Multiple client dashboards can be connected to the same sensor in a master/slave configuration. This
feature provides redundancy around the vessel bridge where it is often important for multiple crew
members to have access to the Mini RadaScan data. In order to enhance safety during operations, slave
consoles are only able to view the current status of the sensor and are unable to gain service access,
start tracking or change the blanking zone. Any slave can request to be the master.
When the console is connected to a sensor and navigating, it autonomously collects detailed logs. These
logs offer valuable information to the support team to quickly diagnose any issues reported by
customers.

Multiple Sensor/Multiple Target Operation
The Mini RadaScan sensor automatically detects and identifies responders within the maximum range
and where a line of sight exists between the sensor and a responder. Each responder has a unique ID
and will respond to multiple sensors simultaneously allowing multiple vessels to operate in the same
region independently (Figure 11).
Figure 11 – Multi-responder multi-sensor operation
As illustrated in Figure 11, a DP operator can track more than one responder at the same time, whilst
another DP operator can track one or more of the same responders. Both operators can track the
same responders simultaneously.
The DP operator should refer to the Mini RadaScan documentation or contact the service team for
details to make sure the DP telegram data matches expectations of their DP system.
8.3
Mini RadaScan Interoperability and Compatibility
The performance of the Mini RadaScan is determined by the target choice. There are two formats of
target currently in field, a transponder and a responder as shown in Figure 12.
The transponder is an older generation target and its modulation type differs from the currently
manufactured responder. The modulation type of the transponder is referred to as series 1, the
modulation type currently used is referred to as series 2.
The responders are the latest generation of target and are capable of being programmed as series 1 or
series 2 or series 3. Responders are much smaller, lighter and give better performance than the earlier
transponders. The older generation transponders may not provide the maximum range performance
of the Mini RadaScan sensor.
