WD – Data Out
Purpose Selects the data types collected by the Channel Master.
Format WD abc def ghi
Range Firmware switches (see description)
Default WD 111 100 000
Recommended Setting. The default setting for this command is
recommended for most applications.
Description WD uses firmware switches to tell the Channel Master the
types of data to collect. The Channel Master always collects
header data, fixed and variable leader data, and checksum
data. Setting a bit to one tells the Channel Master to collect
that data type. The bits are described as follows:
a = Velocity d = Percent good g = Reserved
b = Correlation e = Reserved h = Reserved
c = Echo Intensity f = Reserved I = Reserved
Example WD 111 100 000 (default) tells the Channel Master to collect
velocity, correlation magnitude, echo intensity, and percent-
good.
Notes 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 Channel Master does not collect water-
track data.
3. Spaces in the command line are allowed.
WF – Blank after Transmit
Purpose Moves the location of first 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 (328 feet)
Default WF0050 (1200kHz), WF0100 (600kHz), WF0200 (300kHz)
Recommended Setting. The default setting for this command is
recommended for most applications.
