1 General
The hopf Sync Module 8024GPS is a GPS Module for the reception and evaluation of GPS
signals for high-precision signal generation and output of time information. In combination with
other hardware output modules, rack vesions and power supplies the module can be "custom-
tailored" set-up and used for various applications. The configuration of the GPS settings and
the signal generation is made via the serial remote interface.
Some of the Sync Modules 8024GPS basic functions:
•Simple configuration using hmc software on remote interface
•Remote interface (Serial-Remote) on the front panel (RS232 format)
•Status LEDs on the front panel
•Status optical coupler on the front panel
•High freewheel accuracy through GPS-supported regulation of the internal quartz base
•Completely maintenance-free system
•SyncOFF timer (reception failure bypassing) for operation free of fault messages - even
in difficult reception conditions
•Redundant multiple validation of the synchronization signal for fault-free and leap-
free signal evaluation
•Maintenance-free, buffered back-up clock for more than three days
Accessories supplied:
•Serial programming cable KA6870 (2m, 9-pole socket to 9-pole socket) to connect
to a PC.
As the Module 8024GPS is supplied in system build-ups, the build-up of the unit and the
system-specific connections and signal outputs are documented in the accompanying manual.
Not all signal outputs parameterizable via the hmc software are always
available as physical outputs for the different system variants.
The available functions and their appropriate physical outputs are stated in
device-specific manual.

2.2.3 Status Optical Coupler
The status optical coupler provides a potential isolated switching contact for monitoring the
modules synchronization status.
Function:
Status output via 3-pole terminal with selection of the desired synchronisation status at which
reporting is to be activated:
Optical coupler:
•Selected status or better achieved –Optical coupler switched through
•Selected status not achieved –Optical coupler blocked
The desired reporting status is set via the hmc software.
2.2.4 Serial-Remote Interface for hmc software
The connection to a PC’s RS232 serial interface is made by means of the KA6870 interface
cable supplied.
The Serial-Remote interface for the configuration of the module is located on its front panel.
The transmission line (Tx) and reception line (Rx) have status LEDs which signal the activity
on the respective interface line.
No further configuration of this Serial-Remote interface is necessary.
2.3 Back-up Clock
The module has a maintenance-free, buffered backup clock for at least three days.
After a power failure the clock starts with the internal back-up clock information unless valid
time information was available beforehand.
2.4 Voltage Feed
The voltage feed takes place via the integrated power supply in the device.
2.5 Further Signal Outputs
Further available signal outputs of the respective system are stated in the accompanying
manual of the specific-device.

3 hmc ( hopf Management Console) software
This Chapter describes the operation and functionality of the hopf Management Console
(further abbreviated with hmc software) for the Sync Module 8024GPS.
3.1 Installation on Microsoft Windows
The installation routine is started via a double click on
HMC_v01.13_b1190_Windows_install.exe . A query for the installation routine's language will
appear - select English and click OK.
The installation wizard has been started now. In the lower area there are three buttons: Back,
Forward, Cancel. The Back button allows returning to previous steps at any time, in order to
see or change the settings there. If the settings in a step of the installation seem to be in order,
the button Forward will lead to the next step. The Cancel button allows leaving the installation
wizard at any time, in which case no installation of the hmc software will be performed on the
computer.
Step 1, The Welcome Screen
Information is shown, partly of a legal kind concerning the
licence conditions for the hmc software. Activating the Forward
button implies having read the information and accepting the
licence conditions.
Step 2, Installation Directory Selection
Instead of the standard installation directory, on a English
language Windows Installation this would be C:\Program
Files\Hopf, it is possible to install the hmc software into any
other directory. This allows the parallel installation of different
versions.
Step 3, Finalization
In this place, the user is informed that the next activation of the
Forward button will start the hmc software installation process,
following the settings made in the previous steps. In case of
concordance with these settings, the installation process is to
be commenced by activating the Forward button.
Step 4, The Installation Process
A progress bar indicates how much of the installation process
has been accomplished. It is necessary to wait until the
installation process is finished.
Cancel allows to cancel the process at any time. In this case, a
complete installation will not be performed.
Step 5, Confirmation
The user is informed that the hmc software has been
successfully installed. Activating Finish will close the installation
wizard. The hmc software has now been prepared for use and
may be started.

3.5.1 Configuration / Plausibility Check
A reconfigured and not saved parameter is shown with a black changing-asterisk in the tab
and in the device tree.
In case of an invalid input, a red asterisk will be shown and the causing input control is
highlighted with pink background colour.
Transmitting values to a device is not possible whenever an invalid input is present.
3.5.2 Transmit Value Changes
Pushing the button , transmit changes to device, all present configuration value changes
that have not yet been successfully transmitted to the device are transmitted immediately. The
action is going to fail if there are any invalid inputs in any of the device's tabs. In that case, the
effort will result in an error dialog. Transmission will always affect all changes in all tabs.
3.5.3 Read from Device
The button , read all values from device, causes a complete re-read of all values from the
device, losing all eventually present changes that have not yet been transmitted.

Pushing the button , undo all changes, will discard all eventually present changes that have
not yet been transmitted without reading the new state from the device.
3.5.5 Load a Configuration File
Pushing the button , load a configuration file, starts a file-open-dialog for choosing a
configuration file to load into the device. This file must have been saved using the exact same
device driver, otherwise loading the configuration is going to fail showing an error dialog.
This file must have been saved using the exact same device driver.
3.5.6 Save the Current Configuration
Pushing the button , save the current configuration, starts a file-save-dialog for defining a
target file to which the currently active configuration of the device will be saved for later loading
into the same or another device using the exact same device driver.
