Why can't I see my data in MapView
Why is my 3D terrian all white or all blue
Why can't I see my 3D terrain
Why isn't my boat tracking across the screen?
Why can't I see my net?
Why can't I see my Simrad ITI net?
Why can't I record my net trackline?
Why does my net look so small in relation to the terrain and
boat?
Why is performance so slow after rendering?
Check what resolution you
are in. In PISCATUS3D
DeepSea Pro and PISCATUS3D
Inshore Pro, the 100nm
resolutions draw the 3D terrain from the satellite data only, not
any of your boat data. Try
selecting a smaller area to view - 60nm for PISCATUS3D
DeepSea Pro and 20nm for PISCATUS3D
Inshore Pro - these
draw the 3D terrain from the actual boat data.
On the PISCATUS3D
tool bar, check the colour
scale and its associated values.
If your 3D terrain appears all white it means your terrain is
much shallower than the minimum depth specified on the colour bar
and you need to reduce it. Likewise,
if your terrain appears all blue it means your terrain is much
deeper than the maximum depth specified on the colour bar and you
need to increase it.
Of course, if you are using
a different colour palette to the default one, you won’t
necessarily see an all-white or all-blue terrain, it may be some
other colour.
Check that PISCATUS3D
is running off the correct
monitor and graphics card. To check this you need to open the PISCATUS3D
‘System Information’ window by selecting
Help | Support | System Information from the PISCATUS3D
menus.
This window is shown below. At the bottom of the window the
graphics card used is listed. This needs to be an nVidia card no
older than an GeForce 4 FX5200. If it is not your GeForce card, try
swapping the monitor cables around so PISCATUS3D
runs off your other monitor.
Check that you have the ‘Follow Boat’ option
ticked in the upper left hand corner of your PISCATUS3D
screen. If this does not
solve your problem, check you have incoming data from your GPS. To
do this, right click the SeaLog icon in the System Tray in the
bottom right hand corner of your screen, and select ‘View Info’.
This will bring up a ‘SeaLog Info’ window like the one shown
below. In here you will
see the time, date, position and depth change as your boat moves
along.
If you have no SeaLog icon
in the System Tray it means SeaLog has not been started and is
therefore not running. You
should also notice that the first light in the PISCATUS3D
status bar is red, indicating SeaLog is not
running. Start SeaLog by clicking on the Start menu and selecting
Programs | Piscatus | SeaLog.
If there is no position
displayed in the ‘SeaLog Info’ window it means your GPS feed is
not getting through to your PISCATUS3D
computer. If this is
the case, check that your GPS is actually giving out a position and
that the multiplexer is both receiving and transmitting data. When the multiplexer is working correctly it will have a
power light on and one port will have a flashing light to indicate
it is receiving and another will have a flashing light to indicate
it is transmitting. If your multiplexer is having problems, try
turning it off and on again to reset it.
Check what resolution you
are in - in PISCATUS3D
DeepSea Pro the 100nm resolution does not allow
you to view your net. All the other resolutions do. Note that nets are not
available in PISCATUS3D
Inshore Pro.
Check what resolution you
are in - in PISCATUS3D
DeepSea Pro, the 100nm resolution does not allow
you to view your net. All the other resolutions do.
If this does not solve your
problem, check that you selected the ‘ITI’ option in your ‘Net
Details’ window when you initially put your net out.
To do this, click the Net button to open the ‘Net
Details’ window, and from the bottom drop down menu select
‘ITI’ as shown below. Click
the ‘Apply Net’ button to close the form.
If this does not solve your problem the next step
is to check that you are getting a Simrad ITI data feed into PISCATUS3D
. PISCATUS3D
has
a ‘Trawl Information’ window that displays information about the
net position, as shown below. To open this
‘Trawl Information’ window select Options | Trawl Info from the PISCATUS3D
menus. In here you will see net position and
depth readings.
If there are no net position
and depth readings then right click the SeaLog icon in the System
Tray in the bottom right hand corner of your screen, and select the
‘View Info’ option. This
will bring up a ‘SeaLog Info’ window like the one shown below.
In here you will see the net depth and position changing as
the boat moves along.
If you have no SeaLog icon
in the System Tray it means SeaLog has not been started and is
therefore not running. You
should also notice that the first light in the PISCATUS3D
status bar is red,
which indicates SeaLog is not running. Start SeaLog by clicking on
the Start menu and selecting Programs | Piscatus | SeaLog.
If there is no net
information displayed in the ‘SeaLog Info’ window it means your PISCATUS3D
computer is not receiving any Simrad ITI data.
If this is the case check that your PISCATUS3D
system has been set up to use Simrad ITI. To do this, right click the SeaLog icon in the System tray
and select ‘Piscatus Setup’.
This will open the ‘Piscatus Setup’ window like the one
shown over the page. In
the ‘Piscatus Setup’ window, make sure that ‘Simrad ITI’ and
‘CN22/4 Depth/Temp’ are selected in the ‘Net Monitor/s’
section, then click the ‘OK’ button.
If you still haven’t
solved your problem, it may be a hardware issue.
Check that the Simrad ITI is actually giving out a position
and that the multiplexer is both receiving and transmitting data.
When the multiplexer is working correctly it will have a
power light on and one port will have a flashing light to indicate
it is receiving and another will have a flashing light to indicate
it is transmitting. If your multiplexer is having problems try
turning it off and on again to reset it.
Net tracklines can only be
recorded when you have your net out and net data is coming into PISCATUS3D
. Net tracklines are not available in PISCATUS3D
Inshore Pro.
Net models are scaled to
true dimensions, the boat models are not. If you are at a large map
size (say 60nm resolution) it may be hard to see your net as it will
be quite small. Try decreasing your map size to a 20nm or 30nm
resolution.
If your computer is running
slowly after rendering has completed it may be due to heavy
contouring running in the background. After rendering has completed
and your 3D terrain has redrawn, the contours will be drawn.
Contouring is CPU intensive so if you are viewing a large area
and/or have a small contour interval, your system may run very
slowly until contouring has completed. Try decreasing the area
viewed or increasing the contour interval.
