6.5 DVD Player Control Test
To test the infrared diode and the rest of the system in user mode, install a
music CD in the APEX model 1201 DVD player. Music CDs appear to respond
faster than video CD’s in this CD player.
To test the software, infrared diode and the rest of the ASM520 PC board,
follow these steps:
1. Configure the television and DVD player, following the instructions
provided with the DVD player.
2. On the DVD player, depress the power switch on the left side of the DVD
player to turn it on.
3. On the DVD player, depress the OPEN/CLOSE switch located to the
right of the DVD drawer to open the DVD drawer.
4. Install a music CD in the APEX model 1201 DVD player.
5. Depress the OPEN/CLOSE switch on the DVD player to close the DVD
drawer.
6. Wait for the yellow LED, located on the lower right hand end of the DVD
player, labeled MP3/CD JPEG to illuminate. It can take up to 10 seconds
on this DVD player.
7. Point the ASB520 board with LED D1 toward the DVD player and
depress the POWER switch on the ASB520 PC board to turn the DVD
player off.
8. Verify the yellow MP3/CD JPEG LED turns off.
9. Point the ASB520 board with LED D1 toward the DVD player and again,
press the POWER switch on the ASB520 PC board. In approximately 10
seconds, the MP3/CD JPEG LED will once again illuminate. This delay
is a function of the DVD player and not the controller.
10. Point the ASB520 board with LED D1 toward the DVD player and
depress the PLAY switch on the ASB520 PC board. The first song on
the CD will play.
11. Point the ASB520 board with LED D1 toward the DVD player and
depress the PAUSE switch on the ASB520 PC board. The music will
stop playing.
12. Point the ASB520 board with LED D1 toward the DVD player and
depress the PLAY switch on the ASB520 PC board. The music will
resume at the point it was paused.
13. Point the ASB520 board with LED D1 toward the DVD player and
depress the STOP switch on the ASB520 PC board. The music will stop
playing.
