1. INTRODUCTION
The GK-405 Vibrating Wire Readout is made up of two components:
•The Readout Unit, consisting of a Windows Mobile handheld PC running the GK-405
Vibrating Wire Readout Application
•The GK-405 Remote Module is housed in a weatherproof enclosure and connects to the
vibrating wire gage to be measured.
Figure 1 - GK-405 with Handheld PC in Cradle (Shown with the FPC-2)
The two components communicate wirelessly using Bluetooth®, a reliable digital
communications protocol. The Readout Unit can operate from the cradle of the Remote Module
(as shown in Figure 1) or, if more convenient, can be removed and operated up to 20 meters from
the Remote Module. (Note: In most cases 20 meters will be the maximum but differences in
battery, atmospheric and geographic conditions may reduce the actual effective range.)

2
1.1 Features

2. INSTALLATION AND OPERATION
NOTE: For those users that have purchased a complete GK-405 system the Field PC has been
pre-programmed to operate with the GK-405. This includes the Bluetooth pairing between the
Field PC and the GK-405.
The steps described in Sections 2.1 and 2.2 are an attempt to guide the user through the process
of launching the GK-405 VWRA, connecting to the sensor, and taking a reading. If all parts of
the GK-405 are purchased as a system, Geokon makes every effort to ensure that the system is
completely set up and working before it leaves the factory. Other times, the user may already
own the handheld PC and are setting up their hardware and software for the very first time. The
steps below attempt to cover all cases and refer the user to the appropriate section when more
information is needed.
For those users that have purchased a complete GK-405 system, a workspace with the name of
“GK405” will have been predefined and the handheld unit will already be paired with the
Remote Module. Note that the workspace name can be changed at any time (see Section 4) or
new ones can be created (see Section 3.4). When purchasing a GK-405 system, Sections 2.2
through 2.4 can possibly be skipped but a quick review is recommended.
2.1 Connecting Sensors
2.1.1 Sensors with 10-pin Connectors Attached
Align the grooves on the sensor connector (male), with the appropriate connector on the
readout (female connector labeled senor or load cell). Push the connector into place, and
then twist the outer ring of the male connector until it locks into place. For more
information on the sensor connectors of the remote module, refer to Appendix A.
2.1.2 Sensors with Bare Leads
Attach the GK-403-2 flying leads to the GK-405 by aligning the grooves on connector of
the flying leads (male), with the connector on the unit (female). Push the connector into
place and then twist the outer ring of the male connector until it locks into place. Attach
the bare leads of a Geokon vibrating wire sensor by connecting each of the clips on the
leads to the matching colors of the sensor conductors, with blue representing the shield
(bare).
2.2 Initial Quick Start Sequence
The following steps are a guide to the typical operation of the GK-405 and, if followed, should
result in a successful sensor measurement:
1) If the Remote Module has been previously paired with the handheld unit, then press the
button labeled “POWER ON (BLUETOOTH)”. A blue light should turn on and begin
blinking, signifying that the Remote Module is waiting to connect to the handheld unit.

5
If the Remote Module was purchased separately from the handheld unit, see Section 2.3,
“Establishing Contact with the Remote Module”.
Launch the GK-405 VWRA by tapping on “Start” from the handheld PC’s
main window, then tap “Programs”, and then tap the GK-405 VWRA icon
(shown to the right).
If the GK-405 Vibrating Wire Readout Application has not been installed, please see Section
2.4, “Installing the GK-405 VWRA”.
2) After a few seconds, the blue light on the Remote Module should change to a steady state
blue (lit but not flashing) and the Live Readings Window will be displayed (Figure 4). If the
window shown in Figure 5 is displayed instead of the Live Readings Window, please refer to
Section 2.5, “Starting the Vibrating Wire Readout the first time”. If the Live Readings
Window is displayed but no Thermistor or Vibrating Wire output is shown, please refer to
Appendix A, “GK-405 Connections”.
Figure 5 - Select Workspace Name
3) From the Live Readings Window, different display modes may be selected as appropriate for
the sensor (see Section 3.2.1, “Display Mode”). If a sensor is connected that contains more
than one vibrating wire “cell”, the “Sensor Index” may be changed to view the vibrating wire
output for each “cell”, or the average may be displayed.
4) If displaying sensor output in engineering units is desired, tap on “View” then “Sensor
Selection Screen” to select a predefined sensor or to create a new sensor configuration.
Please refer to Section 3.3, “Sensor Selection Screen” as well as, Section 4.2, “Sensor
Configuration”.
5) To close the GK-405 VWRA from the Live Readings Screen, tap “Menu” then “Close GK-
405”.

