•
ENABLE SNTP – If this box is checked, SNTP is enabled and the fields illustrated in Figure 4-15
are enabled for configuration.
•
SNTP Address – The SNTP host address is entered in this field. The field is available for
configuration if the ENABLE SNTP box is checked and the TPU 2000R hardware is selected.
•
SNTP Request - Two Radio Buttons are available for selection of SNTP update type. The
selections are:
o
o
•
SNTP TIMEOUT – This value is defined in milliseconds in which the synchronized time packet
must be received by the host server. If the time is not received in this time period, the TPU
internal clock is not synchronized.
•
UTC OFFSET HOURS: This value is enters in hours (format +/-XX.X) and is used to offset the
received UTC time so that local time can be displayed
If the TPU only supports serial time synchronization via IRIG B, then only the selections listed in Table 4-5 will be
available for configuration.
TIME SYNCHRONIZATION
MEHTOD
NONE
IRIG B
Simple Network Time Protocol
IRIG B
TABLE 4-5 : TIME SYNCHRONIZATION OPTIONS AND CONFIGURATION VALUES
Example: The following (IRIGB mmm) time is received from the TPU2000R:
82C6F096, where hour contains 82, minute contains C6 etc.
LISTEN – The TPU 2000R listens to the host and receives the time synchronization as
the host sends it.
PERIOD: Seconds- The TPU 2000R requests Time Synchronization from the SNTP
Host at specific time intervals. The time interval is specified in seconds.

ENABLE –cc
Or
ENABLE- mmm
ENABLE –cc
Or
ENABLE- mmm
Enable mmm for MMI
and COM.
This would represent the following time in hours minutes seconds milliseconds in
milliseconds from midnight:
