2.3.2 Adjustable Multi-Source Modes
The sync. sources are connected to the synchronisation channels of the 7020RC control
board. The selection and connection of the various synchronisation channels is described
below. Only the described combinations of synchronisation channels are available.
A re-configuration of these modes automatically triggers a RESET after configuration in the
system.
2.3.2.1 Multi-Source with GPS (Channel 1) and Master/Slave-String (Channel 3)
The combination of GPS and Master/Slave-String can be selected via the following two bit
combinations in the
"Synchronisation Settings Byte"
. The primary and secondary sources
can also be assigned. After the initial setting of one of the two bit combinations a System
Reset is carried out automatically. When there is a changeover within this multi-source mode
no System Reset is carried out and the system then continues with quartz system status.
