LED I-x / O-x yellow: input / output switched
LED PWR green: AS-i voltage supply OK
LED AUX green: External voltage supply (AUX) o.k.
LED FAULT red is lit: AS-i communication error, slave does not participate
in the "normal" exchange of data, e.g. slave address
0.
LED FAULT red flashes: Periphery fault, e.g. sensor supply overloaded or
shorted, is signalled to the AS-i master
(version 2.1 or higher).
