The root menu is shown when the receiver has completed initialization after power-up. With the four arrow
buttons and the buttons "OK", "ESC", "F1" and "F2" the navigation and setting of parameters can be ma-naged.
Main menu can be reached by pressing "ESC" some times. The main menu reflect some of the main param-
eters of the time server. First line shows the status of the Reference Clock, the NTP offset and the date and time.
In case of using a GNSS receiver (GPS, GNS, GNM) the text "GNS: NORMAL MODE" might be replaced
by "COLD BOOT", "WARM BOOT" or "UPDATE ALMANAC". If the antenna is disconnected or not working
properly, the text "ANTENNA FAULTY" is displayed instead.
Current time and date of the timeserver with the name of the time zone (NTP uses UTC time zone) will
be monitored in the bottom line. If the "IGNORE LOCK" option is enabled an "*" will be shown behind the time.
The multicolor LEDs will reflect the current state of the device:
„Ref. Time“
green: the reference clock (e.g. integrated GPS) produce valid time.
red: the reference clock produce no valid time (e.g. not synchronized)
„Time Service“
green: NTP has been synchronized to reference clock.
red: NTP is not synchronous to reference clock or sync to „local clock“
„Network“
green: all watched network ports has been “link up“ detected
red: at least one of the watched network ports (look at „Setup Device
Parameter / Check Network Linkup“) is not connected
„Alarm“
off: no error at moment
red: general error – more information will be shown on display.
