About DMX
The G-1 Beam (POI) 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 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 first channel used to receive data from a DMX control device is known as the DMX start address.
For independent control, each G-1 Beam (POI) must be assigned its own DMX start address. For example, if the first G-1 Beam is set
in 12-channel DMX mode, and have a DMX address of 101, it will use the channels all the channels from 101 to 112. Therefore, the
following G-1 Beam in the DMX chain should then be set to a DMX address of 113 (101+12=113 >> 113), as the first fixture uses all the
first 12 DMX channels.
If two or more devices 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 symmetrical 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. 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
“Configuring the device” on page 13 for instructions on using the display panel.
The G-1 Beam also offers the option to set the DMX address through RDM. See “RDM” on page
23.
NOTE 1: the POI versions are only addressable via Remote Device Management. See “POI
Permanent Outdoor Installation” on page 24. RDM control requires cabled DMX.
