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.
