quality and distance. Do not modify the values of these two parameters if you do not
understand their specific meanings.
After entering configuration mode and completing the parameter configuration, be sure to
exit configuration mode.
When you configure P900 version data link system, please strictly follow the picture to
configure the contents, do not modify other values, otherwise the radio may not
communicate normally.
6. The RC Fail-Safe Setting
If the user needs to set the use protection for the remote control, do the following
1)Write Fail-Safe Protection Data
When the airborne unit and ground unit are connected normally, and there is remote control
data transmission, short press the
set
button on the airborne unit (about 0.5S, the L1 and L2
indicators will light up at the same time for about 1S after releasing), then the current remote
control value can be stored in the airborne unit as fail-safe value, and will not be lost after power
failure. Please check whether the fail-safe data is written successfully by testing the flight control,
ground station or servo.
2)Trigger Fail-Safe Protection Value
When the airborne unit does not receive S-BUS data from the ground unit for consecutive 3S, the
airborne unit will keep outputting the previously written fail-safe protection value until it
receives S-BUS data from the ground unit.
3)Close Fail-Safe Protection Data
When the airborne unit and ground unit are connected normally, and there is data transmission
from the remote control, press and hold the set key (≥5S) on the airborne unit until the L1 and L2
indicators are on at the same time (about 1S), turn off the fail-safe data, and the fail-safe data
will not be lost after power failure. Please test if the fail-safe data is off by the flight control,
ground station or servo.
Note
:
By default, there is no fail-safe protection value output from the data link system.
