CTD
---------------
Sample Rate (Hz): 1.830000
data saving starts at 09:55:12.34; data saving ends at 14-12-18-17_13_54_.35
File Header String: FSI
The CTD records Conductivity, Temperature, and Pressure (in that order) to the raw data text file.
Units are:
Conductivity (mmho/cm)
Temperature (C)
Pressure (dBars)
Pressure is converted internally into psi for display purpose. It is stored as dBars in the raw data file.

Orientation
---------------
File Header String: o
Orientation records Compass, Pitch, Roll, and Compass temperature (in that order) to raw data text file
Sample Rate (Hz): 0.000000

Notes:
The data file is laid out in an alternating sequence of data
segments of size specified by "Samples to read". The 
segments come from alternating channels. 
(ex: ch0,ch1,ch2,ch3,ch0,ch1,ch2,ch3...)
The DAQmx reads 24-bit samples. They are recorded by
Labview in a 32-bit signed integer value. 

In order to determine the span of time that the data within
a file covers you need to take a product of "Samples To Read"
and the "Segment/file". Divide that by the "Sample Rate".

"Segment/file" value specifies how many "Samples to Read" 
segments are recorded in each file.

"Byte Ordering" field describes the Endian order with which 
the given data was recorded.

"Start DAQ" is the minimum depth at which the VI will begin 
data aquisition. 

"Drop Weight" the target depth of the deployment. The
fuse wire will burn when the device reaches this depth.

"Stop DAQ" the depth that will stop the data acquisition
during the ascent phase.

"Descent Check Depth Delta" the minimum amount of depth required
to satisfy the descent rate.

"Descent Check Time Period" the time span at which the depth
readings are taken for the descent rate calculation. 

"Burn Time" the amount of time in minutes that the burn wire 
signal will be high.

"Failsafe Time" hour and minute value is the amount of time before
the device issues a wire burn. This is used as a failsafe measure
in case anything happens.

"Burn Check Depth Delta" the minimum amount of depth needed to stop
the burn.

"Burn Check Time Period" the time pariods used to check if there is a 
difference in depth.
