Today I have a question about the new MSW expansion module for DC/DS tramsmitters. This module allows connections of more switches and potentiometers to the transmitter via the internal PPM connector. It looks like a very nice device.
My problem is that I already have a device connected to the PPM port in my DC16. This is a headtracker witch is an active device in that sense that it supplies its own power. It is connected via the signal lead to the PPM in pin and the ground lead to the ground pin and it has a voltage of 4,2 V.
And now my question. Can I connect my active, 4,2 v, headtracker device thru one of the six inputs on the new expansion module and still connect other passive switches and potentiometers to the resting five inputs without messing things up?
