Function / Parameter / Value
001 … 512 DMX address of SPM-12 controller
610
SPM-12 work as without DMX-512 signal - active codes 630 ... 635
611
Outputs work Q1-Q12 in PWM mode:
DMX = 0..255 – Q = PWM 0..100%
612
Outputs work Q1-Q12 in DC mode:
DMX = 0..127 - Q = OFF / DMX = 128..255 - Q = ON
620
DIMMER OFF – function DIMMER is turn off
621
DIMMER ON 1 – function DIMMER is active – 0=min 255=max brightness
622
DIMMER ON 2 – function DIMMER is active – 0=max 255=min brightness
630
No reaction for lack of DMX signal – keeping the last value of outputs Q1-Q12
631
After lack of DMX signal – display effect
632
After lack of DMX signal – turn off all of outputs: Q1-Q12 = OFF
633
After lack of DMX signal – 20% PWM signals on Q1-Q12
634
After lack of DMX signal – 50% PWM signals on Q1-Q12
635
After lack of DMX signal – turn on all of outputs: Q1-Q12 = ON
2.3. Description of configuration codes of SPM-12.
Basic steering codes which need to be set-in to SPM-12 controller is the address of DMX
controller, it means one code form range
001 to 512
. When user enter any code from 001 to
512 it will cause automatic change the previous value form this range and memorize new
address od DMX in memory controller.
DMX address indicate number of channel in steering signal of DMX-512, from where the
steering datas of outputs Q1-Q12 are collect. The controller’s Q1-Q12 outputs will be reacting
on the values from DMX channels
numbered sequentially from
address DMX
to
address DMX + 11.
Second important parameter is the manner of output’s work Q1-Q12.
These outputs can be configured to work in PWM mode –
code 611
or in bistable DC status
(ON/OFF) –
code 612
.
In PWM mode, the outputs Q1-Q12 PWM waveforms are generated by filling proportional to
the value of DMX channel corresponding to output:
- PWM = 0..100% of the value of DMX channel = 0..255
In bistable mode DC (ON/OFF) outputs Q1-Q12 have only two states:
- OFF - turn off, when DMX value of output steering channels is from 0 to 127 range
- ON - turn on, when DMX value of output steering channels is from 128 to 255 range
After enter the
code 610
the SPM-12 will not react on DMX-512 signal even when this
signal pass on in DMX+ and DMX- inputs. Reaction of SPM-12 controller will be the same
as in lack of DMX-512 signal on inputs – see description codes 630...635.
