Q6: How to identify the corresponding directions of various modules used?

A: RadioLink flight controllers PIXHAWK/MINIPIX/TURBOPIX supports 6 SUI04 modules working simutaneously to avoid obstacle from forward/backward/left/right/upward/downward as alt-holding so it needs to be set. Every press on the button, the module direction changes once accordingly clockwise and the module led flahes. Different flash frequencies means different directions. Once-Front, Twice-Right, 3 Times-Back, 4 Times-Left, 5-Times-Downward, 6 times-Upwards. Every direction changed, the flight controller and the module need to be restarted.

 

Q7: What flight mode should be set when using SUI04?

A: When the installation of flight controller is done and data output/displays works,essential flight mode needs to be set.The basic modes includes: 1-Stabliize, 2-Loiter. It's adviced to select Loiter Mode when using the obstacle avoidance function.

 

Q8: Does the memory card need to be taken out when connecting SUI04 to the flight controller?

A:  Yes for MINIPIX and TURBOPIX but no for PIXHAWK. Please take out the memory card when using MINIPIX and TURBOPIX with SUI04.

 

Q9: Can the obstacle avoidance function be activated when setting flight mode as Alt-Hold?

A: Never switch to Alt-Hlod Mode when using the obstacle function. Because at Alt-Hlod Mode, aircraft will keep flying with the commande from the transmitter even obstacle is around and won't stop.  Only when the Loiter Mode is on, aircraft will stop automatically when obstacle confronted, no matter how far the joysticks are toggled. Thus, it's strongly advised to set flight mode as Loiter if avoidance function activated.

 

Q10: How to turn off the obstacle avoidance function?

A: As the function is on at Alt-Hold Mode by default, it needs to be turned off. CONFIG/TUNING- Full Parameter List- AVOID_DIST_MAX,  set the value as 0.
