SRG-2200 User Guide (v6.0) DashBoard Menus • 53
This is the Primary/Backup SRG Tab
This tab appears if the SRG-2200 is set as the Primary unit in a Changeover pair. It informs the user that the
SRG-2200 is the Primary unit of a Changeover pair, and consequently, polling (of the remote device) is disabled.
When the SRG-2200 is set as the Backup unit in a Changeover pair, this menu line appears as one of the following:
•
“-Completed Polls = nnn”
— Where the field “nnn” will increment in conjunction with the number of
successful polls of the Primary unit.
•
“-Completed Polls = nnn”
— Where the field “= nnn” is blank if the previous line regarding the Polling
Interval is set for “Never”.
When the SRG-2200 is set as a Backup, this tab allows the user to define the Primary SRG-2200 IP Address and
Subnet Mask, set the number of seconds between pools of the primary SRG-2200, and shows the number of
completed polls of the Primary SRG-2200. It also shows the current Poll Status.
NTP/PTP Tab
Access to the NTP menu is only possible if the NTP option is enabled.
This menu line allows the user to control whether the SRG-2200 is configured to be an NTP Client or whether the
NTP System is off.
•
Find Server on — This menu line allows the user to define the IP address of a re mote web-based NTP Server
from which the SRG-2200 will periodically request time information. The address can be changed to one
preferred by the user. The options in the sub-fields are: 000 through 255. The value of 000 is the default “no
action” setting.
• Poll Server — This menu line allows the user to set the interval (in seconds) at which the SRG-2200 requests
NTP time information from the specified time server. One initial power-up, the SRG-2200 will poll the NTP
Server every 10 seconds until a reply is received, and then drop back to the user-selected value as programmed in
this menu sub-field.
• Poll Status — This menu line reports the current poll status of the designated NTP Server address. Initially, the
sub field will report that the SRG-2200 is currently waiting for replies from the designated NTP Server:
Poll
Status = Acquiring NTP
.
When replies from the designated NTP Server produce consistently accurate time stamps, the sub-field will change
to:
Poll Status = tLocked to NTP
.
During NTP acquisition, the following menu line appears below the Poll Status line:
Unlocked Poll every 010
secs
.
This menu line reports the polling interval when the NTP Server is being actively polled during initial acquisition.
The interval of 10 seconds should ensure that at least one reply will be found very quickly, After a reply has been
received, the polling interval drops back to the user setting made in the menu entry
Poll Server every 240
secs
above, and the following menu line appears.
The menu line
NTP time Uncertainty = nnnnms
reports the average variation in successive NTP replies.
