synchronization between the units. Select this option to enable NTP and use its own
clock as a time source. You need to set up the time clock with Set Server Time/Timezone
option. You need to set the server clock using the Set Server Time / Timezone screen.
You can do this now, then return to the Configure Server window.

Select this option to enable NTP and be synchronized with an external time source on

21. If you did not select Use these Network Time Servers in the previous step, click Continue
and go to the next step.
If you selected Use these Network Time Servers in the previous step, complete the
following fields:
Specify up to three network time servers by IP address or DNS name in the order in which
you want the S8300 Media Server to check them. You should always specify at least two.
- Primary — Enter an IP address or DNS name.
If a trusted key is required, enter a valid key number in the Trusted Key field.
- Secondary — Enter an IP address or DNS name.
If a trusted key is required, enter a valid key number in the Trusted Key field.
- Tertiary — Enter an IP address or DNS name.
If a trusted key is required, enter a valid key number in the Trusted Key field.
- Multicast Client Support — Select Yes if the NTS routinely broadcasts its timing
messages to multiple clients.
Select No if the S8300 Media Server is to poll (directly request the time from) the NTS.
- Additional trusted keys (optional) — If you want to encrypt the messages between an
NTS and the S8300 Media Server, list the valid key numbers, up to 3, provided by your
LAN administrator on the pre-installation worksheet.
Trusted keys function like a checksum to make sure the time packets are valid. Use a
blank space as a delimiter if there is more than one key (for example, 2 3 6 to specify
valid keys 2, 3, and 6). These numbers are associated with encryption codes in a "keys"
file.
- Request key — Enter a key to send a remote query request.
Only 1 key is allowed in this field.
- Control key — Enter a key to query and request changes to an NTS.
Only 1 key is allowed in this field.
