Network Time Protocol is an internet protocol used to synchronize computer clocks to the same time reference.
The unit can run as a server application and a client application. In addition, broadcast mode may be implemented as either a server or client. The NTP server always runs and the client and broadcast modes are enabled independently by assignment of addresses and setting of timers.
Click Edit to change the Network Time Protocol parameters. The fields are described in the table below.
Field / Section |
Description |
NTP IP Address 1 |
|
Mode Selection |
The are Not Assigned, Broadcast Server, Broadcast Client, and Client. |
IP Mask |
The IP Mask is displayed only if the Broadcast Server option is selected in Mode Selection. This is the IP mask of the time source. |
Interval |
The interval is displayed only if the Broadcast Server option is selected in Mode Selection. Interval defines the rate in seconds at which the time is broadcast by the server. |
IP Address |
The IP Address is displayed only if the Broadcast Client or Client option is selected in Mode Selection. This is the IP address to be used as broadcast client or client. |
Offset |
The Offset is displayed only if the Broadcast Client or Client option is selected in Mode Selection. This is the number of seconds used to adjust the local time. |
Delay |
The Delay is displayed only if the Broadcast Client or Client option is selected in Mode Selection. This is the calculated delay in the communication path. |
Dispersion |
The Dispersion is displayed only if the Broadcast Client or Client option is selected in Mode Selection. This value indicates the accuracy of the offset/delay settings. |
Interval (Sec) |
Sets the rate (in seconds) at which the time is to be broadcast by the server. |
NTP IP Address 2 and 3 |
|
Mode Selection |
The are Not Assigned, Broadcast Server, Broadcast Client, and Client. |
IP Address |
The IP address to be used as broadcast client or client. |
Offset |
The number of seconds used to adjust the local time. |
Delay |
The calculated delay in the communication path. |
Dispersion |
This value indicates the accuracy of the offset/delay settings. |
Interval (Sec) |
Sets the rate (in seconds) at which the time is to be broadcast by the server. |
Current System Mode |
Displays the current mode setting for the system. |
PREFER |
Indicates the preferred time-of-day source in the SSU-2000 from GPS or an NTP client. |
