Scantrol application does not receive speed measurements

You have a system configured as a twin trawl and put only one trawl in water. Scantrol does not receive anymore speed measurements from the speed sensor.

Scala2 2.10.x and later: If the system is configured to operate on a twin trawl with one speed sensor on each trawl, but only one trawl is put in water: make sure that the speed sensor in water is the one from the first trawl, configured with a node between 10 and 13. If not, Scala2 will not send any speed measurements.
