Connecting the device's web interface allows remote configuration of the device’s settings and is a strong indicator that the device is active on the network. The device's web interface can be accessed from any web browser within the same network by entering the device's IP address into the URL field of the web browser.

Networking Basics: Each Ethernet devices on a network requires an unique identifier (IP Address). There are two different methods to provide an Ethernet device with an IP address:
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 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.

Over the years there has been some slight differences between ENTTEC products. Remember that you will also need to set the computer to be within the same range as the device. Please use the table below to select your ENTTEC product:

Discovery Method A

Default settings (out of the box):

The device is 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 (see below).

Default static IP address:

If there is no DHCP server on the network, or DHCP is disabled and, the static IP address hasn't been changed then the device can be accessed via the default static IP address. Printed on the devices is the Serial Number of the device, from this we can convert the Hex values to Decimal values to identify the devices default static IP address. 

The first part of the IP address will be 10 followed by the last three bytes (pairs) of the Serial Number. For example a Serial Number of 0050C082356 will be converted as follows: 0050C(08)(23)(56)

Now finally we will need to change the IP address of the computer to enable us to access the web interface. We recommend that your computer is set to the following settings:

• IP Address: 10.0.0.100
• Subnet: 255.0.0.0

For assistance on this please see: Set the computer to be within the same range as the device.

Discovering the devices IP address (if DHCP or the Static Address has been changed):

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 one of the following a discovery methods:

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

Once the IP address has been discovered you will need to set the computer to be within the same range as the device.

Discovery Method B

Default settings (out of the box):

The device is 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 (see below).

Default static IP address:

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

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

As long as your device is still set to the default static IP address, then we recommend that your computer is set to the following settings:

• IP Address: 192.168.0.100
• Subnet: 255.255.255.0

For assistance on this please see: Set the computer to be within the same range as the device.

Discovery Method C

Default settings (out of the box):

The device is 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 (see below).

Default static IP address:

The default static IP address will be displayed on the LCD screen.

You will need to set the computer to be within the same range as the device to be able to access the web interface

Discovering the devices IP address (if DHCP or the Static Address has been changed):

The default static IP address will be displayed on the LCD screen.

You will need to set the computer to be within the same range as the device to be able to access the web interface

Set the computer to be within the same range as the device

Now you should know the IP address of your device, if you are unsure, please read this article from the top. 

With this IP address it is important to set the computers IP address to be within the same range to enable you to access the web interface. It is recommended that you match the IP address of the device whilst only changing the last of the four digits to enable your computer to have a unique IP address. 

Please see our Windows and macOS guides on how to bring your computer’s network settings in line with your device’s network settings.
