View of AS-i bus image. Each LED 1 to 31 corresponds to an extended address setting slave address on the bus.
  • LED on: slave present
  • LED off: slave not expected and not detected.
  • LED flashes rapidly: peripheral fault on slave.
  • LED flashing slowly: configuration fault on slave.
Diagnostics example with 5 slaves addressed at 1, 4, 10, 11, 20:
In brief :
  • LEDs for slaves 1, 4, 10, 20 are lit, therefore these slaves are active,
  • slave 11's LED is flashing, so it is faulty,
  • the other LEDs are off because no slaves are expected or detected at these addresses.
