1 GPS - NTP Time Server 8029HEPTA/GPS
By GPS time synchronization and the worldwide used time protocol NTP (Network Time
Protocol) the Time Server 8029HEPTA/GPS turns into a highly accurate NTP Stratum 1 Time
Server. It is used for the synchronization of computers and industrial networks.
The Time Server supports the following synchronization protocols:
• NTP (incl. SNTP)
• Daytime
• Time
• SINEC H1 time datagram (Activation Key necessary)
Front Side
Rear Side
The Time Server 8029HEPTA/GPS is integrated into a 1U/84HP 19" rack and characterized
by its easy and simple operation. Some of these practice-oriented functionalities are e.g.:
• Complete parameterisation via protected WebGUI access
All required settings for operation can be executed via a password protected WebGUI
also giving an overview of the status of the Time Server 8029HEPTA/GPS.
• LCD-Display and Status-LEDs in the front panel
The LCD-Display and the Status-LEDs make rapidly and easily substantial information
for commissioning, on the operating status and for support matters available if a
problem occurs, even without WebGUI access.
• Monitoring of GPS antenna circuit
An error message is generated when there is a short circuit in the GPS antenna circuit
or an open antenna input.
• Automatic switch-over of summer/winter time (initial setting required)
After initial commissioning there is no user intervention for a correct summer/winter
time changeover for the following years required.
• Automatic handling of the leap second
Should a leap second be inserted in the UTC time, it is recognized by the Time Server
8029HEPTA/GPS via the GPS signal and the leap second is automatically inserted in
the time information.
• Customized extensions possible
The new designed housing concept allows customized system extensions for
additional signal outputs (processed ex-works) easily and fast.

autokey and access restrictions and deactivation of non-used protocols.
Different Management and Monitoring Functions are available as options (e.g. SNMP,
SNMP-Traps, E-mail notification, Syslog-messages including MIB II and private Enterprise
MIB).
Currently the Time Server 8029HEPTA/GPS offers following unlockable functions:
• SINEC H1 time datagram
• Static Routing Table
• Alarming and management features
• IEEE 802.1Q Tagged VLAN

• Easy operation via WebGUI
• LCD-Display (2x40) and Status LEDs on the front panel
• Sync status output via optical coupler
• High freewheel accuracy provided by GPS-supported regulation of the internal
quartz basis
• Completely maintenance-free system
• SyncOFF Timer (reception failure bypassing) for operation free of fault messages
even based on difficult reception conditions
• Redundant multiple validation of the synchronization signal for an error-free and leap
free signal evaluation
• Maintenance-free, buffered backup clock for at least three days

3 Function Principle
This chapter describes the function principle of the Time Server 8029HEPTA/GPS and the
internal relations between the different functional groups.
3.1 Block Diagram
• Firmware Update
A H8 firmware update of the Sync Source (here Module 8024GPS) is completely
controlled by Module 8029HEPTA.
The update file for Module 8024GPS is loaded into Module 8029HEPTA via LAN
through the WebGUI. Then Module 8029HEPTA 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
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.
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.
The data indicated in the display are applicable to updating-cycles such as the WebGUI. An
on-going process is indicated via the display.

3.5 System EXTENSION 1 - 6 (Option)
The system 8029HEPTA/GPS can be equipped with autonomous extension modules for
complex functions (e.g. NTP Time Server Module 8029NTS/M) but also with additional output
hardware for signals generated by the system 8029HEPTA/GPS itself and parameterized by
its WebGUI.
Autonomous extension modules that are only provided with the high-precise time information
for its own function/signal generation by the system have two Status LEDs in the front panel.
Those are assigned via the EXTENSION numbers. These LEDs indicate the according
operation status of the extension module.

4 System Behaviour
This chapter describes the behaviour of the system in special operational phases and
conditions.
4.1 Boot Phase
The boot process of the Time Server 8029HEPTA/GPS starts after turning on the system or a
reset.
This phase can be recognized by the LCD-Display and activated LED test of the Status LEDs
in the front panel.
During the boot process the Module 8029HEPTA boots its LINUX operation system and is
therefore not available via LAN.
The end of the boot process is reached when the LCD-Display changes to the standard picture
and the LED test of the Status-LEDs in the front panel has been finished.
The boot process lasts approx. 30 seconds.
4.2 NTP Adjustment Process (NTP/Stratum/Accuracy)
NTP is a regulation process. After start of the NTP services, automatically processed during
booting, the Time Server 8029HEPTA/GPS requires approximately 5-10 minutes after
synchronization of the Sync Source (Status "SYNC") until NTP is set to the high accuracy of
the Sync Source (here Module 8024GPS) and reaches the optimized operation condition of
STRATUM = 1 and ACCURACY = High.
The decisive factors here are accuracy of the synchronization source and the appropriate
synchronization condition of the Sync Source.
4.3 Reset-(Default) Button
The Time Server 8029HEPTA/GPS can be reset by the Reset-(Default) Button behind the
front panel of the board. The Reset-(Default) Button is accessible with a thin object through
the small drilling in the front panel.
The button triggers different functions depending on how long it is pressed:
Duration
Function
< 1 sec.
No action
1 - 9 sec.
After releasing a system wide hardware reset is triggered
>= 10 sec.
After releasing a FACTORY DEFAULT followed by a REBOOT is
triggered after approx. 10 seconds
