Local or Global Broadcasts
Choose whether broadcasts will be local or global from the 'BROADCAST TYPE' radio buttons. The setting
changes between using the global broadcast address or a local broadcast address. The global broadcast
address is 255.255.255.255, while the local broadcast address depends on the network settings. For example,
if the port's IP is 192.168.1.1 and the netmask is 255.255.255.0, then the local broadcast address will be
192.168.1.255.
By default, the broadcast type is set to 'GLOBAL'.
4.
Enter Broadcast Interval
Enter the broadcast interval into the 'BROADCAST POLLING INTERVAL' timeboxes. This setting determines
how frequently the port will send broadcast NTP messages into the network. The supported interval range is
0-24 hours, the default setting is 2 seconds.
5.
Save Settings
Click the 'SAVE' button to write the settings to the GridTime 3000.
A 'Saved!' notification will appear in the bottom right corner of the page indicating that the settings have
successfully been written to the GridTime 3000.
