Time to look at the DSD440 controller board...
The green leds ( 1 and 9 ) should be on.
Leds 2-3-4 are status leds :
Led 2 : Controller waiting for interface.
Led 3 : controller writing
Led 4 : controller reading

Leds 5 to 8 should be off : they represent a binary errorcode.
 I can look them up for you if required...
