The port LEDs indicate the operating states of the individual ports of the
OSM/ESM. On the OSM/ESM variants with digital inputs, the state of the inputs is
also indicated by the port LEDs. To allow this, the OSMs/ESMs have an additional
display mode. The display mode of the port LEDs can be changed using the
Select/Set button on the front panel of the OSM/ESM allowing all operating states
to be displayed. The current display mode is signaled by the display mode LEDs.
