WC – Correlation Threshold
Purpose Sets the minimum threshold for correlation magnitude that velocity data must meet to be
considered valid.
Format WCnnn, nnn, nnn
Range nnn = 0 to 255 counts
Default WC 064,080,096
Recommended Setting. The default setting for this command is recommended for most applications.
Description The RiverPro/RioPro uses WC to screen water-track data for the minimum acceptable
correlation requirements. The nominal (maximum) correlation depends on system fre-
quency and depth cell size (WS). WC sets the threshold of the correlation below, which
the ADCP flags the data as bad and does not average the data into the ensemble. The sec-
ond and third thresholds are used for Water Mode 3 (WM3) so different thresholds can
be set for mode 2 type ping, coherent pings, or pulse-to-pulse pings.
The default threshold is 64 counts. A solid target would have a correlation of 128 counts.
WD – Data Out
Purpose Selects the data types collected by the RiverPro/RioPro.
Format WD v;c;a;p;s;*;*;*;*;m
Range Firmware switches (see description)
Default WD 1110000001
Recommended Setting. The default setting for this command is recommended for most applications.
Description WD uses firmware switches to tell the RiverPro/RioPro the types of data to collect. The
RiverPro/RioPro always collects header data, fixed and variable leader data, and check-
sum data. Setting a bit to one tells the RiverPro/RioPro 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 *= Reserved m = Beam Correction Ma-
trix
Example WD 1110000001 (default) tells the RiverPro/RioPro to collect velocity, correlation magni-
tude, echo intensity, percent-good, 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 RiverPro/RioPro 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.
