Note
Completely independent from the "classic" receiver configuration
shown here, the connection notes in the installation instructions for
the RC components involved must always be observed. Modern fly-
barless systems, for example, often now have a sum signal input for
PPM (SUMO for Graupner HoTT receivers) or SUMD (digital sum
signal), so that a single connection cable is sufficient to establish a
connection. However, the desired sum signal must be selected in
the receiver as described at the end of the "Setting & data view"
section of the "Telemetry" menu.
