Projector DMX start address selection
In order for the controller like Elektralite’s CP10xt to control each MY 250Ì it has to know where it is in the
daisy chain of DMX. To do this all MY150s 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 250Ì uses 14 channels of DMX. Those channels control the features of MY 250Ì. 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: Iris movement with in built effects engine for iris.
CHANNEL13: auto program control + lamp on, motor reset and lamp switch off.
CHANNEL14: pan fine.
CHANNEL15: tilt fine.
So if we start with the first
MY 250Ì its first channel is 1. So we refer to it as having a starter address of 1.
The second MY 250Ì will then have its first channel or starter address at channel 17.
The third MY 250Ì will then have its first channel or starter address at channel 33, the fourth MY 250Ì will start
on 049 and so on. Now if you want two MY 250Ìs 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 250Ìs you have on the same starter
address
If you just bought four MY 250Ì 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 MY250Ìs.
If you have another controller, then you will have to set it’s starter addresses for each
MY 250Ì before you will
be able to control any MY 250Ì.
Tips & Tricks
1. If you change the address on MY 250Ì it may appear not to have accepted that address. Turn MY 250Ì
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 250Ì, if it is receiving data, the display will show “A.001” or “A.017” or whatever
the address is for MY 250Ì. If there is still no data getting to MY 250Ì, then run a cable directly from the
controller to the fixture.
