All of the settings controlling HydroStar are found in menus under the main
Options menu. Click on the Options button on the main screen and then click
on the next Options button to find these menus.
HydroStar Appearance
Reverse Video - In the usual color scheme (No), the graphics appear in light
colors on a black background. Set this to Yes if you prefer dark colors on a
white background.
Full Keyboard - With this set to Yes, a full keyboard will appear on screen
each time you are asked to input something. Set it to No if you prefer a partial
keyboard.
Use Colors in Plan View - If your monitor is color, this should be set to Yes.
Vehicle File - The filename of your vehicle file (barge.veh) should appear here.
If it doesn’t, click on this button. You will see a button for each vehicle file that
exists in your Data directory. Click on the barge.veh button.
General Options
Rod Height - This value is the vertical distance from GPS Antenna 1 to the water surface. It’s very
important that this is set correctly if you are collecting points with the depth sounder. Like all measure-
ments, use the same units you are working in.
Coordinate File - All points are stored in the coordinate file. Click on this button to change the current
file or create a new one. The coordinate file is stored in the Data directory.
RMS Tolerance - RMS is a measurement of the accuracy of the position being reported by the GPS
receivers. HydroStar will warn you if you try to collect points when the RMS is higher than this limit.
That means the position isn’t accurate enough. Default value: 1.
GPS COM Port - GPS Receiver One is attached to the computer using a serial cable plugged into this
nine-pin COM port.
PCMCIA Drive - If files are to be transfered using a PCMCIA card, this is the location of the PCMCIA
slot. If you will not be using one, do not worry about this setting. (HydroStar was originally designed
for touch-screen computers without disk drives.)
Use Second GPS - This should be set to Yes since HydroStar needs position information from both
receivers to determine the orientation of the barge and the location of the pile driver or depth sounder.
Second GPS COM Port - GPS Receiver Two is attached to the computer at this COM port.
Use Depth Sounder - If this is set to Yes, HydroStar will read the depth sounder each time you collect
a point to find the elevation of the underwater terrain.
Depth Sounder COM Port - The COM port on the computer where the depth sounder is attached.
