correctly. The device should only be operated with the voltage supply
indicated on the identification label.
The device should only be operated by qualified staff or employees who
have received specific instruction.
If a device must be opened for repair, this should only be carried out by
employees with appropriate qualifications or by hopf Elektronik GmbH.
Before a device is opened or a fuse is changed all power supplies must
be disconnected.
If there are reasons to believe that the operational safety can no longer
be guaranteed the device must be taken out of service and labelled
accordingly.
The safety may be impaired when the device does not operate properly
or if it is obviously damaged.
CE-Conformity
This device fulfils the requirements of the EU directive 2014/30/EU
"Electromagnetic Compatibility" and 2014/35/EU "Low Voltage Equipment".

1 GPS - NTP Time Server 8030HEPTA/GPS
By GPS time synchronization and the worldwide used time protocol NTP (Network Time Pro-
tocol) the Time Server 8030HEPTA/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)
•IEEE 1588 Precision Time Protocol (PTP) (Activation Key necessary)
Front Side
Rear Side
The Time Server 8030HEPTA/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 8030HEPTA/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 prob-
lem 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
8030HEPTA/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 addi-
tional signal outputs (processed ex-works) easily and fast.

A superior security is guaranteed via available coding procedures such as symmetric keys,
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).
The Time Server 8030HEPTA/GPS currently has unlockable features that are described in
chapter 4.5 Activation of Functions (Activation Key):
•SINEC H1 time datagram
•Static Routing Table
•Alarming and management features
•Network Interface Bonding/Teaming
•IEC 62439-3 Parallel Redundancy Protocol (PRP)
•IEEE 802.1Q Tagged VLAN
•IEEE 1588 Precision Time Protocol (PTP)
A few other basic functions of the Time Server 8030HEPTA/GPS:
•The Time Server 8030HEPTA/GPS operates as NTP Server with Stratum 1
•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
Software supplied:
• hmc ( hopf Management Console) Software

2.2.6.1 MAC-Address for ETH0/ETH1
Each LAN interface is clearly identifiable on the Ethernet via a unique MAC Address (hardware
address).
The MAC addresses given for the LAN interfaces can be read in WebGUI of the appropriate
board or be evaluated via the hmc Network Configuration Assistant.
The MAC address for ETH1 is incremented hexadecimal by 1 to the MAC address of ETH0.
Example:
•MAC address ETH0 = 00:03:C7:12:34:59
•MAC address ETH1 = 00:03:C7:12:34:5A
The MAC address is uniquely assigned for each LAN interface by the company hopf El-
ektronik GmbH.
hopf Elektronik GmbH MAC addresses begin with 00:03:C7:xx:xx:xx.

3 Function Principle
This chapter describes the function principle of the Time Server 8030HEPTA/GPS and the
internal relations between the different functional groups.

•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.
3.2 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.

3.5 System EXTENSION 1 - 8 (Option)
System 8030HEPTA/GPS can be expanded with additional modules ex works. Therefore four
extension slots are available.
Each extension slot can either be equipped with one NTP time server module 8030NTS/M
(each with two GigaBit LAN interfaces) or max. two output modules.
Additionally implemented NTP time server modules 8030NTS/M are mutually independent and
are going to be parameterized via their WebGUI. The operating status of each module
8030NTS/M will be displayed via 2 status LEDs on the front panel which are assigned to the
particular module 8030NTS/M via the related EXTENSION number. If the application is exclu-
sively equipped with modules 8030NTS/M, max. 4 mutually independent modules 8030NTS/M
can be implemented.
Output modules issue signals of the internal signal generators of module 8030HEPTA via var-
ious electrical levels or via fiber optic. Parameterization of the particular signal generator can
be done via WebGUI of module 8030HEPTA. Status of the output modules will not be moni-
tored via status LEDs on the front panel. If the clock system is exclusively equipped with output
modules, max. 8 output modules can be implemented.

tary instruction.
