I have recently connected the FlightSoft Professional Flight
Planning and Moving Map (DOS - $178) software to a laptop and a
"black box" GPS that uses the NMEA-0813 standard.  It worked like
a charm so I thought I would post the "read.me" file that came
with the software, FYI.  I have no connection with FS-PRO except
that I like the price performance of the software...

The Moving Map connects to your loran/GPS via a standard RS-232 serial cable.
The Moving Map only reads the loran/GPS (it doesn't send anything back), so
only two leads must be connected.  The Signal pin from the loran/GPS (sometimes
called "Data Out") must be connected to the "Data In" pin of the computer's
serial adapter, and the "Signal Ground" pin from the loran/GPS must be
connected to the computer's "Signal Ground" pin.  The pin numbers, and the
"Locator Group" setting for the Moving Map, are shown in the following table.
If your loran or GPS isn't listed, please let us know.

We recommend that a shielded cable be used for the connection to avoid signal-
loss and interference problems.

If your loran or GPS unit is not listed above, contact RMS Technology.  We can
send a test disk that will gather the information needed for us to make an
adaptation in the Moving Map, if necessary.
