Ensure that the adapter lead is con
fi
gured as shown in the illustrations, and are connected.
Start the Graupner Firmware Update Utility.

and select in the pop-up window „Silicon
Labs CP210x USB to UART Bridge“ and
press „OK“. Select Baud Rate 19200.
Under [Interface Type] click on Signal

*.bin. If everything is correct, the
fi
le will
appear in the corresponding window.
The
fi
rmware
fi
les are encoded in pro-
duct-speci
fi
c form, i.e. if you acciden-
tally select a
fi

the product (e.g. transmitter update
fi
le instead of receiver
fi
le), then the pop-up window “Product code error”
will appear, and you will not be able to start the update procedure.
Press the “Program” button in the software. Wait brie
fl
y until you see movement in the progress bar. This
make take up to
fi
ve seconds, depending on the computer.
Switch on the power supply (see 10.1), so that the General Engine-Module is powered on.
After a few seconds the Status screen displays the message “Found target device…”; you can now release
the button, and the
fi
rmware update process commences.
If the device is not recognised, if the pop-up window “Target device ID not found” appears, or if the process
fails before 100% is reached, you must restart the update procedure. Repeat all the steps as described
above.
The Status display and the Progress bar show the progress of the
fi
rmware update. The update is completed
when the message “Complete…100%” or “Complete!!” appears.
Switch off the power supply and disconnect all leads from the Y-cable. Connect the General Engine-Module
with the receiver again.
