10.1.4.2 Analogue or digital dimmer input
When the XDi-net function is enabled the analogue or digital dimmer level used by an XDi unit will normally also
be shared via XDi-net with all XDi units being part of the same dimmer group and of course connected to the
same CAN bus.
An XDi unit with analogue or digital dimmer input can only control the dimmer group that it is part of via XDi-net.
(Dimmer sharing can be on CAN1, CAN2 or CAN1&2)

Note
Analogue [Yes
3
*] Yes Only one XDi with analogue dimmer and sharing data on XDi-net must
be part of a dimmer group*)
Digital Yes Yes Data is only sent on a change, and several dimmer controllers can be in
the same dimmer group. **)
XDi-net Yes No If “ XDi-net variable data on ” is active , then an XDi unit can receive
dimmer data in the normal XDi-net data format using COBID 0x201 to
0x27F.
If
only “ XDi- net function” is enabled, dimmer data can only be received
using XDi-net format using COBID 0x27F (node 127).
PDO converter [Yes
3
*]
(Synch)
No
(Synch)
All devices on CAN have access to the dimmer data, and they are not
retransmitted in XD-net format.
All devices in the group must therefore use PDO converter instead of
XDi-net. Setup changes in the PDO converter may be synchronised via
CAN.
Front buttons Yes Yes XDi can share the front button dimmer adjustment with other XDi units
in the same dimmer group and on the same CAN bus.
NMEA [Yes
3
*] Yes One XDi can share dimmer data for received via the NMEA DDC dimmer
data sentence. One XDi can in fact control a group it is not part of and it
is even able to control more than one dimmer group if the selected
product profile (PP) supports it and several DDC sentences is available
on different inputs or with different talker ID.
*) Please note that if more than one XDi in a dimmer group shares its analogue dimmer data via CANopen or
XDi-net, then all XDi units in that group will receive different dimmer levels from 2 sources, resulting in a flickering
backlight.
**) The above (*) is not the case with XDi units using the digital dimmer input option, since the dimmer command
can be configured so that it is only sent when there is a change, that happens when the digital input for example
connected to a push-button, is activated.
3 *) The XDi is always able to receive XDi-net data when the XDi-net is active, but data will be overwritten
immediately by the analogue dimmer input value.
The dimmer source setup menu is only available if the selected source has parameters that may be changed via
menu.
10.1.4.3 Digital dimmer source setup
Requires a DX1 module to be mounted on the XDi at the specified slot.
