5 LISST-Holo Field Deployment
5.1 Introduction The LISST-HOLO has many features that make it easy to deploy in the field.
Start and Stop conditions can be programmed into the instrument in advance.
Once the instrument is turned on it will wait for the Start Condition to occur
before capturing holograms. It will continue to capture holograms at the
programmed rate until the stop condition is reached.
The holograms are stored either on an External Memory Module (EMM) if it is
installed on the 8-pin connector on the endcap. If the EMM is not installed,
holograms will be stored on the internal drive (32 GB) of the LISST-HOLO. The
EMM is pressure rated to the same depth as the LISST-HOLO (300m).
Up to four different set of Start, Stop, and Sampling conditions can be pre-
programmed into the LISST-HOLO.
The sections below describe in detail how to configure, start, and stop the data
collection as well as how to offload hologram from the EMM and the internal
drive.
5.2 Programming To configure the Start and Stop conditions you must connect to the instrument
using the Ethernet connection as described in Sections 3.2 and 3.3.
Clicking on the Home tab will show a summary of the four sets of sampling
conditions. Each of the four sets can be configured differently. To set up a
sampling program click on the Program # hyperlink.
The Start Condition, Sampling mode and rate, and the Stop Condition will need
to be set.
To set the Start condition choose between a Date/Time start, delayed start,
depth start, External Signal 1, External Signal 2, or the Magnetic Switch.
To set the sample mode, choose between Fixed rate and burst sampling.
Date/Time start will wait until the selected GMT time is reached before sampling
is started and the magnetic switch is in the 1 position. If it is past the specified
time the sampling will start immediately if the magnetic switch is in the 1
position. Be sure to check the homepage to make sure your LISST-HOLO has
the correct GMT time.
