Page 5: General Information About Dcf77
General Information about DCF77 The radio remote clocks made by Meinberg receive the signal from the long wave transmitter DCF77. This long wave transmitter installed in Mainflingen near Frankfurt/ Germany transmits the reference time of the Federal Republic of Germany. This time reference is either the Central European Time (Mitteleuropäische Zeit, MEZ) or the... -

7-digit LED display and a time/date switch. An asynchronous serial port is available which can be used to read out information on date, time, and status. The Meinberg standard time string can be sent automatically whenever a new second begins (default) and/or the host has sent a request character. -
Page 8: Antenna And Lf Receiver
Antenna and LF Receiver An external ferrit antenna is used to receive the signal from DCF77. Optionally, a weather-proof antenna is available which can be mounted outdoor. A coaxial cable which can be up to more than 100 meters in length is used to pass the antenna's output signal to the on-board LF receiver where it is demodulated by a synchronous detector with automatic gain control. -
Page 9: Buffered Real Time Clock
Buffered Real Time Clock If the board's power supply is turned off, a gold cap capacitor on the board lets the real time clock keep time and status for typically 300 hours (150 hours minimum). This capacitor does not need any maintenance. Alternatively, the clock can be ordered with a lithium battery which has 10 years of life time guaranteed. -

Page 11: Customizing The Ua32S Configuration
Customizing the UA32S Configuration The chapters below describe how to configure the serial port parameters and the output switching characteristics using the byte tables in the on-board EPROM. The configurati- on parameters start address is 0E00h. All numbers are in hex notation (rsp. packed BCD), e.g. -
Page 12: Listing Of Default Configuration
Three tables WERKT1, WERKT2, and WERKT3 are available to define 3 turn-on/ turn-off cycles per output for working days (Monday through Friday) and three additio- nal tables WOENDT1, WOENDT2, and WOENDT3 for turn-on/turn-off cycles at the weekend (Saturday and Sunday). Each table has an entry for one turn-on/turn-off cycle per output. - Page 13 ; 2.
