The front LED
This multi-purpose LED informs about the actual state of data communication, using different
blinking sequences. With normal communication, this LED lights all the time. Where
communication problems appear, the meaning of different blinking sequences is explained by

Transmission details
The unit transmits the data by SDO (Service Data Object) Write Request and awaits a
corresponding Write Response within the next 2.5sec (Timeout). It operates similar to a
CANopen master (But it is no CANopen master!). No other CANopen communication objects
are supported, except the SDOs.
