Firmware Update
A H8 firmware update of the Sync Source (here Module 8024GPS) is completely con-
trolled by Module 8030HEPTA.
The update file for Module 8024GPS is loaded into Module 8030HEPTA via LAN
through the WebGUI. Then Module 8030HEPTA performs the update of the Sync
Source (here Module 8024GPS) independently.
•
Management
The entire control of the Sync Source (here Module 8024GPS) is done by Module
8030HEPTA. All data of the Sync Source, indicated via WebGUI, are demanded cy-
clically by Module 8030HEPTA from the Sync Source 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 syn-
chronization status to Module 8030HEPTA. This time and status information is used
for synchronization of the time sync services and if applicable other signal generations
running on 8030HEPTA.

Function 8030HEPTA (WebGUI: Device)
The Module 8030HEPTA is the "heart" of the Time Server 8030HEPTA/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 and all further
time sync services running on Module 8030HEPTA is also adjusted with high-precision. Thus
the Module 8030HEPTA 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
8030HEPTA. The control of Module 8024GPS in this system is completely done via Module
8030HEPTA. Parameters required by Module 8024GPS or provided are entered into WebGUI
of Module 8030HEPTA 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
8030HEPTA at first, it is
no real-time indication
in
WebGUI
.
3.4
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.
Update of the data in both the display and the WebGUI is subject to specific refreshing cycles.
The display indicates if the refreshing cycle is not completed yet.
