System 7001 GPS/DCF77

Radio Controlled Clock System

The system 7001 was developed to take over complex tasks. It supplies interfaces for the property management, personnel times recording; synchronises computers, networks and fax machines, supplies pulses for control mechanisms, takes over switching functions, supervises mains frequencies and many more. Due to its modular design it can be configured for every possible use, and it can be stocked up in case the conditions for its use have changed.

Contrary to individual solutions a central clock system has considerable advantages. The main arguments are:

• Only one antenna is required
• In case of reception failures all connected devices are supplied with the same time

Apart from the base system there are plug-in boards with own processors for the required interfaces, which can be plugged into the base system in any configuration. The individual boards communicate via a serial bus system and the control board 7015 centrally synchronises and supervises them.

The Base System

is built into a 19" module carrier with 3 HE. It contains the voltage supply, the control- and receiver board 7015, a 2x40-digit VDF-display and a keypad.

The Receiver

Optionally the system will be synchronized by GPS sattelites or by the DCF77-Signal. The receptors distinguishes itself by the accuracy and the availability of the receiving signals (see GPS-Info and DCF77-Info). All further boards are exchangeable one below the other.

The Control Board 7015

This board contains all the modules required for controlling the system 7001, i.e.:

• microprocessor unit with RAM, EEPROM, buffered backup clock, display-, keypad-, and bus driver
• potential free GPS-receiver
• or potential free DCF77-receiver
• serial RS422-interface for the synchronisation of further 7000 systems as substations
• GPS/DCF77-controlled VCO for good freerunning qualities of the system in case of a failure of the GPS-signal
