14.3 Head Commands, Binary Format
Cmd Format Units Values Description
ABS0 f32 dB/km 0 to 200 Absorption
AIB0 f32 dB 0 to 60 Acoustic image brightness
AIH0 u32 lines 0 = off
wedge radius in pixels Acoustic imagery height. Set to
display wedge radius in pixels.
Head will return requested lines
or less, usually less. Larger
values will increase Ethernet
data rate.
AUT0 u32 Flag bits
0x00000001 = auto power on
0x00000100 = auto gain on
0x00010000 = auto range on [7:0] auto power (not functional)
[15:8] auto gain (not functional)
[23:16] auto range
[31:24] spare
Auto power/gain work in tandem,
thus both are enabled/disabled at
same time.
BIE0 u32 0 = off
1 = on Bathy intensity enable
BMAX f32 metres 0 to 999 Max range filter
Head default = 999
Deprecated 12 Dec 2011, see RGB0
BMIN f32 metres 0 to 500 Min range filter
Head default = 0
Deprecated 12 Dec 2011, see RGA0
BOS0 u32 0 = Equiangle
1 = Equidistant Bottom sampling
DGA0 f32 metres 0 to 1200 depth gate min
DGB0 f32 metres 0 to 1200 depth gate max
DGO0 u32 0x00000000 = gates off
0x00000001 = manual gates
0x0000ww02 = auto gates
0x0000ww03 = auto gate/slope
where ww = gate width in ±
percent of depth (5% to 90%) Depth gates control. Manual gates
mode require DGA0, DGB0, DGS0 to
be set. In auto gates mode, a
peak percentage value for gate
width must be supplied in bits
[15:8] in this command.
DGS0 f32 radians
-
π
/2 to +
π
/2
depth gate slope
DHM0 u32 0 = single head
1 = master simultaneous, dual
2 = master alternating, dual
3 = slave simultaneous, dual
4 = slave alternating, dual Head sync mode
(single and dual head modes)
DYNA u32 0xaabbbccc
aa = spare
bbb = slope control
ccc = depth control
ex: 0x003d0523 shows a bottom
at 5m depth which wobbles. Generates a moving simulated
bottom for testing auto gate
features.
Three control bits:
[0:0] = magnitude (0-f)
[1:1] =
∆
magnitude (0-f)
[2:2] = rate of change (0-f)
*DYNA is also supported as an
ASCII command (enter hex digits
without the ‘0x’)
FILT u32 0 = off
1 = range
2 = depth
3 = range & depth FILT is deprecated. Do not use
(10 Mar 2011). Use DGO0, RGA0,
RGB0.
FIL0 u32 0 = single
1 = double
2 = quad Bottom fill enhancement (High
Density mode.)
FRQ0 f32 Hz 200000 to 400000, and 700000 Frequency in Hz
