A: No. This SUI04 module is only compatible with the RadioLink flight controllers, CrossRace, CrossFlight, Mini Pix, PIXHAWK, and TURBOPIX.

Attention: the firmware needs to be upgraded to V3.5.7 or above via the links below if works with Mini Pix, PIXHAWK, and TURBOPIX.

A: Make sure that it's the RadioLink flight controller used and the FC firmware is correct so that the module can function.

A:

1) PRX_TYPE value is incorrect. E.g. PRX_TYPE value is set as 4 without SUI04 connected. To turn off SUI04, the PRX_TYPE value should be set as 0.

2) The connection between SUI04 and the flight controller is wrong. Please follow the detailed steps in the user manual via the below link and double-confirm.

A: When the detective distance to the obstacle from SUI04 is less than 40cm, the flight controller cannot be armed. Please move the aircraft away from the obstacle more than 40cm to the arm. So when installing SUI04, make sure to avoid any possible cover on the module such as receiver antenna or GPS.

A: Make sure that the Mission Planner used is the latest version developed by RadioLink. Click the below link to download

A: RadioLink flight controllers PIXHAWK/Mini Pix/TURBO PiX supports 6 SUI04 modules working simultaneously to avoid obstacles from forward/backward/left/right/upward/downward as alt-holding so it needs to be set. With every press of the button, the module direction changes clockwise and the module LED flashes. Different flash frequencies mean different directions. Once-Front, Twice-Right, 3 Times-Back, 4 Times-Left, 5-Times-Downward, 6 times-Upwards. Every direction changed, and the flight controller and the module needed to be restarted.

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

A: Yes, for Mini Pix and TURBO PiX but no for PIXHAWK. Please take out the memory card when using Mini Pix and TURBO PiX with SUI04.

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

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.

A: No. But the direction of SUI04 downward can be setup by pressing the button on SUI04. The corresponding addresses are different in different directions. Each time the button is pressed, the direction of the module changes clockwise, and the module light will flash the corresponding number of times (1 time for front, 2 times for right, 3 times for back, 4 times for left), indicating the current direction.

The addresses in each direction are as follows:

The forward address is 116; the backward address is 114; the left address is 115; the right address is 113; the upward address is 117; the downward address is 112.
