2 Raspberry PI's (2 independent Monitors)

via network cross cable

The Cheapest way to use network multicasting is to use two systems connected via cross cable. This means there is no router needed.
In this example 2 raspberry PI's are used. Which is plug and play when latest image files are used. (Version 2.6.1.0 or newer).
Comparable solution is also possible making use of PC's.

 

Hardware

In this example

  • 2 Raspberry PI's are used.
  • Connected with a network cable. Formally it should be a cross-network cable. Both Raspberry PI's can also use a normal network cable. (There is no need to configure IP addresses. After connecting the cable the main system can sent the timing data to the follow system)
  • Both systems have a monitor connected via HDMI connector.
  • A keyboard/mouse is needed. Initially to setup the system. And later to control the system during archery matches. For controlling only one system needs a keyboard/mouse. In this example is chosen to use the right-side system as controlling (Main) system. The left-side system follows the other system (it is the client system).

    Off course it is also possible to setup the system such that left system is controlling and right system is following.

 

Configuring main system:

First select the main system. In this example the right-side system. This is the system used to control the timer.

 

The main system needs to send the timing signals over the network. So you need to enable the Checkbox "Broadcast time stamps over LAN network".

  • Go to the settings menu by pressing:
  • Select the network settings Tab.
  • Enable checkbox "Broadcast time stamps over LAN network"
  • Press "Save as startup settings" to ensure the checkbox is enabled next time you start up the program.

  • Close the settings menu by pressing:

 

Next step is to ensure this system is configured as right-side system. Since this is a specific setting needed for alternating, we need to configure this in alternating mode. After this we go back to "indoor/outdoor" to ensure this is the standard way to start up the system. Finally we store this as startup settings.

  • Go to the Timing and sequence menu by pressing:
  • Select "Alternating Finals" on the top side of the menu.
  • In the "Show" field select "right screen" to ensure this is the right side screen. (in case the left screen is used as main screen select left screen)

 

  • Select "Indoor Outdoor" on the top side of the menu. to ensure the system starts up in this mode.

  • Go to the settings menu again by pressing:

 

  • Press "Save as startup settings" to ensure the system starts up in this way at power up.

  • Close the settings menu by pressing:

 

 

Configuring "Follow" (Client) system:

Next configure the "Follow" (Client) system. In our example it is the left-side system.

 

 

  • Go to the Timing and sequence menu by pressing:
  • Select "Follow" on the top side of the menu.

 

 

  • Select "Left Side" at startup. This ensures the follow system starts up in follow mode and configured as left-side system. (In case you use the main system at left side and follow system at right side, you need to press "right side" at start up.)
  • Close the Timing menu by pressing:
