All names and descriptions must be in upper case. The utility will convert them if they are not. Characters not available

from the NorthStar's keyboard are removed before uploading to the NorthStar to avoid problems.

The uploader will use the first 16 characters of the description as the waypoint description.

The downloader will store the avoidance radius as the next 6 characters of the Comments field. On uploading, if the data

in the Comments field is a number from 0.01 to 1.00, it will use that as the avoidance radius.

The NorthStar does not report icons associated with the waypoint to the utility, so they are lost in the translation.

Instructions:

The NorthStar must be set up to see the proper communications port. Remember to record any changes you make to the

configuration so that you can undo them later to restore the GPS to its original configuration.

Push the star (*) key enough times to see the User Customization tab

Push the Port Setup Options tab and go to the RS232 Setup; edit

Set the RS232 port to Copy Port 1 and use 4800 or 9600 baud.

Connect the interface cable to the computer’s serial port or to the serial to USB converter.

Run the NorthStar Loader Utility

The NorthStar utility starts when called from the SeaMarks program's Tools>Upload/Download>NorthStar

selection. You normally enter as either uploading or downloading. Keep in mind, which one you used as the NorthStar

loader does not know or care, but the subsequent actions by the SeaMarks program depend on it.

Select the COM port. On old desktop computers, the mouse is on COM1 unless it uses a PS-2 mouse so try COM2 too.

If you are suing a USB to serial converter, it will often be found on COM4. If you cannot figure out what COM port the

device is on, then you need to run the Windows' Device Manager and check the Port settings.

The very first step should be to verify that communications is established by pushing the test communications button.

If all is well, the utility will read the software version from the Northstar and report it in the activity window. If the

communications is not established, then try other communications settings until it is.

Then download what is in the NorthStar to save it. You will see the download activity and a done indication. This

utility then creates a file called "north2logps.dbf" and then waits for further instructions. Quit the NorthStar loader to

return to the SeaMarks program. You will get a dialog that asks if the NorthStar loader is finished. Assuming it is done,

push OK and the program will open that new file and display it.

For Downloading from the Northstar to the PC:

The steps of operation are as follows: First the program halts and calls the NorthStar loader utility. The NorthStar loader

utility reads the waypoints from the GPS and creates a file called: north2logps.dbf. Then the user quits the NorthStar

loader and control returns to the program, which then reads the file and makes it the current file. The program instructs

you to wait until the NorthStar loader is finished so that the file will be fully prepared for loading. You should "Save

As" the file to a different name after you are done.

If any of the waypoints were stored as a Loran number set the Loran Chain for the program. The Loran Chain is an

artificially selected number from 1 to 8 that only has meaning to the SeaMarks program.

For Uploading from the PC to the Northstar:

The steps of operation are as follows: First the program saves the current file to the disk as: logps2north.dbf. It then

pauses and calls the NorthStar loader utility. The NorthStar loader utility reads the file and writes the waypoints to the

GPS. Then the user quits the NorthStar loader and control returns to the program.

You may either clear the waypoint storage and add all new waypoints or just add more waypoints (ADD/REPLACE) to

what is already there. Remember that if any of the new waypoints have identical NAMES to the existing ones, the old

one will be replaced.

You can upload the waypoints as Loran or Lat/Lon by checking the box. If you upload as Loran, the Northstar will

calculate the Lat/Lon itself and that may differ slightly from the program's conversion. If you upload as Lat/Lon, the

process will use the program’s value for the Lat/Lon.

When uploading as Loran, the Northstar needs to be informed of the GRI of the Loran numbers. Set the GRI to the

appropriate number. For example, the Southeast US uses GRI number 7980.
