Configuration of the IS-SPX Player Acting as Master
Identify the “master” IS-SPX Player that will serve as the NTP server, and configure it as follows through the Browser-
Based Configuration Pages:
1. In the Date/Time page, choose NTP Server and write the IP address of as many slave IS-SPX Players with static IP
addresses as possible in the server textboxes (Server 1, Server 2, etc.) (FIG.68).
2. Check the corresponding box(es) in the right column, under the title “Monitor only”. The check box must be
checked: if it is not, you will create a reference loop, and your system will not work correctly.
3. Select “0 s” in the menu list corresponding to the option Pause device at startup to wait for NTP servers by.
4. Click the Apply button.
With such a configuration, you will be able to switch on all your IS-SPX Players at the same time and have them
automatically synchronized between themselves.
Master/Server Architecture Examples
As the number of IS-SPX Players in your network grows up, several master/slave configurations become possible
(FIG. 70). The red arrows indicate the server address(es) entered in the master IS-SPX Player configuration (Monitor
only). The black arrows refer to the values entered for the slave IS-SPX Player(s).

Multiple levels of NTP hierarchies are strongly discouraged. For large installations, it
is more appropriate to invest in a NTP server.
