8.2 Configuring Auxiliary Sensors for Redundant Information
Auxiliary sensors can input redundant auxiliary information into the 6205s2. This will cause a significant
data alignment problem as the sequential sonar data packets will be inconsistently stuffed from multiple
sources. This section defines redundant auxiliary information as multiple sources of the same class of
auxiliary information (e.g., roll, pitch, heading). This redundancy problem is generally caused by two
sensors supplying the same message string and two sensors supplying the same information but from
different messages. The following subsections describe each problem and the configuration that should
be done to remedy it. In the event the auxiliary sensors cannot be reprogrammed to output select data
messages, the Discover software should be configured so that only one specific source of information is
used.
8.2.1 Two Different Sensors Supplying the Same Message
If two different sensors are outputting the same message (NMEA HDT, for example) and the sensors
cannot be reprogrammed, then the Discover Bathymetric Software must be configured to accept the HDT
information from one of the sensors only. To do so, use the procedure described below.
NOTE:
The configuration described below only works if there are two
sensors outputting the same specific message (like HDT). It does not work
for different messages that contain the same information (i.e., OCTANS
and HDT). Refer to Scenario 7.3.2 in this case.
