1 INTRODUCTION
The following guide provides a high-level overview for setting up a MEMS Digital In-
Place Inclinometer System (IPI) system. Please consult the MEMS Digital In-Place
Inclinometer System Installation Manual (ICM0062) and the DT Logger Host
Instruction Manual (ELM0080) for detailed instructions not covered in this guide.
2 HARDWARE SET UP
To ensure that all components are working together correctly and able to
communicate, RST recommends that initial set up and configuration take place in the
office or warehouse, prior to final installation in the field.
2.1 INITIAL SET UP AND CONFIGURATION
1. Connect all IPI sensors in a string by mating the connectors (Figure 2-1).
FIGURE 2-1 MATING THE CONNECTORS
NOTE: IT IS NOT NECESSARY TO CONNECT THE BAY RODS AT THIS POINT,BUT CAN BE
DONE TO ENSURE FAMILIARITY WITH THE CONNECTION PROCEDURE.
NOTE: DO NOT CUT THE CABLE TIE THAT LOCKS THE CABLE TO THE WHEEL
ASSEMBLY (FIGURE 2-2). CABLE TIES HAVE BEEN PLACED TO RELIEVE
TENSION ON THE CABLES.

FIGURE 2-2 CABLE TIE –DO NOT REMOVE
2. Record the serial number of each sensor and its order in the string, from the top
to the bottom of the string.
Connect the IPI string to the desired data logger, following the wiring scheme outlined in
Table 2-1.
CAUTION: IT IS CRITICAL THAT THE SENSORS ARE INSTALLED IN THE SAME ORDER ON
THE STRING AS IN THE INITIAL SET UP AND CONFIGURATION.READ ERRORS
AND STRING FAILURE MAY OCCUR.

3. Follow the instructions outline in Section 4 to configure the string. Ensure that
serial numbers are entered in the same order as they appear on the string.
4. Disconnect all sensors and place the shipping caps on all connectors to prevent
contamination.
2.2 INSTALLATION IN THE FIELD
Once the system and communication have been configured in the office or
warehouse, installation in the field will be straightforward. See ICM0062 for detailed
instructions.
2.2.1 Cleaning Connectors
Keep caps on connectors (Figure 2-3) until mated to the next sensor to prevent
contamination. Store the caps in a clean, dry location for future use.
Any dirt within the connectors may cause water ingress and cause an entire
string of IPIs to fail.
CAUTION: CONTAMINATION,SUCH AS DIRT OR DUST,IN THE CONNECTORS CAN CAUSE
READ FAILURES IN AN ENTIRE STRING OF IPIS.
In the event of contamination within the connectors, the connector ends may be
flushed with isopropyl alcohol and set aside to dry.
CAUTION: IT IS CRITICAL THAT THE SENSORS ARE INSTALLED IN THE SAME ORDER ON
THE STRING AS IN THE INITIAL SET UP AND CONFIGURATION.READ ERRORS
AND SYSTEM FAILURE MAY OCCUR.

4.2 SOFTWARE INSTALLATION
1. Run the software installation file RST_DTLogger_Setup_X.XX.X.exe,
where X.XX.X indicates current software version. The current version can be
downloaded from:
https://rstinstruments.com/resources/software. Navigate to the site and
select the appropriate data logger.
2. Follow the on-screen instructions to install the software. The default directory
is: C:\Program Files (x86)\RST Instruments\DT Logger Host\
Contact RST Instruments with any questions or concerns.
4.3 DATA LOGGER CONFIGURATION
1. Connect the IPI string to the logger by following the wiring scheme outlined in
Table 4-1. Connect the logger to a PC via the USB port or via the wireless
module, if applicable.
NOTE: THE DT LOGGER HOST SOFTWARE REQUIRES A SET OF DRIVERS INSTALLED ON
THE HOST COMPUTER IN ORDER TO COMMUNICATE OVER USB COMMUNICATION
PORT.
IF AUTOMATIC DRIVER UPDATE IS ENABLED AND AN INTERNET CONNECTION IS
AVAILABLE,RST USB DRIVERS WILL BE DOWNLOADED FROM MICROSOFT™
WINDOWS UPDATE SERVER AND INSTALLED AUTOMATICALLY.

