Projector DMX start address selection
In order for the controller like
Elektralite’s CP10xt
to control each
MY 250
it has to know where it is in the daisy
chain of DMX. To do this all
MY150
s have to be set to a start address. To understand the concept of a starter
address we also have to understand the concept of channels and the features those channels have.
MY 250
uses 14 channels of DMX. Those channels control the features of
MY 250
. They are as follows:-
CHANNEL 1 :
select one of the 9 colors, color cycle or rainbow effect
CHANNEL 2 :
select one of the 6 gobo’s + open or gobo cycle+ gobo shake
CHANNEL 3 :
select gobo rotation speed and direction
CHANNEL 4 :
select one of the 7 gobos + open or gobo cycle + gobo shake.
CHANNEL 5 :
pan movement (max. 630°)
CHANNEL 6 :
tilt movement (max. 265°)
CHANNEL 7 :
speed pan/tilt movement, blackout selection
CHANNEL 8 :
select prism or normal lens + prism rotation and speed. Also 16 prism macros.
CHANNEL 9 :
focus
CHANNEL10:
select strobe (0 – 15 flashes per second). Both linear & random strobe.
CHANNEL11:
dimmer 0-100%. (N.B. this channel only works when channel 10 is between dmx level 32-63).
CHANNEL12:
auto program c lamp on, motor reset and lamp switch off.
CHANNEL13:
pan fine.
CHANNEL14:
tilt fine.
So if we start with the first
MY 250
its first channel is 1. So we refer to it as having a starter address of 1.
The second
MY 250
will then have its first channel or starter address at channel 17.
The third
MY 250
will then have its first channel or starter address at channel 33, the fourth
MY 250
will start on
049 and so on. Now if you want two
MY 250s
to be always the same in color, movement and so on then you
can set both of them to the same address. In this way you can create groups of fixtures having the same effects
happen at the same time. There is no restriction on how many
MY 250s
you have on the same starter address
If you just bought four MY 250 and it came with an Elektralite CP10xt, the starter addresses in the
CP10xt have already been set. All you have to do is set the starter addresses on the four MY250s.
If you have another controller, then you will have to set it’s starter addresses for each
MY 250
before you will be
able to control any
MY 250
Tips & Tricks
1. If you change the address on
MY 250
it may appear not to have accepted that address. Turn
MY 250
off wait until the lamp cools down (remember it is not a hot re-strike lamp) and then turn it back on
again.
2. When you turn on
MY 250
, if it is receiving data, the display will show “A.001” or “A.017” or whatever
the address is for
MY 250
. If there is still no data getting to
MY 250
,
then run a cable directly from the
controller to the fixture.
