Configuring the device for DMX control

About DMX

The Q-8 can be controlled 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.
The cables can be daisy chained between the fixtures, and up to 32 fixtures can be connected on the same DMX link. Up to 300
meters (1000ft.) of cable is achievable with high quality DMX cables. In installations with standard fixtures, remember that all DMX
links must be terminated in the last fixture 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.
• The last fixture must always be fitted with a DMX termination plug to the fixture's DMX out.

DMX Start address

The Q-8 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 Q-8 must be assigned its own DMX start address. For example, if the first standard Q-8 is set to 27ch
CTC DMX mode with a start DMX address of 113, the following Q-8 in the DMX chain should then be set to a DMX address of 140.
As the first fixture uses all the first 27 DMX channels, including channel 113, the next available channel is 140 (113+27=140 >> 140).
If two or more fixtures of the same type have the same DMX address, and set to the same mode, they will behave identically.
Incorrect settings will result in unpredictable responses from the lighting controller. Address sharing can be useful for diagnostic
purposes and symmetrical control.
NOTE!!
When using power link connection, make sure the maximum power capacity is not exceeded in order to avoid short-
circuit and damaging of the fixture.

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.
For your convenience, the next available DMX address is displayed to the right. Note that
channel spacing is determined by the number of channels of the DMX mode. See the
instructions on how to use the display panel in "Configuring the device" on page 8
The Q-8 also offers the option to set the DMX address through RDM.
