Behaviour in case of reception interferences

The composite signal converter measures the signal quality and thus also recognises reception interferences.

Since channels 1 - 4 are mainly used for general control of models, they are specifically described.

Interferences on channels 1 - 4

For these channels, verification of a valid pulse width (between 1 and 2 ms) is performed. If an error is recognised, the
composite signal is generated with the last valid value.

When the error rate exceeds the measure for proper reception, the composite signal converter does not output any
composite signal anymore and activates the red LED. Now the reception problem can be recognised by the down-
stream logic and no reception problems are concealed.

If the input signal is valid again, the red LED goes out and a composite signal is generated.

Interferences on channels 5 - 8

If the reception interference only acts on channels 5 - 8, a composite signal continues to be generated for channels
1 - 4 and channels 5 - 8 are output with an invalid pulse length.

Thus, it is possible to continue to control the model, but the interference can be recognised by a downstream logic at
channels 5 - 8.

When the input signal is valid again, a regular composite signal is output.

d) Interface Connection

For a connection of the combiboard to the control
board of the QuadroCopter, the combiboard comes
with a 26-wire foil cable that must be connected to
the connection strip for the broad interface cable
(“X10”).

Late, when installing the combiboard in the
QuadroCopter, observe that the two connection
strips for the broad interface cable (combiboard and
control board) are exactly across from each other.

Connection is performed in the same way as a con-
nection between the two motor driver boards and
the control board.
