CHAPTER 1 MMB Web-UI (Web User Interface) Operations
Item
NTP Sets whether to enable or disable the NTP function.
With [Enable] selected, the MMB synchronizes with the time of the NTP server specified
below in [NTP1] to [NTP3].
The default is Disable.
NTP Time Correction Sets an NTP time correction mode.
Mode (This item is valid only if [NTP] is [Enable]. If it is set to [Disable], the item is grayed
out.)
The default is Step.
NTP 1 Sets the IPv4 or IPv6 IP address of the Primary NTP server.
(This item is valid only if [NTP] is [Enable]. If it is set to [Disable], the item is grayed
out.)
NTP 2 Sets the IPv4 or IPv6 IP address of the Secondary NTP server.
(This item is valid only if [NTP] is [Enable]. If it is set to [Disable], the item is grayed
out.)
NTP 3 Sets the IPv4 or IPv6 IP address of the Third NTP server.
(This item is valid only if [NTP] is [Enable]. If it is set to [Disable], the item is grayed
out.)
Current Sync Status Displays the synchronous status with the current NTP server.
- Enable
- Disable
- [Step]:
If the time difference with the NTP server is less than 128 milliseconds, the MMB
uses Slew mode (0.0005 seconds per second) to correct the time. The MMB corrects
the time as soon as the difference reaches 128 milliseconds.
If the time difference is outside a range of -1000 to +1000 seconds (16 minutes and
40 seconds), the NTP function stops.
- [Slew]:
The following action is taken depending on the time difference with the NTP server:
- If the difference is within a range of -600 to +600 seconds (10 minutes), the
NTP executes Slew adjustment, which corrects the time at a rate of up to
0.0005 seconds per second without reversal.
- If the difference is outside a range of -600 to +600 seconds (10 minutes) and
within a range of -1000 to +1000 seconds (16 minutes and 40 seconds), the
NTP executes Step adjustment. (In this case, the clock may be reversed.)
- If the difference is outside a range of -1000 to +1000 seconds (16 minutes
and 40 seconds), the NTP function stops.
- When synchronized: Displays the latest synchronous time together with the IP
address as follows:
xxx.xxx.xxx.xxx yyyy-mm-dd -dd:mm:ss
- When not synchronized: Displays "No Sync."
