▪
Example
:
The information required from WS2812B datasheet is the Data Transfer Time as below:
▪
Note:
APA102 and 9PDOT are not compatible with Custom Timing due to protocol data and timing
structure.
Colour Order
: Configure how RGBW colours are mapped to pixels.
Mapped Pixels
: Define the number of mapped pixels.
Global Brightness
: This is a function of protocols TM1814 and APA-102 that sets their maximum brightness
for the tape without hindering the DMX range available.
DMX Protocol (Input)
: Choose between Art-Net, sACN, ESP and KiNet as the input eDMX protocol.
Output Universes
The OCTO MK2 converts up to four universes of DMX over Ethernet to pixel data per output. Both outputs
can be specified to use the same universes, e.g., both outputs use universe 1, 2, 3 and 4.
Each output can also be specified to use its own individual group of universes, e.g., output 1 uses universes
100, 101, 102 and 103 however output 2 uses 1, 2, 3 and 4.
Only the first universe can be specified; the remaining universes, second, third and fourth are automatically
assigned subsequent universes to the first one.
▪
Example:
If the first universe is assigned 9, the second, third and fourth universes will be
automatically assigned 10, 11 and 12.
Art-Net:
Supports Art-NET 1/2/3/4. Each output port can be assigned a universe number in the range 0
to 32767.
sACN:
Outputs can be assigned a universe number in the range 1-63999. Please note the OCTO MK2
supports a maximum of 1 multicast universe with sACN sync. (i.e., all universes set to the same value)
ESP:
Outputs can be assigned a universe number in the range 0-255. More details of the ESP protocol
KiNet:
Outputs can be assigned a universe number in the range 0-65535. Further KiNet configuration can
be achieved through ENTTEC ELM Software.
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 Pixels is set to 10 on an OCTO MK2 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 MK2, the
first 10 LED pixels would respond to it.
▪
Note:
The maximum number of physical LED pixels that can be connected to each port 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 pixels each OCTO MK2 can control.
DMX Start Address (DSA)
Assigns the first DMX channel, this is where the OCTO MK2 will start listening for DMX values within the
universe. 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
