If you you are using a Jeti Duplex 2.4GHz, the “output period” of the receiver must be
set on “byTransmitter” by the Jeti-Box. Other important setting: ATV High Limit: 2,20
ms, ATV Low Limit: 0,80 ms.
One-channel multi-function selection (EKMFA)
To use the EKMFA mode it must be activated in the Sound-Teacher.
With the “One-channel multi-function selection” (EKMFA) you can control up to 30
functions of the SFR-1 with only one proportional channel (channel #3).
You can assign in the Sound-Teacher the functions you would like to trigger with the
EKMFA-mode (see page 66).
To trigger a particular sound or function, the transmitter switch or joy-stick must be
moved from position N to position A or D for a certain number.
The last „function“ is always stored, enabling you to repeat the last sound or the last
function as many times as you wish, without counting once more. Simply hold the
joy-stick for one second in the position B, or C to repeat the last sound.
In order to switch the 16 outputs directly, they must be configured in the Sound-
Teacher as “static“, “flashing“ or “pulse“. An output that is configured e.g. as
reversing or brake light, cannot be switched on.
Sum signals S-BUS and SUMD
With the SFR-1 it is possible to evaluate the sum signals „S-BUS“, „SUMD“ and
„SUMD3“ of the receiver. Up to 16 proportional channels can be transmittet via
only one connection between SFR-1 and the receiver. In order to use sum
signals, the receiver must be suitable for sum signals and an activation in the radio
might be necessay.
Using the sum signal up to 16 fully functional proportional channels, instead of 6, can
be used to control functions.
The sum signal output of the receiver is connected to „Prop 6“ (X2/6) at the SFR-1.
If the SFR-1 receives a correct sum signal, the blue LED will flash at regular
intervals.
Using the Sound-Teacher all 16 channels of the sum signal can be assigned to one
of the 16 propotional channels of the SFR-1.
It is important to use Prop #1 at the SFR-1 for the throttle channel of the transmitter.
