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 tailor-
made 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 following steps are to be carried out:
• Place the rack in the control panel and fix to the mounting brackets on the front
side of the rack using 4 screws.
The side ventilation apertures on the right and left hand sides must not be
covered. Otherwise active ventilation will not be effective and lack of
convection and / or thermal coupling with surrounding equipment may give
rise to an excessive equipment operating temperature.
• Ensure that there is sufficient space between the connection side of the rack and
the control panel to allow for the connection of cables to the System.
2.2 Earthing
The System 6842 GPS Slim Line (1U) is usually earthed via the PE cable of the power
supply.
