Connecting the device web interface allows remote configuration of the device’s settings and is a strong indicator that the device is active on the network.


Ethernet devices require an IP address. - This is the device’s unique identifier on the network. To connect to the device’s web interface, we need to enter the device's IP address into the URL field of a web browser on a computer on the same network (the same IP address range) as the device. Please see our Windows and macOS guides on how to bring your computer’s network settings in line with your device’s network settings.


Networking Basics

There are two different methods to provide an Ethernet device with an IP address.

  • DHCP: Dynamic Host Configuration Protocol (DHCP) automatically configures the IP address for devices on a network, ensuring that each device has a unique IP address. A DHCP network requires one DHCP server, which tracks which IP addresses are in use, and provides a unique IP address to devices connected to a DCHP server while the device is being powered on. An example of this is a home Wi-Fi router, which provides any devices connecting to the Wi-Fi with a unique IP address. 
  • Static IP: This allows you to assign a particular IP address to a device manually. By using a Static IP address, you do not need a DHCP server (usually a router) on the network. This is also ideal for long-term installations as this will ensure the device continues to receive commands from devices unicasting to it, whereas if you were using DHCP, there is a chance that the IP address could change after a power cycle.

Additionally, the Subnet Mask controls what devices can communicate with each other. The two most common numbers on a Subnet Mask are 0 and 255, representing the lowest and highest values within networking. As with the IP address, the Subnet Masks has four values separated by a decimal. The Subnet Masks value 255 means that the corresponding IP address value is blocked, whereas the Subnet Masks value 0 means the corresponding IP address value is open. For example:

  • If the device’s IP address is 192.168.0.10 with a subnet of 255.255.255.0, the device can only talk to devices with an IP address of 192.168.0.1 thru to 192.168.0.254, as the first three values of the devices IP address are blocked. 
  • If the device’s IP address is 10.0.0.60 with a subnet of 255.0.0.0, the device can talk to devices with an IP address of 10.0.0.1 thru to 10.254.254.254, as only the first value of the devices IP is blocked.


Devices without an in-built LCD Screen

As these devices do not have a screen, it is not automatically obvious what the device’s network settings are; to find the device’s IP address; we need to use a discovery method.


ENTTEC EMU software (Windows and macOS) will Discover ENTTEC devices on Network, display their IP addresses, and allow you to configure them. Alternative discovery methods include:

  • 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).

Default settings (out of the box):

These devices are set to DHCP by default. If the DHCP server is slow to respond, or your network does not have a DHCP server, the device will fall back to the default static IP address.

Default static IP address:

The default static IP address is calculated differently for different devices. Please follow the appropriate instructions for your device.

The following instructions apply to:
  • Ethergate Mk3 (70070)
  • ODE Mk2 (70405)
  • ODE POE Mk2 (70406)
  • Pixelator Mini (70066)
  • Pixelator Mini PX1-8D (71066)
  • Storm 8 (70055)
  • Pixel Octo (71520)
  • Pixel Triton (75020-12 / 75020-24)
  • Pixel Port (76302)

Computer Settings:

As long as your device is still set to the default static IP address (a custom one that has not been defined in the web interface in the past - if it has, view the non-default discovery section below), then we recommend that your computer is set to the following settings:

  • IP Address: 10.0.0.100
  • Subnet: 255.0.0.0

Method: Hex to Decimal 

These devices will be set to a DHCP IP address. Suppose the DHCP server is slow to respond, or your network does not have a DHCP server. In that case, the device will fall back to the default Static IP address, printed on the device’s packaging and can be calculated from the last three bytes (pairs) of the Serial Number, converting the Hex (bytes) into Decimal values. The IP address will read as 10.(byte1).(byte2).(byte3) For example, if your Serial Number is 0050C082356, the last three bytes (pairs) are 08, 23, and 56; when converting these Hex values to Decimal Values, the conversion defaults static IP: 10.8.17.38.

N/A 08 23 56
 10 8 17 38

The following instructions apply to:
  • Octo (71521)
  • DIN ETHERGATE (71030)

Computer Settings:

As long as your device is still set to the default static IP address (a custom one that has not been defined in the web interface in the past - if it has, view the non-default discovery section below), then we recommend that your computer is set to the following settings:

  • IP Address: 192.168.0.100
  • Subnet: 255.255.255.0

Method: 192.168.0.10

The device will fall back to the default Static IP address, 192.168.0.10.

Note: When configuring multiple DIN ETHERGATEs on a Static network, to avoid IP conflicts, ENTTEC recommends connecting one device at a time to the network and configuring an IP.

Non-default discovery

Unless the device is fresh out of the box, it will be set to DHCP enabled with the fall back to the default static IP address (above), then it can be challenging to identify the device’s IP settings when you first approach it.


There are four possible scenarios:


Default IP Address

Unique IP Address

DHCP Enabled

Scenario A (OUT OF THE BOX): Devices request an IP address from a DHCP network.

If the DHCP network provides no IP address, the device will switch to the default IP address (see above).

Scenario B: Devices requests an IP address from a DHCP network.

If the DHCP network provides no IP address, the device will fall back to the unique static IP address set previously.

DHCP Disabled

Scenario C: Devices will not request an IP address from a DHCP network.

Instead, the device will switch to the default IP address (see above).

Scenario D: Devices will not request an IP address from a DHCP network.

Instead of the DHCP network, the device will switch to the previously set static IP address (overriding the default IP address).

The three steps below will guide you through how to find your device efficiently:

Step 1: Connect the device to a DHCP network.

We recommended connecting to a DHCP network as the first step as this will detect any devices with Scenario A & B. 

Use the links to articles on setting up a DHCP network for Windows or macOS.

Step 2: Connect the device to a static network and try the device’s default IP address.

If you could not find the device using DHCP, it is likely to be disabled within the device. The next step would be to test Scenario C, as the default static IP address is a known variable.

Use the links to articles on setting up a static IP address on your Windows or macOS computer. Depending on your default static IP address discovery method (see above), we recommend that you set your computer to the following:

Default static IP address method (see above)

Computer’s IP Address

Computer’s Subnet Mask

Method: Hex to Decimal

10.0.0.100

255.0.0.0

Method: 192.168.0.10

192.168.0.100

255.0.0.0

Step 3: Connect the device to a static network and identify the unknown custom IP address.

If you could not find the device using the default IP address, it is likely to be Scenario D, where a custom IP address has been set within the device's settings. On this occasion, we strongly recommend using the same static IP address configuration as set in Scenario C with our free NMU (Node Management Utility) software for Windows and macOS (support up to Mac OSX 10.11), which will Discover all ENTTEC devices on the Local Area Network, displaying their IP addresses. Our NMU software can discover ENTTEC devices that are not on the same IP address range as your computer, enabling you to discover the custom IP address which has been set. Note: NMU will need restarting after every IP address change.

Devices with an in-built LCD Screen

The following instructions apply to:

  • S-Play (70092)
  • Datagate (70044) - RevC.
  • Pixelator (70060) - RevC.
  • Storm 24 (70050) - RevC.

As the device has an LCD screen, the device’s IP address can be determined by looking at the home page of the menu. This can be found by pressing the BACK button.


For information on changing the IP address using the LCD screen on your device, please visit the device-specific user manual on our website.


Default settings (out of the box):

These devices are set to DHCP by default.
