Brief Description of System 7001
The hopf System 7001 is a microprocessor system with a modular structure. Each main
board within this Eurocard system has its own microprocessor. So time-critical tasks can be
solved easily on the boards themselves. The modular concept enables individual configura-
tion of systems according to customer specifications. Moreover this concept guarantees
simple servicing.
Board 7020
This board replaces the 7015 Control Board and, as a control board, forms part of the basic
version of the Master Clock System 7001. It has been prepared for the evaluation of different
synchronisation sources such as DCF77, GPS, serial data strings or IRIG-B
can be used for keypad- and display control and for bus communication with other boards in
the system. It is equipped with the standard quartz pulse generator and can also be fitted
with a oven-stabilized quartz generator to attain better freerunning properties.
Board 7112 / 7121
With the optical coupler or relay board 24 bits can be emitted potential-free. 8 potential-free
inputs are available for output control. The optical coupler and relay boards are pin-
compatible with each other.

• Board 7121 relay board
Board 7201
The serial interface board 7201 emits a data string either via an RS232c (V.24),
RS422 (V.11) or a passive TTY interface. The transmission format and the method of output
are adjusted on the DIP-switch on the board.
Board 7210
This board receives the transmission data string TxD from the main board 7200 / 7201 or
7220 / 7221 in TTL level and duplicates this via 4 x RS232-, 4 x RS422- and 4 x active or
passive TTY interface.
Board 7221
On this serial interface board there is a full-duplex interface and 7 duplicated transmission
data strings via RS232 and RS422 hardware.
Board 7245
On this board there is a serial full-duplex interface and 4 multipliers for the transmission line
TxD. The interface hardware is designed for the RS232 and RS422 level. All the interfaces
are set up potential-free to each other and to the subordinated logic. In addition there are 4
potential-free minute pulses.
Board 7265
On this board there are 4 analogue switches each with 4 inputs. Connected to these inputs
are the signals IRIG-B 12x, IRIG-B 00x and PPS pulse created on the board itself and also
an external input for the frequency boards 7530 and 7550. The inputs are switched through
to the outputs via DIP switches. The output signals are at BNC connectors.
