PVIQ™ CONNECTIVITY SYSTEM USER MANUAL V 1.0
53
Secondary IP
This is a user-changeable field that allows the customer to enter the IP address of the
Secondary (back up) NTP server that they want the PViQ™ Connectivity System to get
the time from. If connection to this server fails, the system will attempt to get the time
from the Tertiary (next back up) NTP server.
Tertiary IP
This is a user-changeable field that allows the customer to enter the IP address of the
Tertiary (next back up) NTP server that they want the PViQ™ Connectivity System to
get the time from. If connection to this server fails, the system will attempt to get the
time from the Primary NTP server again.
NOTE: The PViQ™ Connectivity System will always attempt to get the time from the
Primary NTP server first (every time the system resynchronizes) and fails over to
Secondary NTP server, then fails over to the Tertiary NTP server.
Refresh Rate
This is a user-selectable pulldown menu that allows the customer to select the refresh
rate in minutes. The refresh rate is defaulted to 720 minutes (12 hours). The refresh rate
is the rate at which the system will synchronize its time to the NTP server. This refresh
rate may be set from 360 minutes (6 hours) to 7200 minutes (120 hours). Selecting a
higher number will allow the system time to drift more between NTP server
synchronization. Selecting 360 will minimize the drift in time on the PViQ™ Connectivity
System between NTP synchronizations.
Time Zone
This is a user-selectable pulldown menu that allows the customer to select the time
zone their PViQ™ Connectivity System is in. The time zone is defaulted to -6:00 hours
(Central Standard Time). NTP servers all set to UTC (Coordinated Universal Time). The
numbers in this selectable pulldown menu allow the user to set the local real time with
respect to the UTC time.
Date/Time
This section provides the date and local time of the PViQ™ Connectivity System.
Date
This is a read-only field that is automatically updated with the date that the PViQ™
Connectivity System is set to. The format of this field is year/month/day.
