ABOUT DMX
The i-2 UVA can be controlled by using signals sent by a DMX controller on a number of DMX channels.
DMX is the USITT DMX512-A standard, based on the RS-485 standard. The signal is sent as DMX data from a console
(or a controller) to the fixtures via a shielded twisted pair cable designed for RS-485 devices.
Fixtures can be linked together in a daisy chain. Up to 32 fixtures can be connected to the same DMX link. Up to 300
m (1000ft) of cable is achievable with high quality DMX cables. All DMX links must be terminated by connecting a DMX
termination plug to the last fixture´s 5 pin DMX-out connector.
PLEASE NOTE! STANDARD MICROPHONE CABLE IS NOT SUITABLE FOR TRANSMITTING DMX. UP TO 32 FIXTURES
CAN BE LINKED TO THE SAME DMX CHAIN. ADDITIONAL FIXTURES WILL OVERLOAD THE LINK.
DMX START ADDRESS
The i-2 UVA can be operated in different DMX modes. For any of the modes, the first channel used to receive data from
a DMX control device is known as the DMX start address.
For independent control, each i-2 UVA must be assigned its own DMX start address. For example, if the first i-2 UVA is
set to 2ch 16-bit DMX mode with a start DMX address of 101, the following i-2 UVA in the DMX chain should then be set
to a DMX address of 103. As the first fixture uses the first 2 DMX channels, including channel 101, the next available
channel is 103 (101+2=103).
If two or more i-2 UVA have the same DMX start address, they will behave identically. Incorrect settings will result in
unpredictable responses from the lighting controller. Address sharing can be useful for diagnostic purposes and sym
-
metrical control.
SET/EDIT DMX ADDRESS
The DMX address is shown on the OLED display in the control panel. To change the address setting, press the up and
down arrows. When the desired address is displayed, press ENTER to save the setting. The next available DMX address
is displayed to the right. Note that channel spacing is de
-
termined by the number of channels of the DMX mode.
See “Configuring the device” on page 13 for instructions
on using the display panel.
The i-2 UVA also offers the option to set the DMX address
through RDM.
PLEASE NOTE! POI VERSIONS ARE ADDRESSABLE VIA
RDM. SEE
