or other external RF modules.
To ensure a correct DSC connection, observe the following:
Attention
When your transmitter is directly connected to a desktop computer
by a connecting cable (DSC cable) and/or a computer interface is
connected to your simulator, the transmitter may be destroyed
by electrostatic discharge. This type of connection should therefore
only be used if you protect yourself from electrostatic discharge
while operating the simulator by wearing a commercially available
grounding armband. Graupner therefore strongly recommends
only using wireless simulators.
Perform any necessary adaptations in the menu.
The status LED is constantly red and in the display will appear DSC.
In the upper display appears the transmitter logo.
The transmitter is now ready for use.
Connect the other end of the connecting cable to the device while
observing the relevant operating instructions.
Note
Make sure that all the plugs are securely inserted in the respective
sockets, and only use the provided plug-in connections with a 2-pin
jack plug on the DSC side.

The included memory card is ready for use as soon as the transmit-
ter is switched on. In the display appears the symbol of a memory
card.
Otherwise, folders are created on the memory card ( represented in
the transmitter display by a permanent filling from left to right mem-
ory card). When the animation finishes, the inserted memory card is
ready for use.
You can connect the memory card to your PC by using a memory
card reader. Copy the data downloaded from the transmitter page
on the web site in the related folder of the memory card. Insert the
memory card in your transmitter.
Data recording/Data saving
The data recording in the SD card is linked to the log timer. If it is
started, the data recording starts as well and it stops when the log
timer is stopped.
The data writing on the memory card is remarked by the symbol of
the "filling" of the memory card with black from left to right.
After the installation of the memory card, there is a folder structure
in it. These folders are actually empty.
Finally, the log files are saved in subfolders called "Modelname"
named according to the structure 0001_year-month-day.bin. If a

17 / 40
33028_mc28_T1V3_sh_en
model memory is still nameless, the corresponding log files are
saved in a subfolder entitled "NoName".
In the folder "Models" are saved the exported model memories.
The data can be evaluated on a compatible computer using the pro-
grams found on the downloads page for the transmitter under
www.graupner.de.
