Introduction

The MADRIX Backup System is a type of communication protocol between two or more MADRIX computers in order to set up a reliable backup solution.

A backup solution should get involved as soon as the main control solution fails.
Regarding the MADRIX Backup System, so-called keep-alive messages are sent by one MADRIX computer to other computers to check if the connection between the computers is working properly.
If the Master fails, i.e. if the Master does not send keep-alive-messages in a certain time interval [in seconds], the Slave is automatically activated and sends the output data to the LEDs.
Similarly, the Slave is sending keep-alive messages.

 

 

Important Note

Make sure that all computers are equipped with a MADRIX software license [i.e. a MADRIX KEY] and the same MADRIX software version!

 

 

Overview

Go to Preferences > Backup System...
A new window will open.

Backup System Window

 

Enable - Activates the backup system.
Keep-Alive Time (s) - Defines the time range between keep-alive messages [in seconds]. Valid values range from 0.1 to 25.6.
Drop-Down List - Allows you to choose the correct network card if your computer or laptop is equipped with more than one network card.
Validate MADRIX KEY - MADRIX automatically monitors if the MADRIX KEY is is plugged into the Master.
Receive Sync Commands From Master - Activates that the computer receives synchronization signals from the Master. [This is mainly useful for the Cue List. It is a useful feature to play back Cue Lists synchronously.]
Change Master - Allows you to select another computer in the list of found network computer and set this computer as the Master. You are not allowed to select your local computer as Master. You will have to choose a remote computer.
- Allows you to manually remove outdated list entries.

 

 

How To Connect Master And Slave

Master and Slave Illustration

 

You can utilize your network card with an Ethernet port to connect two ore more computers using a network switch.
Set up the IP addresses from the computers like in the picture above.
Both computers have to be in the same network address area [e.g., 192.168.0.1 to 192.168.0.254].

 

 

Example 1: How To Use The Backup System And Art-Net

Art-Net Backup System Illustration

 

It is recommended to always use two separate networks with two network cards if you want to sync Master and Slave and use Art-Net at the same time.
Minimum requirements for this set-up are:
- 2 computers
- 2 Ethernet switches
- 1 or more Art-Net devices
- Ethernet cables
- DMX cables.
Apart from that, both computers need to have two network cards installed. The set-up for the first network is 192.168.0.X and the second is 2.0.0.X
- The former will be used as the backup system, the latter is transferring Art-Net data.

In addition, you may use a variation of the example above.
Depending on your installation, it can be possible to do the setup without the second network. It is a smaller budget alternative and in this case only the Art-Net network will be used.
At the same time this means that traffic from both Art-Net and the backup system will be transferred over this single network. In larger installations this might cause network problems due to high data traffic!
Connecting this backup system to the internet is not recommended because problems with the internet connection are likely to occur [such as connection errors, dropouts, etc.]. WiFi-nodes are also not recommended. The Art-Net data will simply interfere with the internet data in the 2.0.0.X network.
If your Art-Net interfaces support the 10.0.0.X network, you may establish an internet connection since the Art-Net data may be blocked by your router and does not interfere with the internet connection.
 

Such an installation is at your own risk.

 

 

Example 3: How To Use The Backup System And USB DMX512 Interfaces

Backup System with USB DMX512 Interfaces

 

If you are going to use an USB DMX512 interface, you can work with one network card to sync Master and Slave.
Minimum requirements for this set-up are:
- 2 computers
- 1 Ethernet switch
- 1 DMX merger
- 2 DMX512 devices
- Ethernet cables
- DMX cables
Apart from that, both computers need to have a network card installed. The set-up for this network is 192.168.0.X. Only this card/network will be used for the backup system.
