Execute Setup.exe and choose the installation directory. By default, the installation directory is: C:\Program Files\Meinberg\MbgMon Then shut down the computer, install the Meinberg radio clock plug-in board into a free slot and reboot. Now you are asked to install a driver. The driver file MEINBERG.INF can be found in the subdirectory Driver\PnP... -
Page 6: General Information
General information The satellite clocks made by Meinberg have been designed to provide extremly precise time to their users. The clocks have been developed for applications where conventional radio clocks can´t meet the growing requirements in precision. High precision available 24 hours a day around the whole world is the main feature of the new system which receives its information from the satellites of the Global Posi- tioning System. -

250m. Power is supplied to the unit DC insulated across the antenna cable. Optionally, an overvoltage protection and an antenna distributor are available. The antenna distributor can be used to operate up to 4 Meinberg GPS receivers using a single antenna/converter unit. -
Page 9: Asynchronous Serial Ports
Asynchronous serial ports Two asynchronous serial interfaces (RS232) called COM0 and COM1 are available to the user. Only COM0 is available at the rear panel slot cover, COM1 must use another submin-D connector which can optionally be connected to the 5 pin jumper block on the board. -
Page 10: Dcf77 Emulation
DCF77 emulation The GPS169PCI satellite clock generates TTL level time marks (active HIGH) which are compatible with the time marks spread by the German long wave transmitter DCF77. This long wave transmitter installed in Mainflingen near Frankfurt/Germany transmits the reference time of the Federal Republic of Germany: time of day, date of month and day of week in BCD coded second pulses. -

This port can not be used as serial port for the compu- ter. Instead, it can be uses to send out Meinberg's standard time string to an external device. A DIL switch on the board can be used to wire some TTL inputs or outputs (0..5V) to some connector pins. -
Page 12: Installing The Radio Clock
Installing the radio clock Every PCI board is a plug&play board. After power-up, the computer's BIOS assigns ressources like I/O ports and interrupt lines to the board, the user does not need to take care of the assignments. The programs shipped with the board retrieve the settings from the BIOS. -
Page 13: Mounting The Antenna
Mounting the antenna The GPS satellites are not stationary but circle round the globe in a period of about 12 hours. They can only be received if no building is in the line-of-sight from the antenna to the satellite, so the antenna/converter unit must be installed in a location from which as much of the sky as possible can be seen. -
Page 14: Firmware Updates
the new almanac is complete and the system switches to Warm Boot mode scanning for other satellites. In the default mode of operation, neither pulse outputs nor the serial ports will be enabled after power-up until synchronization has been achieved. However, it is possible to configure some or all of those outputs to be enabled immediately after power-up. -
Page 15: 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 16: Timecodes
Timecodes The transmission of coded timing signals began to take on widespread importance in the early 1950´s. Especially the US missile and space programs were the forces behind the development of these time codes, which were used for the correlation of data. -
