5.2.1.6 SNTP
Table 5–7: SNTP PROTOCOL SETTINGS
The G650 supports the Simple Network Time Protocol specified in RFC-2030. With SNTP, the G650 can obtain the clock
time over an Ethernet network. The G650 acts as an SNTP client to receive time values from an SNTP/NTP server, usually
a dedicated product using a GPS receiver to provide an accurate time. Three different modes of SNTP operation are
supported. These modes are unicast, broadcast and anycast.
If SNTP functionality is enabled at the same time as an IRIG-B source is connected to the G650, the IRIG-B signal provides
the time value to the G650 clock for as long as a valid signal is present. If the IRIG-B signal is removed, the time obtained
from the SNTP server is used.
To use SNTP in unicast mode,
Server IP Oct1...4
must be set to the SNTP/NTP server IP address. Once this address is
set and the
Function
setting is “UNICAST”, the G650 attempts to obtain time values from the SNTP/NTP server. Since
many time values are obtained and averaged, it generally takes forty seconds until the G650 clock is synchronized with the
SNTP/NTP server. It may take up to one minute for the G650 to signal an SNTP FAIL state if the server is off-line.
To use SNTP in broadcast mode, set the
Function
setting to “BROADCAST”. The G650 then listens to SNTP messages
sent to the “all ones” broadcast address for the subnet. The G650 waits up to eighteen minutes (>1024 seconds) without
receiving an SNTP broadcast message before signalling an SNTP FAIL state.
