Dimmer function:
defines the function of the two digital inputs used for dimmer. Selections are UP/Down or
UP/Down/Colour. The functions are described in the DX1 section.
Detection:
defines how the signal on the digital input must
be detected, either trigger the function on a “Low to
High” transition or on a “High to Low” transition. Default is low to high equal to detection when a serial connected
contact is pushed to close the circuit.
Update rate on XDi-net
: is the repetition rate of dimmer messages being sent on XDi-net (CAN).
The DX1 has a setting called “On change”. This setting should be selected if more than one XDi controls the
dimmer group in parallel.
The analogue module does not have the setting “On change,” and therefore only one XDi with analogue input can
control a dimmer group.
Use CAN interface:
if a CAN port is selected, dimmer data is shared on the selected port(s) using XDi-net protocol
and at the repetition rated above.
The settings are: NO, CAN1, CAN2 or CAN1&2

Analogue dimmer source setup
For analogue dimmer input, an AX 1 extension module must be mounted in the extension slot specified in the
product profile, for example Slot1.
In the example below, the XDi is set up to be part of dimmer group 1 and therefore all the dimmer settings,
including the dimmer source setup, relates to this dimmer group.
