Field Description
EZ / Sensor Source Contains the selected source of environmental sensor data (EZ-command). These
firmware switches indicate the following.
FIELD
x1xxxxxx = CALCULATES EC (SPEED OF SOUND) FROM
xx1xxxxx = USES ED FROM DEPTH SENSOR
xxx1xxxx = USES EH FROM TRANSDUCER HEADING
xxxx1xxx = USES EP FROM TRANSDUCER PITCH SENSOR
xxxxx1xx = USES ER FROM TRANSDUCER ROLL SENSOR
xxxxxx1x = USES ES (SALINITY) FROM CONDUCTIVITY
xxxxxxx1 = USES ET FROM TRANSDUCER TEMPERATURE
NOTE: If the field = 0, or if the sensor is not available, the H-ADCP uses the manual
command setting. If the field = 1, the H-ADCP uses the reading from the internal sen-
sor or an external synchro sensor (only applicable to heading, roll, and pitch). Although
you can enter a "2" in the EZ-command string, the H-ADCP only displays a 0 (manual)
or 1 (int/ext sensor).
Sensor Avail This field reflects which sensors are available. The bit pattern is the same as listed for
the EZ-command (above).
dis1 / Bin 1 distance This field contains the distance to the middle of the first depth cell (bin). This distance
is a function of depth cell length (WS), the profiling mode (WM), the blank after
transmit distance (WF), and speed of sound.
Scaling: LSD = 1 centimeter; Range = 0 to 65535 cm (2150 feet)
WT Xmit pulse This field, set by the WT-command, contains the length of the transmit pulse. When
length the H-ADCP receives a <BREAK> signal, it sets the transmit pulse length as close as
possible to the depth cell length (WS-command). This means the H-ADCP uses a WT
command of zero. However, the WT field contains the actual length of the transmit
pulse used.
Scaling: LSD = 1 centimeter; Range = 0 to 65535 cm (2150 feet)
WL / WP Ref Lyr Avg Contains the starting depth cell (LSB, byte 37) and the ending depth cell (MSB, byte 38)
(Starting cell, Ending used for water reference layer averaging (WL-command).
cell)
Scaling: LSD = 1 depth cell; Range = 1 to 128 depth cells
WA / False Target Contains the threshold value used to reject data received from a false target, usually
Threshold fish (WA-command).
Scaling: LSD = 1 count; Range = 0 to 255 counts (255 disables)
Spare Contains the CX-command setting. Range = 0 to 5
LagD / Transmit lag This field, determined mainly by the setting of the WM-command, contains the dis-
distance tance between pulse repetitions.
Scaling: LSD = 1 centimeter; Range = 0 to 65535 centimeters
CPU Board Serial Contains the serial number of the CPU board. The CPU Board Serial number is stored in
Number Big Endian (MSB sent first).
WB / System Band- Contains the WB-command setting. Range = 0 to 1
width
System Power Contains the CQ-command setting. Range 0 to 255.

sent first).
