Windows Network configuration for pixel LED controllers

Many of our clients still struggle with configuring network (sometimes called Ethernet/Internet) settings in Windows when using pixel LED controllers. This video provides all the essential details for proper Ethernet (Network) configuration in Windows.

What is Network? #

The easiest explanation of a network is a group of computers or controllers connected via Ethernet cables and Ethernet switches. It allows the computers to “talk” to each other and all the devices connected to the network.

Simple Ethernet Network

IP Address #

In a simple Ethernet network, every device or computer connected to the network has an IP address. An IP address is typically written as four numbers (ranging from 1 to 255) separated by periods, such as 192.168.1.22. These IP addresses enable devices to communicate with each other.

How to set the IP address of the computer? #

To set the IP address of a computer, follow these steps:

  1. Go to “Network & internet” in Windows Settings.
  2. Choose “Advanced network settings” and then “More network adapter options.”
  3. You’ll see a list of all the network adapters connected to your computer, typically including Ethernet and Wi-Fi adapters. The Ethernet is typically used for your wired connection.
  4. Double-click the Ethernet adapter to access its settings, including the current IP address.

In the Ethernet adapter settings, you can view the current IP address by clicking on “Details.” To change the settings, click on “Properties,” which will display the detailed settings of the adapter.

Ethernet Properties

There are several settings, but if you want to change the IP address, click Internet Protocol Version 4 (TCP/IPv4).

Default IPv4 Settings (DHCP)

By default, the IP address is set to be obtained automatically (via DHCP). However, you can click on Use the following IP address to manually set the desired IP address. For the LED Ethernet Controller 3, the recommended IP address range is 192.168.1.1 to 192.168.1.254.

How to set the IP address of the controller? #

Setting the IP address of the controller depends on the specific controller you are using. Some controllers provide DIP-switch settings, while others have a control display or web configuration options.

For our controllers, such as the LED Ethernet Controller 3, the IP address is set via web configuration. Web configuration is accessed through a web page stored inside the controller, which can be accessed from a computer using a standard web browser (like Chrome or Internet Explorer). To access the web configuration, you need to enter the LEC3 IP address in the address bar. The default IP address for new LEC3/SPI Matrix controllers is 192.168.1.147.

In the example provided, if you set the IP address of your computer to 192.168.1.22, you should be able to access all your LEC3 devices’ web configurations by typing 192.168.1.x in the address bar of your web browser. This applies when you connect the Ethernet cable directly from the computer to the LEC3 controller.

PING-it! #

To identify whether a device with a specific IP address is connected to the network, you can use the “ping” command.

Ping is a command-line tool used to check the connectivity to an IP address on a network.

To use this tool, go to the command line in Windows by clicking the Start menu and typing cmd. This will open the command-line window, where you can enter commands. 

Command Line in Windows

To ping a specific IP address, type ping 192.168.1.161. This will send test data to the IP address, and if there is a device or computer present at that IP address, you will receive a reply.

Correct Ping Reply

If there is no device or computer at the IP address you are pinging, you will typically receive an error message saying Destination host unreachable.

We’ve tried to provide a clear explanation of networks, IP addresses, and how to set them up on computers and controllers. You should now be able to set the IP address of your computer and LEC3/SPI Matrix device and prepare them to be used with LED Strip Studio software.
