Title: Graupner sound switch
Post by: ken224 on May 17, 2012, 07:12:27 am
Hi all
can anyone tell me how to connect my graupner sound switch to my futaba f14, i only want to connect to the seven switch options on the graupner which i believe are negative switches. Unfortunately i can no longer use the proportional channels on the sound switch due to an overload  and a bit of smoke and at the moment i have 8 spare switched channels on my f14

Thanks for that
my main question is what sort of lead or relay do you use to connect from the multiprop decoder to the input clamp on the soundswitch. I am guessing that you use a futaba lead and just connect the ground or am i wrong. dont want another smoke unit  {-)

sorry ken i dont know , the units i have are connected so the -ve runs from a battery to the switcher the switcher then provides all of my components to be turned on / off , the +ve from the battery completes the circuit , the unit itself is pluged into the rx in the same manner a servo would .

Why not give Ripmax a ring. As importers of robbe sets they should be able to help. John.

 Do Robbe importers give out information on Graupner products.  {:-{
