NetSensor Cast Temperature Data Format
Parameter	Bytes	Notes
Note		All data on a line are comma separated; all lines are terminated with <CR><LF>
Line 1, cast header
Cast number, NetSensor ID	2, ASCII	Cast number automatically sequenced; NetSensor ID fixed.
Line 2, cast data
Cast segments	1	Usually three (net down, fishing, net up)
Cast segment 1 temperature, pressure count	2
Cast segment 1 sample rate, seconds	1	Net down, usually 2s.
Cast segment 2 temperature, pressure count	2
Cast segment 2 sample rate, seconds	1	Fishing, usually 60s.
Cast segment 3 temperature, pressure count	2
Cast segment 3 sample rate, seconds	1	Net up, usually 2s.

Cast segment n, count	2
Cast segment n, sample rate, seconds	1
Age of first value, seconds	3	Time of first sample is data capture time less age.
Lines 3 to total count, temperature/pressure data
Temperature, pressure	ASCII	Temperature plus 5C,  0 - 50.00 (subtract 5 for in situ temperature).;                        Absolute pressure in decibars, 0 - 340 db (subtract 10 for atmospheric pressure; divide by 10 for meters).
Cast data terminator line	0,0
Checksum Line	2	Sum of temperature times 100 and pressures, modulo 65536.
