Validating the transmission

Firmware update

18 / 19
The switch settings are serially requested in the transmitter and
transmitted. First when from the switch module has been rec-
ognized the complete data packet, the outputs switch accord-
ing to the switch settings of the transmitter.
Nevertheless interference impulses can lead to error switch pro-
cesses.
To make the switch processes even safer, there is the possibility
in the 16 channel switch module, to compare the related switch
settings from two sequential data packets. Only if the switch set-
tings from two different but consequential data packets match
the channel will be activated.
Through this validation you can have an almost 100% safe
switch of the channel but it will also be slower.
You can activate this function by connecting the X1-9B with
X1-9C.
You can activate this function in parallel with the Fail-Safe func-
tion, all you have to do is to connect all the X1-9 pins to each
other.
The 16 channel switch module has been specifically been devel-
oped for Graupner HoTT 2,4 GHz transmission systems and
needs
no other settings. If you have any question or problem during
the use, please contact us under Hotline service@graupner.
