Example
Figure 40 shows a small set of filter rules:
Figure 40
These rules have the following effect:
•
GPRMC sentences are passed only when received on input 1 and they are routed to output 1 and to
the PC.
•
HCHDT sentences are passed from input 2 and routed to the PC. Only every 5
th
sentence is passed.
•
IIMWV and IIMTW sentences are passed from input 3 and routed to the PC.
•
VHVHW sentences are passed only as the result from a conversion (VTG -> VHW) and thus passed
from input C to output 1 and the PC.
None of the sentences are sent to the wireless interface (W) and the default route is applied on sentences
that are not in the filter list.
