enclosure is suggested. The stake should be driven as close to
the datalogger as possible, and to a depth of at least three feet (one meter). A copper grounding
lug is supplied on the exterior of the LC-2x16 enclosure to provide connection to this wire from
the grounding rod.
6
2.3 Software Installation and Setup
LogView is Graphical User Interface (GUI) software is used to communicate with the datalogger
using a personal computer running a Microsoft Windows® operating system. Other general
purpose communication programs (i.e. Windows HyperTerminal™) can also be used to
communicate with the Model LC-2x16 via text-based commands. LogView and the USB drivers
install program can be downloaded at www.geokon.com/software.
Perform the following steps to install LogView software for each computer that will connect to
an LC-2x16. These instructions are for computers running Windows XP. The installation
procedure is very similar for computers running Windows 7, Windows 2000 and Windows 98.
This installation procedure needs to be performed just once for each computer that will run
LogView to communicate with a LC-2x16 datalogger.
NOTE: The USB drivers are only required for LC-2x16 models 8002-16-2 and the 8002-5 RS-
485 Interface
Make sure that the (4) 1.5V D-cell alkaline batteries are installed in the datalogger (See Section
4.2 for instructions) and that the LC-2x16 datalogger is not connected to the computer at this
time.
2.3.1 LogView Installation:
1. Using Windows Explorer, navigate to the extracted downloaded files and double click
on the file “start.bat” to start the install process.
2. Click “Next >” when the Welcome window appears.
3. When the Choose Install Location window appears, choose a folder for the LogView
installation then click “Next>”.
4. When the Choose Start Menu Folder window appears, choose an appropriate folder
(default is Geokon) then click “Install”.
5. Click “Next >” when the Java Installation Complete window appears.
6. Click “Finish” when the Completing the LogView Setup Wizard window appears.
7
2.3.2 Launching LogView:
Launching LogView can be accomplished two different ways. Double clicking on the
desktop icon:
Or via the Windows Start button: “Programs →Geokon →LogView”
2.3.3 LogView Workspaces:
When opening LogView for the first time, the user will be prompted to create a
workspace name (see Figure 2). The workspace name can be any combination of letters
and numbers and, ideally, will be descriptive in nature. See the LogView User’s Guide
for more information on workspaces.
Figure 2 - Select Workspace Name
Once the workspace name has been selected, clicking on “Ok” causes LogView to
prompt the user to choose or create a folder where all the workspace elements will be
stored (see Figure 3). The folder location may be entered directly, i.e.,
C:\Workspaces\East Coast or the Browse button may be used to navigate to a folder
location or to create a new folder (see Figure 3). This workspace location will be stored
in the LogView configuration for subsequent application access. Once workspaces are
created, future user access is always by name.
8
Figure 3 - Select Workspace Folder
If no other is specified, a default folder path is displayed based on the system default
workspace path combined with the new workspace name. After the folder path has been
specified, either the default or user selected (see Figure 3), clicking on “Ok” will display
the main window of LogView (see Figure 4). On the left-hand side of the main window is
the Project Explorer displaying the newly created workspace. The user can now add new
project(s), datalogger(s) and sensor configurations to the workspace by right-clicking on
the workspace and using the menu tools.
Figure 4 - LogView Main Window

2.3.4 Adding Projects to LogView Workspaces:
Right-clicking on the “PRODUCTION” workspace brings up a context sensitive menu
that allows the user to add projects to this workspace (using the “New→Project” menu
selection). Select a name that makes sense for the real world project this program will be
used for. In this example “TestLoggers” was chosen as the project name (see Figure 5
below).

2.3.5 Adding Dataloggers to LogView Projects:
Right-clicking on the “TestLoggers” project brings up a context sensitive menu (see
Figure 6) that allows users to add dataloggers to their projects. Selecting New→Logger
from the context menu causes the “Datalogger Settings” dialog to be displayed. Like
Workspaces and Projects, Dataloggers can be assigned a unique name. For this example,
“MyLogger” was chosen for the Datalogger name. For a complete description of all
datalogger settings please see the LogView Online Help section on Datalogger Settings.
For connection purposes, the relevant tab in this dialog is “Connection Options” (see
Figure 7).

