7 Connectors and LEDs in the rear slot cover
7.1 Configuring the 9 pin connector
By default only the signals needed for the serial port COM0 are mapped to the pins of the connector. Whenever
one of the additional signals shall be used, the signal must be mapped to a pin by putting the appropriate lever
of the DIL switch in the ON position. The table below shows the pin assignments for the connector and the DIL
switch lever assigned to each of the signals. Care must be taken when mapping a signal to Pin 1, Pin 4 or Pin 7
of the connector, because one of two dierent signals can be mapped to these Pins. Only one switch may be put
in the ON position in this case:
Pin 1: DIL 1 or DIL 8 ON
Pin 4: DIL 5 or DIL 10 ON
Pin 7: DIL 3 or DIL 7 ON
Those signals which do not have a lever of the DIL switch assigned are always available at the connector:

7.2 Installing the GPS170PEX in your computer
Every PCI Express board is a plug&play board. After power-up, the computer's BIOS assigns resources like I/O
ports and interrupt numbers 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.
The computer has to be turned o and its case must be opened. The radio clock can be installed in any
PCI Express slot not used yet. The rear plane must be removed before the board can be plugged in carefully. The
computers case should be closed again and the antenna can be connected to the coaxial plug at the clock's rear
slot cover. After the computer has been restarted, the monitor software can be run in order to check the clock's
conguration.The computers case should be closed again and the antenna must be connected to the appropriate
connector.
