6.5. Diagnostic ..................................................................
6.5.1. Level 1
Level 1 diagnostics runs automatically when the soundCUE is powered on or after reset. It checks
internal microcontroller circuitry. When the tests are running properly then the DATA O.K. LED starts
blinking (by the Morse signal OK). After that the soundCUE is ready for normal operation.
6.5.2. Level 2
Pressing the TEST button when the interface is already powered causes the start of the Level 2
testing.
It sets
• Main volume 0 dB, channel volume 0 dB, bass 0 dB, treble 0 dB
• In period of about 2 seconds starts the testing cycle. In this cycle are all outputs switched to
input A for about 1 second then to B, C, D inputs and to microphone input.
• The cycle will stop when TEST button is released and both sound processors will return to the
same status like before starting level 2.
6.5.3. Level 3
When the TEST button is pressed on while the interface power is switched on or you keep the TEST
and RESET buttons pressed, release the RESET button and keep the TEST button pressed for about
3 seconds. After approx. 3 seconds you can release it.
Connect the diagnostic adapter (connector DB-9-male which makes shortage between pins 2 and 3)
to DATA IN. Now the interface is sending the message itself to DATA OUT, does receive it itself at
DATA IN and carries out the command.
Now the same diagnostic sequence runs
• Main volume 0 dB, channel volume 0 dB, bass 0 dB, treble 0 dB
• In period of about 1 second starts the testing cycle. In this cycle are all outputs switched to
input A for about 2 seconds then to B, C, D and to microphone input.
Level 3 allows check the same functions like level 2 plus the CUEring interfacing circuitry of the
soundCUE.
It can be stopped only by reset.
