Chapter 10 – Presentation Properties

presentation start and republish the presentation. To set a single variable to its new default value, use the Reset

Variable command after republishing.

• Access: Select Shared to make the User Variable accessible to other presentations scheduled on the player. If

two presentations use a variable with the same name, the value of the variable with the Shared attribute will be

used for the variable with the Private attribute.

• Type: There are three types of User Variable.

o Local: Local variables can be changed with the Set Variable/Reset Variable commands or via the Local

Web Server. They can also be set with properly formatted serial and UDP commands.

o Networked: Networked variables are set and modified using Data Feeds (RSS, Live Data, or Dynamic

Playlists). To create a networked User Variable, you must first specify the Data Feed it will be linked to.

Select the desired Data Feed from the dropdown list and click Validate to ensure the link is operational and

has correct formatting for an RSS feed.

Note: Every RSS entry has a <title> tag and a <description> tag: use the <title> tag to designate the

name of the User Variable being modified; use the <description> tag to change the value of the User

Variable.

o System: System variables are not determined by the user, but by independent system parameters, such as

firmware/autorun version number, IP address, RF channel count, and various types of EDID (extended

display identification data) information received from the display over HDMI.

Note: Displays will often lack a complete set of EDID parameters. Make sure to test the EDID values of a

certain model before using them in a presentation.

To delete a User Variable, click the X beside the appropriate variable. You can also use the Delete Unused User

Variables button to delete all user variables that are not currently in use by Live Text states, commands, events,

conditional targets, etc.

Serial-send string (EOL), Serial-send string (no EOL), Serial-send byte, Serial-send bytes (comma separated),
