2.1.1 GPS Antenna Connection
The coaxial cable of the GPS antenna equipment is connected to the BNC socket marked
"GPS Antenna"
on the front panel. Further specifications concerning the installation of the
antenna equipment, such as cable lengths and cable types, can be found in the document
titled "GPS Antenna Equipment".

2.1.3 Status Optical Coupler
The status optical coupler provides a potential isolated switching contact for monitoring the
Board’s synchronization status.
Status output via 3-pole terminal with selection of the desired system status at which
reporting is to be activated:
Optical coupler:
•
Selected status or better achieved – Optical coupler switched through
•
Selected status not achieved
– Optical coupler blocked
The desired reporting status is set via the remote software.
2.1.4 Remote Interface
The connection to a PC’s RS232 serial interface is made by means of the KA6870 interface
cable supplied.
The remote interface for the configuration of the Board is located on the front panel of the
Board. The transmission line (Tx) and reception line (Rx) have status LEDs which signal the
activity on the respective interface line.
No further configuration of this remote interface is necessary.
