Extron electronics VNM EC 200, User Manual, Page: 34 / 242

Clock Synchronization Panel
This panel (see figure 18 ,
2
on the previous page) is used to determine the master clock
source for the controller.
NOTE: If there is only one VNM EC 200 in the system, it is not necessary to configure
clock synchronization.
All devices in a VN-Matrix system (controllers, encoders, decoders, and recorders) reference
a master system clock, sourced from the controller.
If the
Enable Clock Synchronization check box is selected (checked), the controller
that is logged in offsets its own time to match the system time of the first VNM EC 200 in
the
Sources list. If the first controller fails, the system time of the second controller in the
list is used as the reference, and so on.
If the
Enable Clock Synchronization check box is not selected (unchecked), the
controller that is logged in references its own clock for the system time (in the case of a
singleton system with one VNM EC 200) or the time of the controller acting as the primary
(in the case of a paired VNM EC 200 cluster).
NOTES:
• Only physical IP addresses of VNM EC 200s should be added to the Sources list.
Do not use service (cluster) IP addresses.
• The order of the controllers in the Sources list should be identical for each
VNM EC 200.
Adding controllers to the Sources list
NOTE:
Only IP addresses of valid controller devices can be added to this list.
1. To add a controller to the list, click the button (
1
) located below the Sources list
(see figure 18 ,
2
).

2. The Peer Controller Address dialog box opens.
3. Enter the desired IP address and click OK .
4. Repeat steps 1 through 3 for each controller in the VN-Matrix system.
5. When finished adding controllers, click Apply Changes located at the lower right
corner of the Web page (see figure 18 ,
5
).