2. Launch the software. Once the software connects to the logger, the port and
status indicators will turn green and the Status screen should display logger
information.
3. Navigate to the DTBus tab to configure the IPI sensors (Figure 4-1). All
currently configured sensors are listed along with sensor index, sensor serial
number and sensor type.

c. Click on Add Node to add a new sensor to the string. Ensure the right
sensor type and version have been selected.
d. Click on the Serial column and enter the last 5 digits of the serial
number of the first sensor in the string.
e. Repeat Steps c and d until all sensors in the string have been
entered.
f. Confirm that the serial numbers of the sensors are entered in the
same order they will be installed.
g. Click on Verify Nodes to ensure that each sensor in the string is able
to communicate with the logger.
4. Enable Eng Units to record the data in specific Engineering Units. Enter the
appropriate parameters.
5. Once the desired parameters are set, click the Upload to Logger button to
apply the changes. Click “Yes” when asked to update Modbus Addresses.
6. Wait for update process to finish. The logger is now logging data.
7. If desired, real time sensor readings can be monitored by selecting the
Monitor tab.
NOTE: EXISTING ENTRIES MUST BE CLEARED (NOT RENAMED)BEFORE NEW SENSORS
ARE ADDED TO THE TABLE.
NOTE: IF ENTERED CORRECTLY,THE ORDER THAT THE SENSORS APPEAR IN DT

8. Under the Status tab, check to make sure the parameters are correct and
that the logger is either logging or there is a log pending under the Sampling
section.
9. Click Disconnect button to terminate logger connection.
10. Exit the software and disconnect the communication cable.
11. The data logger should now be taking readings. Return to the logger to
download the data. Check the remaining battery life every time you connect.
The battery state is an approximate value based on recent battery use.
4.4 DOWNLOADING DATA
1. Connect the communication cable to your computer and the DT2485 and
launch the software. If the connection is successful, the port and status
indicators turn green and the Status screen should display logger
information.
2. Press the Collect Data button on the Status tab to download the data. A data
file (*.csv) will automatically be created in the data directory. The default data
directory is:
My Documents\Multichannel\
3. Before downloading, the program will ask whether you would like to erase
the existing data on the logger or keep appending to existing records. To
erase the old data and continue logging with the same parameters, select
the Logging tab and press Apply Settings.
4. To keep the old data on the logger and continue logging, exit the program,
and disconnect the communication cable.
5. To change any logging parameters, do so under the Logging tab and press
Apply Settings to save the changes.
6. Disconnect the communication cable when finished.
4.5 HELP SYSTEM
An extensive help system in DT Logger Host can be activated anytime by pressing
F1 or the RST icon. Answers to common problems and troubleshooting tips can be
found by browsing help topics or searching using keywords.

Before updating the Modbus addresses on the IPI string, ensure that all settings
have been saved on the logger unit.
Modbus addresses for sensors connected to a Campbell CR6 logger can be
updated via a CRBasic code. Once the user has defined the number of sensors
and their respective serial numbers, the code will automatically assign a Modbus
address to each sensor in the string once the code is run.
1. Open LoggerNet.
2. Navigate to the “CRBasic Editor” option under the Program menu (Figure 5-2).

5.3 CR310 WIRING
To connect an IPI system to a CR310 Campbell logger, an RS485 to RS232
interface, such as RST’s ELGL4000 series, will need to be used. The interface/IPI
assembly can be wired as follows (Figure 5-8):
FIGURE 5-8 WIRING SCHEMATIC FOR AN IPI SYSTEM TO THE CR310 USING RS232
DB9 CONNECTOR
In the event that the C1 and C2 ports are vacant, the C1 and C2 ports can be used
in place of the DB9 port. See the wiring diagram outlined in Figure 5-9.

5.3.1 Updating the Modbus Addresses With a CR310
Before updating the Modbus addresses on the IPI string, ensure that all settings
have been saved on the logger unit.
Modbus addresses for sensors connected to a Campbell CR310 logger can be
updated via a CRBasic code. Once the user has defined the number of sensors
and their respective serial numbers, the code will automatically assign a Modbus
address to each sensor in the string once the code is run.
1. Open LoggerNet.
2. Navigate to the “CRBasic Editor” option under the Program menu (Figure 5-2).
NOTE: AN RS485 TO RS232 INTERFACE MUST BE USED WHEN UPDATING THE
MODBUS ADDRESSES WITH A CR310 LOGGER.
