Is there any way to check if the MP3 player is working ?
Yes!, First of all, when you power up the player, the LED will flash then a few seconds later, will fast blink while searching for song files. If after about a minute, the LED is still blinking, then a problem with the FAT32 filesystem, missing folders or missing files exists. You can make your MP3 play songs without being hooked up to the wallbox hub. In the DSUB 9-Pin connector, connect pin 2 to pin 3. This will force your player into “auto mode” which causes it to play all the songs on your hard drive. If you’re familiar with using the computers serial port and HyperTerminal, then you can set HyperTerminal to your active com port, 9600 baud and no flow control. Connect pins 2/3 of the MP3 connector to pin 2 on your computers’ 9-pin serial port connector and pin 5 to pin 5. With HyperTerminal running, you should see 1-43-234 56789AB (then songs begin to play) The first line of 6 digits are for internal self tests, the second line of digits are disk related: 5= Starting up HDD 6= Chec
