LED Status Indicator

The LED status indicator is used to determine the OCTO MK2’s current state. Each state is as follows:

Identify/Reset Button

The Identify/Reset button on the OCTO MK2 can be used to either:

• Identify pixels connection
  When the button is pressed in standard operation, all 8 output universes are set to output the highest value (255) for 10 seconds before resuming their previous state. This is a good practical test to ensure all outputs are connected and working as intended. This function can also be achieved from our intuitive web interface under Home Tab.

• Reset the OCTO MK2 (Refer to the ‘Reset to Factory Defaults’ section of this document).

Out of the Box

The OCTO MK2 will be set to a DHCP IP address as default. If the DHCP server is slow to respond, or your network does not have a DHCP server, the OCTO MK2 will fall back to 192.168.0.10 as default. By default, the OCTO MK2 will convert 4 universes of Art-Net to the WS2812B protocol on each of the OCTO MK2’s Phoenix Connector ports. Both ports will output Art-Net universes 0 to 3.

Networking

The OCTO MK2 can either be configured to be a DHCP or Static IP address.

DHCP: On power up and with DHCP enabled, if the OCTO MK2 is on a network with a device/router with a DHCP server, the OCTO MK2 will request an IP address from the server. If the DHCP server is slow to respond, or your network does not have a DHCP server, the OCTO MK2 will fall back to the IP address 192.168.0.10 and netmask 255.255.255.0. If a DHCP address is provided, this can be used to communicate with the OCTO MK2.

Static IP: By default (out of the box) the Static IP address will be 192.168.0.10. If the OCTO MK2 has DHCP disabled, the Static IP address given to the device will become the IP address to communicate with the OCTO MK2. The Static IP address will change from the default once it’s modified in the web interface. Please note down the Static IP address after setting.

Note: When configuring multiple OCTO MK2’s on a Static network; to avoid IP conflicts, ENTTEC recommends connecting one device at a time to the network and configuring an IP.

• If using DHCP as your IP addressing method, ENTTEC recommends the use of the sACN Multicast, or Art-Net Broadcast. This will ensure that your OCTO MK2 continues to receive data if the DHCP server changes it’s IP address.
• ENTTEC does not recommend unicasting data to a device with its IP address set through DHCP server on long term installations.

Web Interface

Configuring the OCTO MK2 is done through a web interface which can be brought up on any modern web browser.
Note: A Chromium based browser (i.e. Google Chrome) is recommended for accessing the OCTO MK2’s web interface.
Note: As the OCTO MK2 is hosting a web server on the local network and does not feature an SSL Certificate (used to secure online content), the web browser will display the ‘Not secure’ warning, this is to be expected.
Identified IP address: If you are aware of the OCTO MK2’s IP address (either DHCP or Static), then the address can be typed directly into the web browsers URL field.
Unidentified IP address: If you are not aware of the OCTO MK2’s IP address (either DHCP or Static) the following discovery methods can be used on a local network to discover devices:

• ENTTEC EMU software for Windows and MacOS (support Mac OSX 10.13 or later), which will Discover  ENTTEC devices on the Local Area Network, displaying their IP addresses before opting to Configure the device, opening the Web Interface.
• An IP scanning software application (i.e. Angry IP Scanner) can be run on the local network to return a list of active devices on a local network.
• Devices can be discovered using Art Poll (i.e. DMX Workshop if set to use Art-Net).
• The device default IP address 192.168.0.10 will be printed on the physical label on the rear of the product.

Note: The eDMX protocols, the controller and the device used to configure the OCTO MK2 must be on the same Local Area Network (LAN) and be within the same IP address range as the OCTO MK2. For example, if your OCTO MK2 is on Static IP address 192.168.0.10 (Default), then your computer should be set to something such as 192.168.0.20. It is also recommended that all devices Subnet Mask are the same across your network.

Node Name: Change Node Name for identification.
DHCP: Enabled by default. When enabled, the DHCP server on the network is expected to automatically provide the IP address to the OCTO MK2. When DHCP enabled but there is no DHCP server or slow to response, the OCTO MK2 will fall back to 192.168.0.10.
IP Address / NetMask / Gateway: These are used to set when DHCP is disabled. These options set the Static IP address, Netmask and Gateway IP settings which should be compatible with other devices on the network.
LED Protocol: Select the SPI protocol from the drop-down list or set a custom value that matches the Pixels which the OCTO MK2 will control.
The OCTO MK2 provides more than 20 output pixel protocols listed below.

• Node Name: Change Node Name for identification.

• LED Protocol: Select the SPI protocol from the drop-down list or set a custom value that matches the Pixels which the OCTO MK2 will control.
  The OCTO MK2 provides more than 20 output pixel protocols listed below.

Each port can have a different pixel output protocol. The pixel protocols selected can be output directly to your pixel fixtures.
The OCTO MK2 also features custom voltage timing to most of the pixel protocols configurable in each port settings individually. The custom voltage timing of the chosen pixel protocol can be adjusted according to its datasheet. Visit ENTTEC website to view the ‘OCTO MK2 Custom Protocol Creation Guide’ document if your SPI protocol is not listed.)
The adjustable custom values are:

• Bit 0 High Time: The voltage high time required to indicate code 0, also known as T0H.
• Bit 1 High Time: The voltage high time required to indicate code 1, also known as T1H.
• Overall Bit Time: The total voltage time for a single bit which can be calculated from TH+TL.
• Reset Time: The total voltage low time required to reset the data transmission between each data batch.
• Example: The information required from WS2812B datasheet is the Data Transfer Time as below:
• Please test on your pixel fixture for the optimal transmission time among the range according to the datasheet.
  • 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 can be found at www.enttec.com.
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 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)
  Save Settings: All changes must be saved to take effect. The OCTO MK2 takes up-to 10 seconds to save.
  Reset to Defaults: This button allows the OCTO MK2 reset back to factory default via web interface. Please refer to the ‘Reset to Factory Defaults’ section of this document.
  Reboot: Please allow up-to 10 seconds for the device to reboot. When the web interface page refreshes the OCTO MK2 is ready.
