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 Frank- furt/Germany transmits the reference time of the Federal Republic of Germany. This time reference is either the Central European Time (Mitteleuropäische Zeit, MEZ) or... -
Page 7: Overview
Overview Several product lines of radio remote clocks for IBM compatible computers are available from Meinberg. While all of them are using a common software interface, different computer architectures require different board layouts. So the board called PC32 can be installed in every standard PC with ISA or EISA bus. PC32E is the name of the corresponding eurocard size board for 19"... -
Page 8: Installing The Pc32 In The Computer
Installing the PC32 in the Computer Programs can read data from or write data to the board using 2 I/O ports from a block of four addresses. The base I/O address can be set up in a wide range using the DIL switch on the board. -
Page 9: Connectors And Leds In The Rear Panel
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 dis- play or some other external device. The string is sent out once per second, once per minute or if requested by an incoming ASCII '?'. -
Page 10: Activating The Pulse Outputs
Activating the Pulse Outputs The radio clock PC32 generates active high TTL level pulses whenever a second or minute changes. A jumper block on the board can be used to wire the TTL outputs (0..5V) to some of the connector pins. In this case, absolute care must be taken if another device is connected to the port, because voltage levels of -12V through +12V (as commonly used with RS-232 ports) at TTL outputs may damage the radio clock. -

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 12: Using Pcpsinfo.exe
If the utility diskette is inserted in drive A: use the following command to copy the files and subdirectories from the diskette to the hard disk: XCOPY A:*.* /S Using PCPSINFO.EXE After the board has been installed in the computer the program PCPSINFO.EXE should be run in order to see if the board has been properly installed. - Page 13 The upper part of the screen shows information about the resident driver (if the driver has been installed). These information include the ID string of the resident driver with the driver revision number, the number of the software interrupt used to control the resident driver and the last recent date/time the driver has read from the board.
- Page 14 The serial interface transmits the date/time/status string known from other Meinberg radio remote clocks. The serial parameters can be setup by menu if the key F4 is being hit. The line Last Sync: shows the time last synchronization has been achieved. If the clock runs synchronous with DCF77 this field is updated once every minute.

Page 16: Controlling The Resident Driver
Controlling the Resident Driver If the resident driver PCPSDRV.COM has been installed, some of the utility pro- grams can be used to control the way it works. The programs described below show a few help lines when they are called without command line parameters. DRV.EXE temporarily disables the resident driver´s access to the board. -

Page 19: 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 20: 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. -
