Firmware Update
Updates to the receiver’s firmware are made via the telemetry
socket using a PC running Windows XP, Vista or 7. You will
also need a USB interface (order no. 7168.6) and adapter lead
(order no. 7168.6A or 7168.S), which are available separately.
The programs and files required can be found in the Down-
load area for the corresponding products at
www.graupner.de.
Connect the adapter lead to the USB interface (order no.
7168.6). The connectors are reverse polarity protected: note
the small chamfers on the sides. Never use force – the con-
nectors should engage easily.

Starting the “Slowflyer/Gyro receiver update”
We recommend accessing the “Slowflyer/Gyro receiver
downloader” program from the “Firmware_Up-grade_grStu-
dio” program. Click on the “Receiver Downloader” item under
“Link” in the left function menu. (Alternatively, select the “Mi-
cro Receiver Upgrade” under “Menu”).
It is also possible to start the associated application program
directly by double-clicking on the “micro_gyro_swloader.
exe” file. You will find this .exe file in the “Graupner_ PC Soft-
ware” folder of the “HoTT_Software VX” package. A program
window will now appear in which you should first set the “cor-
rect” COM port for the USB interface (order no. 7168.6) in the
selection window.
If you are not sure which port to use, check the COM port in
the “Select Port” window in the “Menu” of the “Firmware_Up-
grade_grStudio” and note down the COM port number for
the “Silicon Labs CP210x USB to UART Bridge” entry – in this
case “COM03”. (If you select the wrong port, you will be alert-
ed to this when you read out the receiver data). Click on “File”
to load the corresponding firmware file named “MicroStabi7X-
_V_XX.bin” from the hard disc (“XX” stands for the version
number).
