Configuring the SNTP/UTC Time Clock

To configure the SNTP/UTC clock
• Add an NTP server, if the one to which you want the CCU to synchronize has not
already been added. You may want to delete the default NTP servers, to force the
CCU to synchronize to the server you are adding.
• Set the SNTP client resynchronization period. The factory default setting is
3600seconds, and WaveRider recommends not changing this default setting.
• Set the SNTP client retry period. The factory default setting is 30seconds, and
WaveRider recommends not changing this default setting.
• Enable the SNTP client, to force the CCU to synchronize to an NTP server.
• Enable the SNTP relay, if you want the EUMs to be synchronized to the CCU.
