3.7 FRONT PANEL INTERFACE
3.7.1 The NTS-100 front panel is the primary user interface. Input is via three front panel
push-buttons and a 16-key keypad. Output is via the two-line 32-character alphanumeric
LCD. The alphanumeric display shows status and various function displays.
3.8 ALPHANUMERIC DISPLAY
3.8.1 The alphanumeric display is used both to display current clock status and as a means of
communicating information accessible through the NTS-100 list of keypad functions.
3.8.2 When not being used for keypad function operation, the alphanumeric display can be set
to display (in real time) the current clock mode or current time with calendar day and
year.
3.9 TIME PUSH-BUTTON
3.9.1 Pressing the TIME push-button places the equivalent time-of-year and the date on the
alphanumeric display. The format of the date is day-of-week, month, day-of-month, year.
3.10 STATUS PUSH-BUTTON
3.10.1 The Status Pushbutton displays the status of the NTS-100. The display will indicate that
the unit is either locked or unlocked to its synchronization input source. See Section 5 of
this manual for a detailed description of the status display for the synchronization input
option in your unit.
3.10.2 Additionally, PRESSING THE STATUS BUTTON WILL ABORT ANY KEYPAD
FUNCTION CURRENTLY IN PROGRESS. If an incorrect function was entered, or if the
alphanumeric display shows something unexpected, pressing the status pushbutton will
abort the function with no action taken by the function.
3.11 POSITION PUSH-BUTTON
3.11.1 Pressing the POSITION button will have no effect on the operation of an IRIG, ACTS, or
1PPS synchronized NTS-100.
3.12 KEYPAD OPERATION
3.12.1 The 16-key panel-mounted keypad consists of numeric keys "0" through "9", arrow keys
"up","down","right", and "left", a clear key "CLR" and the function/enter key
"FUNC/ENTR". Refer to "SELECTING FUNCTIONS AND ENTERING DATA" in this
section before attempting function entries. The following rules are for keypad function
entry:
• STATUS, or TIME should be on the alphanumeric display before starting a function.
If not, press the "STATUS" button.
•
It takes several seconds for some functions to appear. If nothing happens after
several seconds, press "STATUS", then try again.
•
When pressing keypad buttons, hold the button for 1/4 second to reduce contact
bounce and insure the key is recognized. Short "pokes" may result in bad entries.
