Troubleshooting Guide / FAQ
Q:
Do you have a basic checklist I can go by in order to figure out what’s wrong?
A:
Here’s a checklist we have compiled of typical things you can check to make sure all the bases
are covered:
•
Is the unit plugged in? (bear with us)
•
Does the unit have a Compact Flash card in it at all? (remove the front metal plate &
check)
•
Is the Compact Flash card pressed in all the way?
•
Validate you’ve used the speaker cables/line level cables somewhere else successfully.
Verify your speakers work, etc…
•
If you are using a serial cable, is it straight through (not null modem)?
•
Are your audio files valid? Check them on your PC using Adobe Audition (formerly
CoolEdit, Windows Media Player or another audio player application.
•
Are your file name formats valid? See the
File Names
section to be sure.
•
If copying files from your PC, did you use DOS? If you used windows, save the audio
files somewhere. Reformat the card in the AM-4. Follow the list of steps in the
Copying
Files
section
•
Take every other piece of control equipment away from the unit, making it stand alone
until you get it running. Try to make it operate now either with contact closures (paper
clips will work) or serial commands from a laptop or PC.
•
If the unit shows
no response
to serial messages typed by hand or from another system:
o
Have you validated you are communicating through the serial port correctly?
Chosen the right PC comm. port? Using 9600, 8,N,1? If you want to validate the
comm. port is right, use a paperclip to short together pins 2 and 3 on your
computer’s serial port cable. It should echo back to you the keys you type from
a terminal emulator like Hyperterminal.
o
Are you using the correct commands listed in the Advanced Serial Protocol
Section? Can you get a version number from the box by using a terminal
emulator, or AMI Terminal?
•
Is the Compact Flash Card damaged? Do you have a second Compact Flash card you can
temporarily use to make sure the Compact Flash Card isn’t just damaged? Go through the
file copying process with the new Compact Flash Card, and try to play the file.
•
Is the unit damaged? If you can put another AM-4 Digital Audio Machine in the circuit,
you can rule out the possibilities of a damaged unit.
Remember to use the same
Compact Flash card.
Q:
My AM-4 is not triggering when I pass through my programmed GPS points.
A:
Here’s a list of things to check when operating in GPS mode:
•
Make sure that you’re using only MP3 files. The AM-4 does not support the playback of
WAV files in GPS mode.
•
Have you named the GPS playlist correctly. It should be named PLY00000.GPS to start
automatically.
•
Is your tolerance set too low? Try to move very slowly through the programmed points at
first to see if you get a trigger. If the trigger fails at higher speeds then you might need to
set the tolerance higher.
