OCTO – 71521

the latest version
Example:
If the first universe is assigned 9, the second, third and fourth universes will be automatically
assigned 10, 11 and 12 as shown in the image below.
Group pixels
This setting allows multiple pixels to be controlled as one ‘virtual pixel’. This reduces the overall
amount of input channels required to control pixel strip or dots.
Example:
When ‘group pixel’ is set to 10 on an OCTO connected to a length of RGB pixel strip, by patching a
single RGB pixel within your control software and sending the values to the OCTO, the first 10 LED’s
would respond to it.
Note:
The maximum number of physical LED pixels that can be connected to each OCTO is 680 (RGB) or 512
(RGBW). When grouping pixels, the number of control channels required is reduced, this function
does not increase the number of physical LED’s each OCTO can control.
DMX start address
Selects DMX channel number, which controls the first pixel. When the universes/output is more than
one, the DMX start address only applies to the first universe.
However, where it applies, a start address offset may result in the split of a pixel. e.g., R channel in
first universe and GB channels in the seconds universe for a RGB LED.
For ease of pixel mapping, ENTTEC recommend offsetting the DMX start address to a number divisible
by the number of channels per pixel. i.e.:
Increments of 3 for RGB (i.e., 1,4,7, 10)
Increments of 4 for RGBW (i.e., 1,5,9,13)
Increments of 6 for RGB-16 bit (i.e., 1,7,13,19)
Increments of 8 for RGBW-16 bits (i.e., 1,9,17,25)
Standalone
Standalone is to be used to create a looping effect that can be played back from the point the OCTO
is powered on. This can also be of use to test the OCTO’s output without the need to send eDMX
data.
Standalone can be activated by clicking on the ‘Use Standalone mode’ button as shown below:
