1 System Description: 6842 GPS Slim Line (1U)

The proven and tested

hopf

System 6842 GPS has been integrated into an 1U/84HP
housing (U = height unit) in the Slim Line version, which is geared to meet today’s computer
and network technology requirements. In this way, the wide functionality range of the 3U
housing designs is maintained in spite of the reduction in size. In addition, status LEDs to the
front and rear and status (error) relays provide information about the equipment’s operating
condition.

The full modularity of the System 6842 GPS is available in the 1U design. This allows tailor­made solutions to be realized with the System 6842 GPS. The System can be extended
using Function Boards which can be added by the customer. In this way, functionality can be
easily upgraded on site at low cost. Function Boards can also be exchanged directly on site.

A high degree of flexibility and availability is achieved combined with high reliability and
complete freedom from maintenance.

A variety of Function Boards is available to cover almost every requirement, from the simple
pulse output to the NTP time server.

The Slim Line version of the

hopf

System 6842 GPS will further complement the innovative

product range of

hopf

Elektronik GmbH.

1.1.5 System Bus 6000

The System Bus, consisting of the Bus Board with VG ledges, via which the Control Board
6842 and the Function Boards are connected, can be found in the System 6842.

The System Bus serves to provide:

• Distribution of the time information

• Communication between Control Board 6842 and the Function Boards

• Transmission of the regulated second pulse (PPS). This serves to synchronize the

data output of the implemented Function Boards

• Distribution of the regulated DCF77 pulse (generated by the Control Board 6842)

• Circular auto-reset circuit for ongoing verification of the System Bus Function Boards

to be found in the System

• Power supply for the installed boards

Each active Function Board (transmit and receive) which is linked to the System Bus has a
SEND LED. This LED signals which of the Function Boards is active on the System Bus.

Function Boards which only receive data from the System Bus do not have a SEND LED.

1.1.6 Function Board Slots

Up to two Function Boards can be implemented in the System 6842 GPS Slim Line (1U).

As a basic principle, the slot can be freely selected for each 'Function Board' / 'System Bus
Function Board'.

Exceptions of the slot selection can be found in Chapter 6 Function Boards

Only boards that have been adapted for the 1U Slim Line System can be used in these slots.

Slots that have been prepared for special functions are identified with the letters "A" and

"B".

1.1.7 Temperature-controlled Forced Ventilation

The clock system has two temperature-controlled fans to prevent the operating temperature
rising above the allowed limit as a result of thermal coupling with equipment mounted in the
control panel.

These fans are mounted on the side ventilation apertures and switch in when the
temperature in the equipment reaches approx. 45°C.

The ventilation apertures on the left and right hand sides must not be
covered. Otherwise, active ventilation is ineffective and inadequate
convection and/or thermal coupling with surrounding equipment may cause
the temperature to rise above the equipment’s maximum permissible
operating temperature.

The operational sign indicates the direction in which the local time differs from the world
time:

'+' Corresponds to East of the Null Meridian (Greenwich)
'-' Corresponds to West of the Null Meridian (Greenwich)

Since most countries of the world count their time offset in whole hours, the input is also in
one hour steps:

e.g. + 05:00 or - 11:00

However, some countries also use smaller time intervals. Therefore it is also possible to
input the data in one minute steps:

e.g. + 05:30 or - 08:45

The time offset always relates to the local standard time (winter time),
even if commissioning or input of the time offset takes place during summer
time.

Example for Germany:

UTC Local Time

Time offset to

be set:

Comment

13:00:00 14:00:00 (winter time) +01:00
13:00:00 15:00:00 (summer time) +01:00

The time offset of two hours is
made up of
+01:00h time offset and
+01:00h for the summer time
offset (changeover points of time
must be set for this purpose).

4.1.1.3 Input ST/WT Changeover Points of Time

This input is used to define the points of time at which the changeover is made to summer
time or to winter time throughout the course of the year. The hour, weekday, week and
month in which the ST/WT changeover (summer time / winter time changeover) is to take
place are given here. The exact points of time are then calculated automatically for the
current year.

The parameters are selected in such a way that the changeover can take place at any point
of time. For control purposes, the exact date for the current year is indicated in the Show
functions.

If the ST/WT changeover is not to be activated all values have to be entered as 0. The
System 6842 then only operates with the standard time (winter time) set via the time offset.

4.1.1.4 Input Position

The geographical position of the equipment is entered with this function. This function is
helpful during the first commissioning and shortens the first synchronization of the GPS
receiver.

Selection frame:

S E T P O S I T I O N
Y / N _

Input frame:

L T . N 5 1 ° 1 2 , 3 6 5 1 '
L N . E 0 0 7 ° 3 7 , 8 4 2 6 '

The entries for the latitude and longitude positions take place in degrees and minutes.

The operational sign for the degrees of latitude - LT. is:

N Northern hemisphere
S Southern hemisphere

and for the degrees of longitude - LN.:

E East of the Null Meridian (Greenwich)
W West of the Null Meridian (Greenwich)

The latitude position is entered first under PGG°MM,SSSS, where the meanings are as
follows:

P N or S, North or South
GG Degrees of Latitude from 00 - 89
MM Minutes of Latitude from 00 - 59
SSSS Minutes of Latitude decimal places 0000 - 9999

There then follows the entry of the longitude position under pGGG°MM,SSSS, where the
meanings are as follows:

p E or W, East or West
GGG Degrees of Longitude from 000 - 179
MM Minutes of Longitude from 00 - 59
SSSS Minutes of Longitude decimal places 0000 - 9999

The position of

hopf

Elektronik GmbH is given in the above example.

The entry is completed by pressing the ENTER key.

In order to speed up the synchronization of the GPS receiver it is sufficient for the position to
be input to an accuracy of 1-2 degrees (without minutes or decimal places).

If the position is unknown 0 should be entered in all places.

If the position is not known during commissioning and the antenna position
is adverse, the GPS evaluation should be changed from Position-fix to 3D
(Chapter 4.1.4.4 3D / Position-fix GPS Reception and Synchronization
Mode). Otherwise this may lead to the output of an imprecise time when
synchronizing with less than four satellites.
After calculating the actual position by means of the clock system, the GPS
evaluation can be changed back to Position-fix.
