4.4.5.5 Time to live (TTL)
Why used
The TTL (Time to live) is a countdown time-out used to prevent the use of metadata information through
loss of communication.
The server or touch panel will continuously ask for the metadata status. As long as the ’time to live’ counter
has not been expired and the metadata status command is executed, this TTL value will be reset to its
original value set in the TTL interface.
If the TTL value reaches ’0’, the system will enable the metadata function.
How to set up
1. Tip into the TTL input field and select the current value. Change that value by entering the new value
with the digit keys on the keyboard (the value must be in seconds)
Or,
click on the up down of the spin box next to the TTL input field to change the value to the desired one.
