	Lowrance supplement to the GPSMan Documentation.
	***********************************************

	1)  GPS receiver setup.

	Follow the instructions given in your Lowrance manual. Set the
	Com Port to 19200 bps, 8 data bits and no parity. Use the
	correct Lowrance accessory data cable for your particular unit.
  
	2)  Getting Waypoints from the GPS unit.

	The Lowrance GlobalNav 212 receiver stores up to 999 Waypoints
	internally. GPSMan downloads all 999 whether valid or not. The
	indices of invalid (Unallocated) Waypoints are listed by 
	GPSMan and unused index numbers allocated when new Routes are 
	made or new Waypoints are created by GPSMan. For this reason all 
	Waypoints and Routes are read into buffers on initialisation of 
	the serial interface. This read operation can take nearly two 
	minutes at 19200 baud, please be patient.

	The buffer mentioned above is not read into GPSMan memory until 
	the "Get WPoint" and "Get Route" buttons in the GPSMan "GPS 
	Receiver" window are clicked. This should be done before creating 
	any Waypoints or Routes with GPSMan, all Waypoints and/or Routes 
	should then be saved to the receiver before exiting GPSMan.

	3)  Waypoint Names.

	GPSMan is now able to handle Waypoint names containing spaces, so
	spaces are no longer automatically deleted.

	Note that the ASCII characters ".", "'", "(", "/", ")" and "-" can
	also occur in Lowrance along with " ".	

	4)  Lowrance Trails.

	The terms "trail" and "track" are used interchangeably by GPSMan.

	5)  Time Offset.

	GPSMan for Lowrance does not use the "Time Offset" setting under
	the options menu. However it is recommended that this variable
	be correctly set, for compatibility reasons. All times are displayed
	in local time, not UTC.

 
	This program uses the Lowrance LSI 100 interface protocol rev 1.1.
	Copies of this protocol are available from www.lowrance.com.
