7- DMX SIGNAL CONNECTION
The unit operates using a digital DMX 512 (1990) signal. Connection between the
control box and the projector or between projectors must be carried out using a two pair
screened ø0.5 mm cable and a CANNON
.
Ensure that all conductors are isolated from one another and from the metal plug
housing.
The plug housing must be isolated. Connect the control box signal to the DMX IN
projector plug and connect it to the next projector by connecting the DMX OUT plug on
the first projector to the DMX IN plug on the second.In this way, all the projectors are
cascade connected.
NB.
- DMX signal not present
- DMX address not valid
- DMX reception problem
Install when the signal wire has to be put in long distances or where there are electrical
disturbments for example in a disco, concert, theater etc we advice to use a dmx terminal.
the dmx terminal or even more a canon xrl-5 connected with a resistance to 120 ohm
between 2 and 3 the resistance is put in the plug of the dmx of the last device that has been
linked as shown following.
The standard configuration of the XR250WASH is with XLR 5 pole connection.
To convert to an XLR 3 pole configuration proceed as follows:
1) Unscrew the external cover (photo 1).
