WD – Data Out
Purpose Selects the data types collected by the Sentinel V Real-Time.
Format WD (v;c;a;p;s;*;*;*;i;m)
Range Firmware switches (see description)
Default WD 111 100 001 1
Recommended Setting. The default setting for this command is recommended for most applications.
Description WD uses firmware switches to tell the Sentinel V Real-Time the types of data to collect. The
Sentinel V Real-Time always collects header data, fixed and variable leader data, and
checksum data. Setting a bit to one tells the Sentinel V Real-Time to collect that data type.
The bits are described as follows:
v
= Velocity
c
= Correlation
a
= Echo Intensity
p
= Percent good s = Status
*
= Reserved
*
= Reserved
*
= Reserved
i
= ADC&Config
m
= Beam Correction Matrix
Example WD 1111000011 (default) tells the Sentinel V Real-Time to collect velocity, correlation mag-
nitude, echo intensity, percent-good, ADC and Configuration, and beam correction matrix.
1. Each bit can have a value of one or zero. Setting a bit to one means output data, zero
means suppress data.
2. If WP = zero, the Sentinel V Real-Time does not collect water-profile data.
3. Spaces in the command line are allowed.
4. Status data is not used, as it does not mean anything.
WF – Blank after Transmit
Purpose Moves the location of first depth cell away from the transducer head to allow the transmit
circuits time to recover before the receive cycle begins.
Format WFnnnn
Range nnnn = 0 to 9999 cm
Default See Table 32
Recommended Setting. It is not recommended to set the blank below the default value shown in Table
32. If you are using
Plan
, let the software set the WF command setting.
Description WF positions the start of the first depth cell at some vertical distance from the transducer
head. This allows the Sentinel V Real-Time transmit circuits time to recover before begin-
ning the receive cycle. In effect, WF blanks out bad data close to the transducer head, thus
creating a depth window that reduces unwanted data in the ensemble. The default value is
based on system frequency and it is highly recommended to use this value. Setting a value
below the default blank distance may show ringing/recovery problems in the first depth
cells.
