4.2.3 Connecting single line receivers without additional servo outputs
(e.g. PPM composite signal receivers)
For the connection of PPM composite signal receivers there is usually no special adapter required. In
most cases (e.g. Futaba ®-receivers of the SP-series) the receiver can be connected to the MICROBEAST
with one of the supplied regular 3-wire cables. For some receivers, the connecting cable is also already
xed to the receiver (e.g. Jeti ® satellite receiver).
If not xed to the receiver, plug the cable into the output of the digital composite signal of your receiver,
usually labeled with “SIG” or the like. Again pay attention to correct polarity. Be careful, since the sup-
plied cable is designed to be used “universally”, and the usual Futaba® polarity protection tab is mis-
sing.
Plug the other end of the cable into the MICROBEAST input [DI1]. Make sure the polarity is correct; the
orange signal line must be next to the MICROBEAST top cover.
