4.7.8.1 Stop scan - manual select
To see what is actually selected, highlight “Stop scan – manual select…” and press OK.
You will then get this picture:
RED dot
means that no external sources are available, in this case for the dimmer data group.
YELLOW dot
means that sources are available for some data in the group, but it should be checked. Some data
types may need manual selection, or some may be missing.
GREEN dot
means that all data types in this group have been assigned a source.
We can now look through the automatic selection and check that needed data has a source assigned:
4.7.8.2 DIMMER
The dimmer group is red on the above display. That is because the XDi-N does not receive any NMEA DDC
sentences to control the dimmer. If we press OK on the dimmer group, it will open and we can see that no NMEA
sources are available.
In this case, it doesn’t matter since we have chosen a product profile (PP) where dimming is controlled by the front
buttons.
If you want to use NMEA to control the dimmer level you must select a PP that supports NMEA dimming.
