Setting the Multiviewer’s Time and Date
Setting the Multiviewer’s Time and Date
The multiviewer receives date and time information from the Densité CPU-ETH2 controller
upon startup. The date/time or NTP settings for this multiviewer cannot be configured in
XAdmin. Make sure the controller’s internal clock is correctly set. The clock settings will
persist for 10 days after a power loss. Should you need to change the time on a Densité
CPU-ETH2 controller, then make sure to restart all multiviewers located in the same housing
frame as the controller card.
Once you have set the Densité CPU-ETH2 controller’s IP address, you can access the Densité
CPU-ETH2 controller’s web interface through the network to set the frame’s parameters
such as the multiviewer’s time and date. You can obtain the Densité CPU-ETH2 controller’s
IP address through the:
• frame’s local control panel. See Setting a Densité CPU-ETH2 Controller’s IP Address , on
page 33.
• XAdmin web interface, found under System Configuration , Housing frame . See
Configuring a Multiviewer’s IP Settings with XAdmin , on page 74.
The multiviewer uses an internal clock to keep time. A network timeserver can optionally
be used to keep the multiviewer’s clock synchronized to a network time source using the
Network Time Protocol (NTP). Using NTP synchronization eliminates the long term drift that
affects the internal clock and ensures that all networked equipment operate with respect to
the same network time reference.
To set the time and date
1 With your PC, open a Web browser window and type the Densité CPU-ETH2 controller’s
IP address in the address bar.
The Densité CPU-ETH2 controller’s home page appears.
2 Click Time/Date or Date and Time under Setup in the left hand menu tree.
The time and date configuration parameters are shown.
3 Enable NTP Synchronization , then set the IP address of one of more time servers and set
how often the network time server is to update the internal clock ( NTP Refresh Rate ).
Otherwise disable NTP Synchronization and set the current time and date.
4 Click Apply .