2.3 Establishing Contact with the Remote Module
In general, this should only need to be done once and is typically done before it leaves the
factory. Follow the steps below to ensure the ‘partnership’ with the remote is established before
using the readout software:
1) Use the Bluetooth Settings Manager on the handheld PC to set up the link to the remote.
Read about setting up a Bluetooth “partnership” in Chapter 9 of the handheld PC’s Reference
Guide. See Figure 6 below for two examples of how to start Bluetooth Manager.
Figure 6 - Starting Bluetooth Manager
2) Once in the Bluetooth Settings Manager, click on the “Mode” tab and then make sure that the
box next to “Turn on Bluetooth” is checked (Figure 7).
Figure 7 - Turn on Bluetooth
Two ways to start the
Bluetooth Manager

3) Click on the “Devices” tab, if it shows a “Geokon” device (name will start with “GK405”
and contain the remote’s serial number), go to step six. Otherwise, turn on the remote module
(should see a flashing blue indicator on the remote) and select “Add new device…”.
Figure 8 - Add New Device
4) When a suitable remote is discovered, highlight the device and tap “Next”.
Figure 9 - Select a Bluetooth Device

5) A prompt will be displayed for a password; enter “default” and tap “Next” again. If a
partnership with the device is successfully established, the screen will momentarily display
the prompt shown at the bottom of Figure 10 and then return to the Bluetooth Devices screen.
Figure 10 - Enter Passcode
6) Click on the COM Ports tab, if the “Geokon” device is already assigned to a COM Port skip
to step nine. If no COM Port is assigned, tap on “New Outgoing Port”. In the example shown
in Figure 11, there is no COM Port assigned to a “GK405” device.
Figure 11 - New Outgoing Port

7) The screen shown in Figure 12 will be displayed. Select the appropriate device from the list
and tap “Next”.
Figure 12 - Add a Device
8) From the “Port:” dropdown list, select a COM port (COM5 is the default). Be sure to
remember the number of the COM port as you may have to select it later in the readout
software (see Section 3.5.3). Make sure to “uncheck” the “Secure Connection” checkbox
(Figure 13). Tap “Finish” when done to return to the Bluetooth Settings “COM Ports” screen.
Note: If using a Nautiz X7, COM5 may be available, depending on the model.

9) Lastly verify that the Bluetooth device is set for Serial Port operation. From the “Devices”
tab of the Bluetooth Settings manager, tap the device to be used to communicate with the
remote. Figure 14 will be displayed. Ensure that the “Serial Port” checkbox is checked. Tap
“Save” to complete the Bluetooth Settings.
Figure 14 - Serial Port Check Box
NOTE: After “Save” is selected, you will be brought back to the “Devices” window. There will
be a “Connect” button available at the bottom of the screen. See Figure 15 below.
DO NOT USE THE “CONNECT” BUTTON TO TEST THE CONNECTION!
It will always fail after the pairing has been made successfully. Test the pairing by entering the
GK-405 VWRA application.
Figure 15 - Connect Button

2.4 Installing the GK-405 VWRA
The installation of the GK-405 VWRA requires the following:
•A Handheld device (HHD) running Windows Mobile Classic 5.X (6.X recommended) or
higher with at least 50 Mbytes of free memory.
•HHD must be Bluetooth enabled and able to assign a Bluetooth connection to a COM
port.
•Windows .NET 3.5 Compact Framework (CF) and .NET framework English Language
Messages Package installed on HHD.
•Both “CAB” file installers are included in the GK-405 VWRA installer “Zip” file,
available on Geokon’s website (http://www.geokon.com/GK-405).
•Microsoft ActiveSync version 4.5.0 or higher installed on the host PC if host PC
operating on Windows XP (see Figure 16). If host PC’s operating system is Vista,
Windows 7 or Windows 8 then Windows Mobile Device Center should be installed on
the host PC (Figure 17 on the following page). An active connection between the host PC
and the HHD must be established either via a physical link or Bluetooth.
Note: For customers using a PC running Window 10 operating system; Windows Mobile Device
Center (WMDC) may no longer operate as it should because of an operating system update
(released October of 2017) called “Fall Creator Update”. If WMDC no longer launches when a
mobile device is connected via USB cable or will not manually launch, the link below should
help fix the issue. Please note that administrative privileges are need to launch some of the files
involved in the fix so your local IT person may need to be involved. The fix can be accessed via
the following link:
https://www.handheldgroup.com/support-rugged-computers/knowledgebase-KB/22996/
Should the link above fail to fix the WMDC launch problem, the link below offers another
