Figure 5-2 RFC35 connection to J3XX and ACXX
The only way to connect a standard RFC35 to the autopilot is via
the HS+/HS– terminal in J3xx Junction Unit (AP11, AP300X,
AP35, AP20/21/22) and ACXX Autopilot Computer (AP16,
AP25/26/27).
Note RFC35 Fluxgate Compass can also be connected to AP50/J50,
but the compass is not recommended for commercial use!
