Management
The entire control of the Sync Source (here Module 8024GPS) is done by Module
8029HEPTA. All data of the Sync Source, indicated via WebGUI, are demanded
cyclically by Module 8029HEPTA from the Sync Source (here Module 8024GPS) or if
necessary. These data are then prepared for the display in WebGUI. After activation
settings for the Sync Source are transferred to the Sync Source immediately.
•
High Precision Time
The Sync Source provides a high-precision time information and the according
synchronization status to Module 8029HEPTA. This time and status information is
used for synchronization of the NTP service and if applicable other signal generations
running on 8029HEPTA.
3.2
Function 8029HEPTA (WebGUI: Device)
The Module 8029HEPTA is the "heart" of the Time Server 8029HEPTA/GPS. A complete
LINUX operating system is running on this Module providing all functions such as NTP,
WebGUI etc. The Module also controls the connected Sync Source (here Module 8024GPS).
Using the high-precise time information of Module 8024GPS the NTP service running on
Module 8029HEPTA is also adjusted with high-precision. Thus the Module 8029HEPTA is a
very precise
NTP STRATUM 1 - Time Server
.
3.3
Function 8024GPS (WebGUI: Sync Source)
The Module 8024GPS is in principle an independent Module with GPS receiver and its own
µProcessor. In synchronous status it provides a high-precise time information to the Module
8029HEPTA. The control of Module 8024GPS in this system is completely done via Module
8029HEPTA. Parameters required by Module 8024GPS or provided are entered into WebGUI
of Module 8029HEPTA or rather be output.
The Module 8024GPS has an own failsafe memory in which all required data for operation
after generation via WebGUI are stored.
As the data of the Sync Source for the WebGUI indication need to be received by the Module
8029HEPTA at first, it is
no real-time indication
in
WebGUI
.

LCD-Display with Pushbutton
System settings cannot be changed via the pushbutton nor the display. The display allows the
readout of important system and operation parameters directly at the device, even without
WebGUI access.
The data indicated in the display are applicable to updating-cycles such as the WebGUI. An
on-going process is indicated via the display.
