36 ADVField Operation Manual (September 1, 2001)
StartTime or ST [hh:mm:ss]
•
Default parameter:
00:00:00
(midnight)
•
Without parameter: returns the current deployment’s starting time.
•
When given with a time in a valid format, where hh=hour (2 digits; 24-hour clock),
mm=minute (2 digits), and ss=seconds (2 digits): sets the time data collection will begin.
•
If
StartDate
and
StartTime
are before the current date and time, data collection will begin
immediately following a 2-3 second delay for ADV initialization.
•
Example:
ST 13:05:00
tells the ADV to start data collection at 1:05 p.m.
•
See Note for the
StartDate
command (above).
SampRate or SR [d.d] [d.d] [d.d]
•
Default parameters:
10.0 0.0 0.0
(Hz)
•
Parameter range:
0.1
to
50.0
(Hz)
•
Without parameter: returns its current settings for each burst type.
•
When used with from one to three valid parameters, sets the sampling rate in Hz for each
burst type. This setting determines the rate at which ADV velocity data is recorded.
•
The ADV will ping as rapidly as possible and average pings to meet the specified sampling
rate (see §1.3)
•
SampRate
is also listed under setup commands (§3.6). For autonomous deployments, the
ADVField supports up to three sampling rates for three burst types (see §1.3 for a descrip-
tion of multiple-burst sampling). For real-time data collection, only the first of these three
sampling rates is used (this is the rate listed by the
Show Setup
command).
•
To select multiple-burst sampling, enter a separate sampling rate for each burst type desired.
For example,
SR 0.2 2.0 25.0
sets the sampling rate for burst type #1 to 0.2 Hz, for burst
type #2 to 2.0 Hz, and for burst type #3 to 25.0 Hz. If only one or two input arguments are
specified, the values for the other burst types are set to 0, disabling that burst type.
•
Note:
When the following optional sensors are used, the maximum sampling rate is limited
to the listed value. To collect data at higher rates, you can disable the pressure sensor using
the
ExtPressureSensorInstalled
command (see §3.9).
○ Serial Paros external pressure sensor: 4 Hz
○ Frequency pressure sensor: 10 Hz
BurstInterval or BI [d] [d] [d]
•
Default parameters:
1200 0 0
(seconds; 20 minutes)
•
Parameter range:
5
to
43200
(seconds; maximum is equivalent to 12 hours)
•
Without parameter: returns its current settings for each burst type.
•
When used with from one to three valid parameters, the burst interval for each burst type is
set to its corresponding value (in seconds). See §1.3 for a description of burst sampling.
•
For autonomous deployments, the ADVField supports up to three burst interval values for
three burst types. Burst interval is not used during real-time data collection.
•
To select multiple-burst sampling, enter a separate burst interval for each burst type desired.
For example:
BI 1200 3600 7200
sets the burst interval for burst type #1 to 1200 seconds
(20 minutes), for burst type #2 to 3600 seconds (1 hour), and for burst type #3 to 7200 sec-
onds (2 hours). If only one or two input arguments are specified, the values for the other
burst types are set to 0, disabling that burst type.
