This file should help anyone who wishes to, upload waypoints from, or
to download from, a Micrologic Admiral GPS.  I use this as I have
better things than to enter all the waypoints each time I get the
software upgraded.  Needless to say I do not guarantee anything but
this is exactly what I use with my Micrologic Admiral GPS.  If you are
not happy with a soldering iron take it to someone who is capable.

I bought an extra power I/O cable for the GPS ($38.69, Boulet Lemlin, Quebec
City, 1-800-463-4571, 418-681-5655) so that I could take the
GPS home and connect it to my computer.  I also bought a DB25
female connector and shell (try Radio Shack).

The power I/O cable has six wires.  Connect as follows:

Orange    Connect to (+) 12 V DC power
Black     Connect to (-) 12 V DC ground AND PIN 7 OF DB25
Grey      Connect to pin 2 of DB25
Green     Connect to pin 3 of DB25
White    Connect to pin 7 of DB25
Yellow    Not used

Connect pins 4, 5 and 8 together.
Connect pins 6 to 20.

I use a 12 V power supply but a 12 V battery will work.  I use
banana plugs to connect to the power supply.   It should be possible
to put the black wire and the jumper wire into the black banana plug.
If it is not possible to get both wires into pin 7 splice the jumper
wire onto the white wire going to pin 7.

Connect the power I/O cable to: the Admiral using J2 (closest to the
middle), power source and the DB25 to your computer.  You may need a
modem cable if you can not get near your serial port.  Turn the power
on and turn on your GPS.  Hopefully everything is now working.  You do
not need a fix to transfer waypoints nor do you need the antenna
connected.

If you have a 9 pin serial port then you will have to translate the
pin assignments.  I believe pin 7 above becomes 5, pins 2 and 3
remain the same, connect 7 to 8, and connect 6 to 4.  Please verify
as I do not have access to verify these pin assignments.

For a waypoint upload.  On the second setup screen, set serial port 1
to WPxUPLOAD, DO NOT PRESS ENTER YET!

The WP-UPLOAD can be used if no description of waypoints.  Your file
will contain lines like the following if you use WP-UPLOAD:

$GPWPL,4849.65,N,06428.53,W,0001*54
$GPWPL,4849.70,N,06428.50,W,0002*50

Set up your communications program for 4800 baud, 8 data bits, 1
stop bit, no parity.  Start ASCII download.
NOW PRESS ENTER on the Admiral GPS.

You should obtain a file with lines like the following two lines.
$PMCLF,4849.655,N,06428.532,W,0001,MARINA BERTH    ,18:34,010295,10//0*20
$PMCLF,4849.700,N,06428.500,W,0002,MARINA ENTRANCE ,18:49,010295,10//0*44
       
                                                      
Code     Latitude   Longitude  Way     Description   Time   Date

waypoint                       Number

To download waypoints create an ASCII file as below, with the
following format.  Each line must start in column one and commence
with $aaWPL.  Set you communications program as above but set up ASCII
download line pacing to at least 2 seconds.  I have used 25/10 ths and
30/10 ths of a second line pacing with TELIX.
