Synchronizer Status view

Full information on the status of the Synchronizer module is given in the Synchronizer Status view. For a detailed description of the columns of its spreadsheet see the following table.

If data from a specific epoch of a station did not arrive in time (that is, within five seconds after the arrival time of the epoch received from the first receiver), the Synchronizer will send all of the data to the depending module without the missing station's observations.

Synchronized output: Informs you of the epoch time (date, and time in HH:MM:SS), for which the last set of collected data has been sent to the depending module. Behind the output time, the number of modules is shown, which have delivered observations in time.

Epoch delay: Delay of data for the current epoch. Typically, that is the delay of the last contributing station whose epoch arrives in time to be forwarded to depending modules.

Last hour delay: Average of the epoch delays of the last hour.

Average delay: Average of the epoch delay computed from all epochs.

Available columns in the Status view table:

Column	Description	More Information
Status icon	Visually describes the current status of the station.	Green: stations are synchronized. Yellow: a delay of more than two seconds of the station data to the arrival time of the epoch received from the first receiver. The synchronized data is passed on without this station's data. Red: no data received or no data received in time (that is, within two seconds) for more than one minute. The module does not anymore expect data from this station.
Source	Module type and configuration name
Station Name	Station name
Station ID	Station ID	By default: Hidden. Tip - Use the Choose Columns shortcut menu command to display or hide columns.
Station Code	Station code
Received Epochs	Summarized epochs received from this station.	Since Synchronizer module startup, or since GNSS Receiver module startup, whichever happened last.
Used Epochs	Summarized epochs from this station passed on to depending modules.	Used epochs may be less than received epochs, because of epochs arriving too late.
Too Late Epochs	Summarized epochs arriving too late	Epochs of this station are too late, if they arrive more than 2 seconds later than the arrival time of the epoch received from the first receiver.
Received	Date and Time of the last received epoch.	In DD.MM.YY HH:MM:SS, GPS time.
Max. Delay	Maximum value of all delays having occurred so far.	Value is displayed visually and in milliseconds.
Average Delay	Average of delay over all used epochs for this station.	Value is displayed visually and in milliseconds. See the summarized epochs in the Used Epochs column.
Last Hour Delay	Average of delay over all used epochs of the last 60 minutes for this station.	Value is displayed visually and in milliseconds.
Delay	Current delay relative to the first station sending that epoch.	The delay is displayed visually and in milliseconds.

Note - The update interval of the status messages depends on the bandwidth control setting you have selected when logging in to the Trimble 4D Control Server UI.
