the corresponding pins GND, supply +Ubat and the PPM signal between the transmitter and the IN connector of the
module. Mechanically you may fix the module and the connector either to the transmitter case or the transmitter
tray.
Internal Installation:
Switch off the transmitter and place it on a soft pad in order to prevent mechanical damage. Remove the cover and
before proceeding remove batteries. Select an appropriate location in your transmitter for assembly, keeping
placement of the antenna connector in mind. Mechanical fixing of the module you may acomplish by means of
double sided tape, Velcro fastener or by small screws through holes provided in the module.
For installation of the antenna connector you may usually take advantage of one of the holes provided for additional
switches, the hole for the existing antenna 35/40 MHz, or you may drill a 6,5 mm dia. hole at an appropriate location.
In any case, the part of the connector protruding through the transmitter wall should be long enough (after screwing
the antenna in there must remain at least a small gap between transmitter case and antenna.
On the DUPLEX TU2 module there is a 4-pin connector which connects
the voltage supply and the PPM signal of the transmitter encoder to the
module (see Fig.).
Installation of theTU2 module:
1. Installation of one transmitter module Duplex 2,4GHz.
As far as transmitters of the Graupner MC line are concerned disconnect and remove the FM module and connect the
TU2 module directly to the transmitter encoder by means of the original cable. Some Graupner MC transmitters as
well as other transmitter types are not equipped with standard connectors. In that case you will have to apply the
cable which is contained in Duplex TU2 package or use a special cable as provided in the assembly kit of your actual
transmitter.
2. Installation of two transmitter modules Duplex 2,4GHz with the aid of the assembly kit SWTU-2.
In order to achieve a maximum increase of remote control system reliability you may take advantage of two Duplex
transmitter modules in line with two receiers. For this purpose you need the cable contained in the assembly kit
SWTU-2 which fits transmitters with standard connectors (for instance the Graupner MC line). This cable is also
applicable to other transmitters but it has to be adapted to the actual transmitter configuration or omitted altogether.
