Firmware Update
GR-18_3D_jh_V1
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 Download
area for the corresponding products at www.graupner.de.
Connect the adapter lead to the USB interface No. 7168.6. The
connectors are reverse polarity protected: note the small cham-
fers on the sides. Never use force – the connectors should
engage easily.

program from the "Firmware_Up-grade_grStudio" program.
Click on the "Receiver Downloader" item under "Link" in the left
function menu. (Alternatively, select the "Micro Receiver
Upgrade" under "Menu").
It is also possible to start the associated application program
directly. by double-clicking on the file "micro_gyro_swloader.
exe". By double-clicking on the file "micro_gyro_swloader.
exe". You will find this .exe file in the "Graupner_ PC Software"
folder of the "HoTT_Software VX" package.
A program window will now appear in which you should first set
the "correct" COM port for the USB interface No. 7168.6 in the
selection window. (See following picture)
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 alerted to this when you
read out the receiver data). Click on "File" to load the corre-
sponding firmware file named "MicroStabi7X_V_XX.bin" from
the hard disc ("XX" stands for the version number).
