Using an IS-SPX-1000 as an NTP server
Under certain circumstances, you may want to use an IS-SPX-1000 player as a time server for the other
devices in a network:
You don't have a local NTP server and want to use public servers. In this case, one IS-SPX-1000
will synchronize to the public servers and the other players will be synchronized to this device.
This will provide better accuracy between all the devices.
The IS-SPX-1000 does not have access to the network. In this case, one of the devices is used as
master whereas the others use its time as a reference. This will not prevent your installation from
time drifting, but will ensure that all the devices are synchronized.
You have two players that need to be synchronized. In this case, the two devices can be connected
by a cross-over cable and one IS-SPX-1000 configured to be the time reference for the other.
In all of these scenarios, you will have two types of devices: a master and one or more slaves. One IS-SPX-
1000 will play the role of NTP server (master), and the others will connect to it for getting the correct time
(slaves). Before adopting this solution, please note that this is less reliable than the standard one; in particular
it's important to know that the clock of the IS-SPX-1000s will drift apart from UTC time.
Configuration
Each device is ready to work as a NTP server, but a few parameters must be set to assure a smooth overall
operation, thus execute the following procedure:
1. Designate one and only one device player as the master. It should have a static IP address. The clock
should be properly calibrated before use. (For calibration information, please refer to the
Troubleshooting section on page 69.)
2. All of the other IS-SPX-1000 players are slaves. They should also have static IP addresses, but this is not
strictly required.
Configuration of the IS-SPX-1000 players acting as slaves:
1. Identify the “slave” IS-SPX-1000 and open its Browser-Based Configuration Pages.
2. In the Date/Time page, choose NTP Server and enter the IP address or URL of the “master” IS-SPX-1000
in the first textbox (Server 1) (FIG. 60).
3. Select 90 s in the menu list corresponding to the option Pause device at startup to wait for NTP servers
by.
4. Click the Apply button.
5. Repeat this procedure for all your slave devices, but not the “master” (FIG. 61).
