7. Firmware Update Graupner-HoTT Module M-G2
Firmware updates for the transmitter RF module can be transferred via the DATA or telemetry interface
in conjunction with a PC running Windows XP, Vista or 7. For this you also require the USB interface,
Order No. 7168.6, and the adapter lead, Order No. 7168.6A, which are available separately.
The programs and
fi
les required for this are available from www.graupner.de in the Download area for
the corresponding products.
Install the Firmware Update Utility Graupner and the USB drivers on your computer. Check the system
requirements!
The
fi
rst step is to cut through the central red wire in the adapter lead,
Order No. 7168.6A, then connect the lead to the USB interface, Order
No. 7168.6. This socket is also polarised; note the small chamfer on one
edge. Never use force - the plug should engage easily and fully.
Insert the adapter lead in the DATA socket on the rear of the module, as
shown in the photo. Take care to maintain correct polarity!
For tranmitters with internal telemetry only:
unplug the internal tele-
metry by disconnecting the 3-pin cable with the label MODULE next to
the module M-G2.
