b) Composite Signal Output
The composite signal converter outputs the formed
composite signal (SuS) at the upper contact of the
“X14” connection.
This composite signal consists of so many single
signals as measured at the inputs.
For example, if a 6-channel receiver is used, the
composite signal also has 6 channels.
Channel number recognition is performed via the
valid signal measurement at the inputs.
The connections "SuS" and "GND" must be con-
nected to the respective connections of the mother-
board (figure 16b) in the QuadroCopter.
Ensure correct polarity for the connection of the
two pin contact strips.
c) LED Status Display
The composite signal converter has a green and a
red LED for status display.
A green LED (LD1) indicates that the electronics
are in normal operation. This means that servo sig-
nals can be measured, and if required a composite
signal can be generated.
When the green LED goes out, there is a basic
interference in the electronics.
A red LED (LD2) shows that no servo signals are
present. The reasons fort his may be reception in-
terference, lack of power supply to the receiver ,
switched-off transmitter of contact errors in the con-
nection lines.
