Green LED

Identifies the broadcasting status of the Transmitter.

  • Steady Green LED: Transmitter is broadcasting time.

  • Flashing Green LED: Transmitter is not broadcasting because of a user scheduled event, such as a Transmitter off request.

  • Green LED Off: Transmitter did not get an initial time and is not broadcasting, or a software/hardware error is preventing full transmission output.

Red LED (Error state)

Time source communication status

The status of a Transmitter's time source is indicated by its communication indicator, located on its front display.

  • GPS time source: when the connection symbol.png symbol is displayed the GPS Receiver is connected to the Transmitter and there is proper communication between the GPS Receiver and Transmitter. When the Transmitter is receiving valid time data from the GPS Receiver the three parentheses symbol Three_Parenth.png will sequence in a motion pattern.

  • NTP time source: when configured to receive time from an NTP time source, a S.png symbol is displayed.

  • Repeater (Satellite) Transmitter: when configured to receive time from another Transmitter, a R.png symbol is displayed.

Note

When the time source is NTP R.png or a Repeater (Satellite) Transmitter S.png, you will not see the three parentheses symbol Three_Parenth.png constantly. Time reception occurs at defined intervals depending on a number of different factors. If the Three_Parenth.png marks are not coming in continually, it's not a cause for alarm.

For a GPS time source, if the Three_Parenth.png marks are not appearing, the GPS Receiver is not receiving a signal from the satellites.

Time information

Time Zone

Only U.S. Time Zone information is displayed on the Transmitter display, however the Time Zone can be verified by checking to see that the correct hour is displayed once the Transmitter has received valid data from its time source.

The U.S. time zones displayed are: Eastern (E), Central (C), Mountain (M) or Pacific (P). The Transmitter can be set for all 24 time zones around the world.

12 or 24 hours

The 12/24-hour option only affects the Transmitter display. If AM or PM is displayed, then the 12-hour option is selected on the back. If neither AM nor PM is displayed, then the 24-hour option is selected.

US: Daylight Saving Time (DST)

The letters “DT” (Daylight Saving Time) or “ST” (Standard Time) is displayed when adjustment for Daylight Saving Time is active. The Transmitter is set to automatically make adjustments for DST. If neither “DT” nor “ST” are displayed, then DST does not apply and the DST/ST switch is in the UP position.

The adjustment to Daylight Saving Time and back to Standard Time takes effect at 2:00 AM on the day of change.
