Overview:
	IBIS is a navigation system for Windows PCs providing...

	In the shareware version:
	A supplemental charting and navigational system that uses input
	from a GPS along with charts, GPS type road display and other 
	various displays providing a comprehensive navigation tool set.

	Custom installations:
	An interface black box to allow multiple devices as input
	such as wind instruments, depth, or other NMEA devices as
	well as analog sensor inputs. Engine, electrical and 
	environmental variables monitor	using the various sensors. 
	
System Requirements:
	Version 2.1 Windows 3.1 or greater
	Version 3.0 Windows 95 or greater
	Mouse and available serial port for GPS, Black Box, etc.
	Super VGA with 800 x 600 x 256 colors. 
	Min. 486 with 8 Megs memory. 
	
Installation: (Simtel version)
	Download IBIS.ZIP
	
	This program requires VBRUN300.DLL which is not included because of
	its size.  It is available from the Simtel.Net as vbrun300.zip.  It
	is also available from many on-line services and BBSs. Download it 
	first and copy to windows\system directory.

	Unzip the ibis.zip file into a temp folder, then ...

	End other programs that are running (especially VB programs).
	Run SETUP.EXE to install. Then start program from the icon.
	Set comm port in the config screen at first time program start.
	(Ignore any error concerning comm port on first time start).

Version Fix/Enhancement releases:
	Periodically, there will be fixes and enhancements added.
	Minor revisions and bug fixes can be told by the
	file dates. Major changes will have new version numbers. 
	When you see these, download and install per
	instructions in this .TXT file. They will be cumulative, 
	containing all changes to date for the version indicated. 






Charts:
	IBIS accepts chart files in any of various formats such as 
	bmp, rle, dib, pcx, pic, tif, jpg etc , as well as Maptech .kap
	and MapTech .pcx files. And with 3.0, DRG/Geotiff files.
	You can scan your own charts in any of various formats if you 
	have access to a flat bed scanner just so long as you don't 
	violate any copyrights.	You can convert other disk or CD charts
	to some compressed format using a graphics package, again with
	the same copyright caution. My advice is to buy the Maptech CD
	for your area which contains quality charts.

GPS hookup:
	Get a PC serial connector from the manufacturer or attach a 
	DE9 or DB25 to the power/data cable per manufacturers specs.
	This is usually wiring the NMEA out to pin 2, the NMEA in to
	pin 3 and the signal ground to pin 5 of a nine pin connector. 
	Although this is not a true RS232 setup it will usually work. 
	Connect the GPS and power it on before launching the program. 
	Some GPS units do not output any NMEA data unless they have a 
	3 or more satelite lock on the signal. Consult the manual.
	If you have problems because the voltage levels are not right 
	you may have to make or buy a signal conditioner of sorts. 
	Some people have had luck using the "MAX232" chip.
