4. Operation
Once a system has been installed in conjunction with the relevant sections of this manual and
any relevant sensor manuals, it can be tested in air by powering up the system and observing
that communications with the subsea device(s) is established.
Caution
The power should be turned off before making a connection between the sonar
head and surface controller (SCU or SeaHub).
When the SCU and subsea heads are switched on, the system display will appear on
the monitor after a few seconds delay. Until the SCU, Remote Access Terminal (RAT),
and Subsea elements are communicating correctly, the Status Bar will display a Timeout
(‘Timeout Node xx’) message for each Node that it is trying to communicate with. These
messages will be removed from the display as each subsea device is detected as operating
correctly.
If the RAT or subsea elements are not powered up, not present, or have a fault somewhere,
then error messages will be shown in the status bar boxes on the bottom of the display. If
error messages appear, check that all the system parts are connected and that all leads/
cables are correctly installed.
The following sections of this manual will describe the general software controls in addition
to installation and connection instructions. Further, separate manual sections will describe
operation of each of the subsea Sensors and their connection details.
Full details of the Seanet Pro and Seanet Setup operation can be found in the Seanet Pro
Software Manual. There are also a number of devices that can be connected to the Seanet
SCU including Imaging Sonar, Profiler, Bathymetric and Sidescan. Refer to the individual
device manual for specific details of their screen controls and functions.
Note
The four DE-9 ports are labelled as
ScuA
to
ScuD
in
Seanet Setup
. These are
assigned virtual port numbering in Windows®. Two other ports will be shown,
ScuMain
and
ScuAux
- these are used for communication inside the SCU and
not for external devices.
The port numbering will be re-set if a system restore is performed and due to the manner in
which Windows® manages resources the ports may be numbered differently each time the
system is restored. If desired they can be manually re-assigned from the Windows® Control
Panel.
