interruptions of the synchronization input, the NTS-100 will estimate the quality of the
time it is able to provide to clients and update the fields of the NTP packet appropriately.
In addition, the time quality character of the Serial I/O Function 08 string and the “worst
case time error” reported by Function 13 are also updated during such interruptions. The
NTS-100 will provide NTP server operation until the Function 13 “worst case time error”
has exceeded the value of the Root Dispersion field set in the NTP packet. See
Appendix A for details on this behavior.
3.5
GENERAL OPERATION
3.5.1
The two most-used functions (TIME, and STATUS) have been assigned to front-panel
pushbuttons. The POSITION pushbutton has no function on the NTS-100-IRIG,
NTS-100-ACTS or NTS-100-1PPS. All functions may be accessed via the front-panel
keypad and viewed on a front-panel alphanumeric display or accessed via the Serial I/O
interface and viewed on a monitor.
3.6
NTS-100 START-UP
3.6.1
At power up, the unit will present messages on the small front panel display to indicate
the version of software installed in the unit, and how to invoke the keypad help function.
The first message is the version of the system software. For example:
TRUETIME NTS
sys ver 014
3.6.2
After a few seconds, the display will show:
Press func, 0, 0
for help.
3.6.3
Then the display will show the version of the clock-specific software:
NTS V1.003
(Example)
182-7002v001
3.6.4
After a few seconds, the display will show the status display, which will remain until a
keypad function is invoked, or the "TIME" button is pressed.
3.6.5
It should be noted that the text of the version messages and status display will vary from
model to model and version to version.
