Operating the AM-4 with GPS
Now that you have your playlist file with the GPS coordinates, you can use it in the
AM-4. Here’s how.
Make sure that the AM-4 GPS Mode DIP switch is ON. It’s DIP Switch #4, and it
should be in the down position to turn it ON.
Install the Compact Flash card that contains the playlist you prepared in the previous
section. Make sure that it also contains all of the sounds referenced in the playlist.
Connect the GPS Receiver (mouse) to the GPS Harness Kit that came with your AM-
4 GPS, and connect the other end of the harness to the corresponding input jacks on
the AM-4.
The AM-4 is compatible
with any serial GPS
receiver which outputs a
NMEA-0183 data
stream at default 4800
baud. You can change
the baud rate using the
BR command in your
GPS playlist.
The AM-4 will steadily
blink the Green LED
whenever a valid GPS
input is detected.
The LED will blink RED
while the GPS sensor is
acquiring GPS satellite
data.
The diagram below shows the proper connection using the Alcorn McBride GPS Kit.
Place the GPS sensor on top of the vehicle or other position that the GPS sensor
manufacturer recommends.
Connect the AM-4 audio output. If you have the built-in amplifier module option
installed you can just connect up speakers, otherwise connect an amplifier and
speakers to the line-level (RCA) outputs. Turn up the volume about half-way to start
(you can adjust it later).
Connect the AM-4 to your vehicle power. The AM-4 can accept 10V to 24 VDC.
The “cigarette lighter” outlet found in most vehicles works very well.
