Clock Management
NOTE: The Current Time is the date and time when the page was served.
The Current Time is used by all devices to time stamp system events and alarms. The clock
setting on all VNM 250 devices is factory set to UTC time and it is not necessary to make
any changes to the setting for the system to operate. The clock setting may be changed to
set the controller to local time, if required.
New Time is the updated date and time. It can only be modified by the admin user
and should be input in an identical format to the Current Time: year-month-date
hours-minutes-seconds .
z The year should include the century, eg: 2005.
z
The month is a number from 1 to 12
z
The date is a number from 1 to 31
z
Hours is a 24 hours clock number from 0 to 23
z
Minutes and seconds are numbers from 0 to 59
The time is updated by pressing Change Time .
Controller Licensing Management
The Controller licensing is used to enable the use of VNS 104 and VNM Software decoders
on a system. The Controller license contains two elements, an option and a checksum. New
licenses may be obtained from your Extron dealer when they are required. Talk to the Extron
S3 Technical Support (for contact information see the last page of this user guide).
Click on the
Change Licence button to open the License tab.
Alarms tab
From the Device List tab, click the Alarms tab:
Figure 22. Alarms Tab
The Alarms screen is used to monitor the active alarms on the system and to modify the
severity and reporting attributes of alarms on a device by device basis.
Alarms are descriptions of problem events with the system. They are raised and cleared
by hardware and typically have a 5 second hysteresis — once an alarm is raised, it stays
on for 5 seconds even though the error event has cleared. This prevents noisy conditions
saturating the alarm log buffer.
