Series 3000 Sonar System Operations and Maintenance Manual
Synchronize the internal clock. The <data> field is defined
as follows: mm,dd,yyyy,hh,mm,ss,mmm which is month,
day, year (4 digit), hours, minutes, seconds, and
milliseconds.
Prepare the system for shutdown. This puts the system in
standby, stops any recording, and closes all files. When
shutdown preparations are complete a status message is
issued and the SD value is set to one.
Take a snapshot image and save for subsequent transfer.
Setting d = 0 sets the image size to 16x1, d = 1 sets the
snapshot size to 32x32, d = 2 is 64x64, d = 3 is 128x128 and
d = 4 is 256x256.
Set standby mode, where d = 0 is normal and d = 1 puts the
system into standby (no trigger). Setting d = 2 puts the
system into low-power mode by shutting off the power to
the towfish (only supported in AUV configuration option,
see above). Default is normal (0).
Sets the speed of sound in cm/s. The data field is expected
to be of length six. Default is 150000 cm/s. Accepted range
is from 140000 to 160000.
Dump a status message. See below.
Set test mode where d = 0 is normal. Reserved for factory
test, do not access.
Set TVG page, where d = 0 – 15. Default is 7. Decreasing d
decreases the gain by 3dB whereas increasing d increases
gain by 3dB.
Triggers the system. This can be used as an alternate
triggering method. If the internal triggering is not desired
then the user can issue this command to trigger the system.
To use this command, place the system in standby (SM1)
first and then issue the command at the desired rate.
Sets the Trig 1 Out trigger type. For normal installations the
type is '0' and a pulse is generated simultaneous with the
towfish trigger. For the BlueFin AUV project the type
should be set to '1' which programs the port to output a
pulse 31 milliseconds prior to the end of the range and at a
rate such that the rate is maximum without exceeding 4 Hz.
Default is '0'.
