Each
iSpot 575
utilises
20
or
21
channels of DMX 512 signal for complete control. The number of channels varies
depending on the mode (
Mode
) selected;
Mod1
(20 channels),
Mod2
(21 channels). The additional channel offers further
functions (for more details see paragraph
12. DMX 512 signal functions
)
DMX coding
To ensure that each projector accesses the correct signal, it is necessary to correctly address each fixture. Any number
between 1 and 493 can be generated via the multifunction panel of the
iSpot 575
.
This procedure must be carried out on every
iSpot 575
being used.
When powered up initially, each projector will show
A001
which indicates
DMX address 1
; a projector thus addressed
will respond to commands on channel
1
to
20
from
DMX 512 controller
. A second unit should be addresses as
21
, a
third as
41
and so on until the final
iSpot 575
has been addressed.
Altering DMX addresses
1) Press the
+
or
-
button until the display shows the
DMX
required, the characters in the display panel will flash to indicate
that the selection is not stored in memory.
2) Press the
enter
button to confirm your selection; the display will stop flashing and the projector will now respond to the
new DMX address.
3) To better understand the function of each channel, we refer you to section 12 “Control channel functions from a
DMX
512
controller”.
Important Note
: Keeping the
+
or
-
button pressed will cause the display to alter at increased speed, allowing a faster
selection to be effected.
By pressing the
–
button, you may inadvertently select a DMX address which is not being communicated to the fixture by
the controller, for example 500. If this is the case, the display will slow the data reception, (since it does not exist), and you
will note that it is slow to respond to your commands (for example altering an address or requesting or confirming a reset).
You may solve this problem by either sending data to this address, or by altering the incorrect DMX setting of the
iSpot
575
in question.
