Page 5: General Information About Dcf77
General Information about DCF77 The radio 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 Central... -
Page 6: Overview
Overview The radio clock PCI509 is designed to operate in computers with PCI bus. An external ferrit antenna makes the signal from DCF77 available to the on-board long wave receiver. The demodulated time marks are decoded by the clock´s microprocessor. If no errors are detected in the current time message an additional plausibility check against the previous time message is performed. -

This port can not be used as serial port for the computer. Instead, the clock uses the port to send out Meinberg's standard time string in order to control an external display or some other external device. The string is sent out once per second, once per minute or if requested by an incoming ASCII '?'. -
Page 8: Pin Assignments Of The 9 Pin Connector
Pin Assignments of the 9 Pin Connector When the clock is being shipped, only the signals needed for the serial port are gated to their pins at the 9 pin connector. If another signal shall be available outside the computer, the corresponding lever of the DIL switch on the board must be set to the ON position to connect that signal to its associated pin. -

Assume the current drive is C: and the new subdirectory is to be created on the current drive, create that subdirectory (e.g. called MEINBERG) using the command MD \MEINBERG from the DOS command line. - Page 11 MONO Force monochrome display even if color display installed. May increase the readabi- lity on LC displays often used with laptops. Displays a message how to setup port address and how to use the program. Output can be redirected to printer ( append ">LPT1" to the command line) or file (append ">filename").
- Page 12 The serial interface transmits the date/time/status string known from other Meinberg radio clocks. The field labeled Date/Time: displays the radio clock's current date and time. The line Last Sync: shows the time last synchronization has been achieved.

Page 17: Replacing The Lithium Battery
Replacing the Lithium Battery The life time of the lithium battery on the board is at least 10 years. If the need arises to replace the battery, the following should be noted: ATTENTION! Danger of explosion in case of inadequate replacement of the lithium battery. -
Page 18: Format Of The Meinberg Standard Time String
Format of the Meinberg Standard Time String The Meinberg Standard Time String is a sequence of 32 ASCII characters starting with the STX (start-of-text) character and ending with the ETX (end-of-text) charac- ter. The format is: <STX>D:dd.mm.yy;T:w;U:hh.mm.ss;uvxy<ETX> The letters printed in italics are replaced by ASCII numbers whereas the other characters are part of the time string. -
