Dedalus autopilot– user's manual

Parallel connection to receiver

Usual remote control receivers with separate outputs of all signals (parallel)
are   connected   with   the   autopilot   in   such   a   way   that   the   outputs   of

appropriate channels of the receiver are connected with the corresponding
input channels of the Autopilot.

NOTE:

 Only first row has pin layout compatible with standard pin connection

sequence   in   receivers   (signal,   power,   ground).   The   remaining   rows   of
connector has 2 inputs and ground on the lower pin.

The RC kits from different manufacturers may use different order of channels
used for functions like ailerons, throttle, elevator or rudder. Pay attention to
the order of receiver outputs and autopilot inputs while connecting channels.

Serial connection of the receiver

If   you   use   a   receiver   equipped   with   serial   PPM   output   (CPPM   or   SBus),
connection of all channels to the autopilot can be made by a single signal 3-
wire   cable   connecting   grounds,   +5V   power   and   receiver   output   signal   to
autopilot input.

Figure 3 Autopilot inputs in serial mode (CPPM, SBus) 

If you connect Serial PPM signal (CPPM), it is necessary to set this option up
up with FPV_manager application on your PC. Please connect autopilot board
to the computer (via USB). Then, in configuration application, choose the
socket pin of the Serial Input PPM (CPPM) - Input 1, and assign channels of
CPPM signal to corresponding functions of the autopilot.

In   serial   mode  you  can  configure  the  unused   PPM   inputs   as   outputs  for
additional   channels   from   CPPM  signal  (output  Aux   2  to  Aux   5,  up  to  11
channels total). This eliminates the need to purchase an additional CPPM
