The binding type is indicated in the model memory list near the
model memory name:
"G" means global binding
"M" means model memory specific binding
Module
You can select the fields in the lines with the left and right selection
buttons . In the first "HoTT" field you have the following selection
possibilities:
HoTT - the integrated HoTT module will be used for the signal trans-
mission.
The following settings (EXT. and SP.) are included for eventual exter-
nal RF modules of other manufacturers. They do not work with HoTT
receivers.
EXT. - the signal transmission is emitted through the DSC port to an
optional external RF module. Here the value PPM 10 is set (max. 10
control channels). The "Range test" and "Receiver outputs" func-
tions are not available. Underneath appears a new line. Here you can
set the PPM signal to be emitted normally or inverted.
SP. - The signal transmission will be emitted as a special digital signal
through the DATA port. The binding will be performed through the
"BIND" field. Two new lines will appear underneath. In the first line
the number of the emitted channels
(6 or 8) will be set. In the second line you can set the signal to be
emitted normally or inverted. The "Range test" and "Receiver out-
puts" functions are not available.
If the external RF module has to be powered with the current com-
ing from the DATA port, then pay attention to the following informa-
tion:
Note
The output voltage of the DATA port of about 5 V must be reduced
through a stabilized step-down module to 3 / 3,3 V.