After physically connecting to a PC, all LC-2x16 dataloggers require a COM port to be
identified in the “Connection Options”. Starting with firmware revision 3.1.X, LC-2x16
dataloggers can communicate at baud rates of 9600 and 115,200. Before this revision the
datalogger baud rate was 9600 only so, for these dataloggers, the default setting should not
be changed (see Figure 7).

2.3.6 LC-2x16 Connection (8002-16-1, RS-232):
Connect the supplied LC-2x16 RS-232 Communications cable (S-8001-6) to the COM
port of the LC-2x16 datalogger. The protective cap on the datalogger COM connector is
removed by pushing in and turning. Plug the DB-9 end of the RS-232 Communications
cable into the host computer’s RS-232 port (either internal or external via a USB to Serial
converter). Proceed to Section 2.3.9, Connecting to a Datalogger with LogView.
2.3.7 LC-2x16 Connection (8002-16-2, USB) :
Connect the supplied LC-2x16 USB Communications cable (COM-109) to the USB port
of the LC-2 datalogger. The protective cap on the datalogger USB connector is removed
by pushing in and turning. Plug the USB-A end of the USB cable into an available USB-
2.0 port on the host computer.
NOTE: On certain PCs with operating systems older than XP, Service Pack 3, the 8002-
16-2 may require the installation of a driver to properly communicate with the PC. If the
PC does not recognize the datalogger’s internal USB to serial converter then the driver
may need to be installed by executing the program, CDMv2_xxxx, from the LogView
Install folder. Proceed to Section 2.3.9, Connecting to a Datalogger with LogView.
2.3.8 LC-2x16 Connection 8002-16-3 (RS_485):
Make the COM port connection per Section 2.3.6 (RS-232) or 2.3.7 (USB), and then
refer to Appendix F, Networking, to establish communications.

2.3.9 Connecting to a Datalogger with LogView:
1. With a Datalogger profile configured and selected in the Project Explorer (see Figure
8), click on the “Open Connect” button on the LogView Toolbar.
2. When connecting to a new Datalogger for the first time, the message below (see
Figure 9) may be displayed after a few seconds. This is normal and is only an
indication that the datalogger doesn’t match the configuration created in the Project
Explorer. Click on “Continue” to finish connecting to the datalogger.
3. Click on the “Upload Settings” button on the LogView Toolbar to synchronize the
datalogger with the LogView configuration (see Figure 10).
4. LogView is now connected and configured correctly for the LC-2x16 datalogger.
Sensors can now be added to the datalogger in a similar fashion as adding Dataloggers
to Projects. Sensor settings are accessed via the context menu from the Project Explorer.
5. Always upload the new settings to the datalogger after changing its configuration in
LogView.

2.3.10 Determining COM Port Numbers:
When connecting an 8002-16-1 datalogger to a PC with an internal serial port(s) the COM
Port number that LogView requires is usually COM1 or COM2 but, occasionally may be
COM3 if the PC has more than one internal serial port. Figure 11 below illustrates that the
PC has two serial ports, one internal (COM1) and the other via a USB to serial converter
(COM13).
Figure 11 - PC Internal COM Port
When connecting an 8002-16-2 datalogger to a PC the COM Port number that LogView
requires can be any number and depends on how many other devices are attached to the PC
like, internal serial ports and Bluetooth devices. Figure 12 below illustrates that the PC has
three serial ports, one internal (COM1) and the other two via USB to serial converters
(COM13 and COM3). One way to determine which COM port an 8002-16-2 datalogger is
attached to is to disconnect the cable and see which COM device disappears from the
Device Manager Ports list.
Figure 12 - USB to Serial Converter COM Ports
In this case, COM3 is actually the 8002-16-2 datalogger and not a universally available serial
port.

2.4 Communication Setup Example Using HyperTerminal
NOTE: If using a 8002-16-2 USB LC-2x16, it is important that the LC-2x16 first be connected
to the computer’s USB port before attempting to communicate so that the LC-2x16 can be
recognized by the computer as a virtual COM port.
Proceed with the following steps to connect with the datalogger using a terminal emulator
program such as Microsoft Windows HyperTerminal™.
1. Launch HyperTerminal (Start →All Programs →Accessories →Communications →HyperTerminal).
2. Enter a name for the New Connection and click OK (see Figure 13):
Figure 13 - HyperTerminal Connection Description
3. In the Connect Using window, select the appropriate COM port (see Figure 14):
