Networking
The OCTO MK2 can either be configured to use 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 MK2s 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
its IP address.
ENTTEC does not recommend unicasting data to a device with its IP address set through the DHCP server
on long-term installations.
Web Interface
Configuring the OCTO MK2 is done through a web interface that can be brought up on any modern web
browser. A Chromium-based browser (i.e. Google Chrome) is recommended for accessing the OCTO MK2’s
web interface.
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 browser’s 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’s default IP address 192.168.0.10 will be printed on the physical label on the rear of the product.
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.
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.

Custom LED Protocol: Tick ‘Custom’ to enable the LED protocols customisation through voltage timing
adjustments on each port setting. By referring to the datasheet of your chosen pixel protocol, you can
configure the voltage timing to meet specific requirements and specifications.
Note
APA102 and 9PDOT are not compatible with Custom Timing due to protocol data and timing structure.
For creating a custom LED protocol, detailed instructions can be found in the ‘Custom Protocol Creation
Guide' document available on the ENTTEC website. Certain criteria apply, the eligibility requirements are
outlined in the guide.
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.
Input Protocol: Choose between Art-Net, sACN, ESP and KiNet as the input eDMX protocol.
Universes: Max 16U (8U per port). Overdrive mode activated automatically when configured to output more
than 4U per port.
It allows the option of using the same universes for both outputs, such as universes 1, 2, 3, and 4.
Alternatively, each output can be configured to use its own set of universes. For example, output 1 can use
universes 100, 101, 102, and 103, while output 2 uses universes 1, 2, 3, and 4.
Please note that only the first universe needs to be specified, as the remaining universes (2nd, 3rd … up to
8th) are automatically assigned subsequent universes based on the first one.
Example: If the first universe is assigned 9, the 2nd, 3rd and 4th universe 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 of
0 to 32767.
sACN: Each output can be assigned a universe number in the range of 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: Each output 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.
Note
In Overdrive mode, take note of Max FPS with each additional universe output, up to 8U max. ENTTEC
recommend performance trial before implementation.
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 strips 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 1,360 (RGB) or 1024
(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 the first
universe and GB channels in the second universe for an RGB LED.
For ease of pixel mapping, ENTTEC recommends 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 the 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.

I’m unable to connect to the OCTO MK2 web interface.
Ensure that the OCTO MK2 and your computer are on the same subnet.
To troubleshoot:
1. Connect the OCTO MK2 directly to your computer using a Cat5 cable and power it on.
2. Give your computer a Static IP address (e.g.: 192.168.0.20).
3. Change computer Netmask to (255.255.255.0).
4. Open ENTTEC EMU software.
5. Once EMU finds the OCTO, you will be able to open the device webpage and configure it.
Factory Reset the device using the reset button if the above steps do not resolve the issue.
The OCTO MK2’s factory default resets the OCTO MK2 to static IP address 192.168.0.10 and Netmask
255.255.255.0 with DHCP enabled.
When the OCTO MK2 has DHCP enabled but the DHCP server is unavailable (e.g. the device is connected to
a computer without a DHCP server), the IP address will fall back to 192.168.0.10 with netmask 255.255.255.0.
What if my LED strip protocol is not on the drop-down list? How to add a new LED
strip protocol to OCTO MK2?
The OCTO MK2 allows the user to choose a pixel output protocol even if it is not found in the drop-down
list.

Servicing, Inspection & Maintenance
The device has no user serviceable parts. If your installation has become damaged, the device should
be replaced.
Power down the device and ensure a method is in place to stop the system from becoming energized
during servicing, inspection & maintenance.
Key areas to examine during inspection:
Ensure all connectors are mated securely and show no sign of damage or corrosion.
Ensure all cabling has not obtained physical damage or been crushed.
Check for dust or dirt build up on the device and schedule cleaning if necessary.
Dirt or dust build-up can limit the ability of a device to dissipate heat and can lead to damage.
The replacement device should be installed in accordance with all steps within the installation guide.
To order replacement devices or accessories contact your reseller or message ENTTEC directly.
Cleaning
Dust and dirt buildup can limit the ability of the device to dissipate heat resulting in damage. The device
must be cleaned in a schedule fit for the environment it is installed within to ensure maximum product
longevity.
Cleaning schedules will vary greatly depending on the operating environment. Generally, the more extreme
the environment, the shorter the interval between cleanings.
Before cleaning, power down your system and ensure a method is in place to stop the system from
becoming energized until cleaning is complete.
Do not use abrasive, corrosive, or solvent-based cleaning products on a device.
Do not spray devices or accessories. The device is an IP20 product.
To clean an ENTTEC device, use low-pressure compressed air to remove dust, dirt and loose particles. If
deemed necessary, wipe the device with a damp microfiber cloth.
A selection of environmental factors that may increase the need for frequent cleaning include:
Use of stage fog, smoke or atmospheric devices.
High airflow rates (i.e., in close proximity to air conditioning vents).
High pollution levels or cigarette smoke.
Airborne dust (from building work, the natural environment or pyrotechnic effects).
If any of these factors are present, inspect all elements of the system soon after installation to see whether
cleaning is necessary, then check again at frequent intervals. This procedure will allow you to determine a
reliable cleaning schedule for your installation.
