Dimmer
Figure 48
Individual Button - Dimmer.
The (alternating) switch orders will be sent through the “
[Btn] [Xn] Light - On/Off
” one-
bit object, while the (alternating) increase/decrease/stop orders will be through the
“
[Btn] [Xn] Light - Dimming
” four-bit object.
The first one has the
write
flag enabled so it can receive feedback from the dimmer
about the on/off status. Similarly, the “
[Btn] [Xn] Light Dimming (Status)
” one-byte
object can be linked to the light level status object of the dimmer (in fact, this object is
only intended to receive values from the bus, not to send them). As explained in 2.3.4,
the alternation of the on/off and step requests will be conditioned to these statuses, to
prevent sending ineffective requests.
The parameters for this function are:
Step
: defines the dimming step (“100%”, “50%”, “25%”, “12.5%”, “6.25%”,
“3.1%” or “1.5%”) to be sent (through “
[Btn] [Xn] Light - Dimming
”) to the
light dimmer with every long press.
Note
:
since dimmers typically do not apply the new light level immediately
(i.e., the step is performed progressively) and since TMD-Display sends an
order to interrupt the step dimming once the user releases the button, it is
advisable to configure a step of 100%. This way, the user can perform any
dimming step by simply leaving the button pressed and then releasing it,
without needing to make successive button presses
.
LED illumination control
: analogous to the homonymous parameter for all
the above functions (see previous pages). The options in this case are
“Regular”, “State dependent” and “Dedicated object”.
