SPM-12 – controller
DMX-512 – 12 OUT DC / PWM
7
Codes
621
and
622
activates function DIMMER available only in PWM mode, usually
used for steering the LED brightness connected to outputs Q1- Q12.
DIMMER function allows for brightness regulation of all outputs at the same time by using
only one DMX-512 channel, and activate additional 13 DMX channel with address
address DMX + 12
, where
address DMX
is code from 001..512 range – see above.
When the signal DMX-512 increased for code
621
, the brightness of LED will also
increased.
When the signal DMX-512 increased for code
622
, the brightness of LED will decreased.
If the function DIMMER is not necessary code
620
need to be enter to turn it off and
release the 13 channel DMX.
Codes
630 to 635
settle the way of reaction SPM-12 controller for lack of DMX-512
signal. One second after lack of DMX-512 signal take place the reaction determine by the
enter code.
The re-apperance of DMX-512 signal at the inputs DMX+ and DMX- an immediate
return to the control outputs Q1-Q12 data from the received signal DMX-512 (except when
code 610 is entered forcing the driver SPM-12 to work without the DMX signal).
The way of response of SPM-12 driver for DMX signal loss for the individual codes is
described in Table 1.
The demonstration effect for the code
631
is smoothly dimming and lightening of LEDs
connected to the outputs Q1-Q12 in an alternate driver for the outputs of odd and even
numbers, and with the average brightness LEDs.
Some combinations of input control codes are especially noteworthy, eg:
- Entering codes 610 and 630 will continuous disable the state outputs Q1-Q12 (regardless of
DMX-512 signal), because after the reboot power all outputs of controller SPM-12 are reset,
code 630 does not change the output status, and the code 610 prevents receiving
the DMX-512 signal;
- Entering codes 610 and 633 will generate a continuous PWM signal at the outputs of the
fulfillment of 20%, eg dim the LEDs connected to the outputs Q1-Q12;
- Entering codes 612 forcing the work of
Q1-Q12 in DC
mode should not be link with 631,
633, 634 codes, because in case of loss of DMX-512 signal at the outputs of the PWM
waveform will appear, which may cause malfunction of receivers designed to control DC
(ON / OFF), such as relay coils;
2.4. Example configuration of the controller SPM-12:
001 - address DMX = 1 (address of output Q1 = 1, address of output Q12 = 12)
611 - outputs work Q1-Q12 in PWM mode
621 - DIMMER active on channel number 13th - DMX
631 - display effect is active while lack of DMX-512 signal
These 4 codes need to be set in into SPM-12 to ensure work in requested way.
Sequence of entering the codes is optional.
