1. Q: Thermometry IR thermal camera version, the image is red. How to solve?

It is a temperature alarm, which can be eliminated

Case 1: Use Viewlink software, PWM, S.BUS control

Answer:

(1) Connect serial port, make sure it is well connected.

(2) Send commands “AA 55 0A 96 FF” and “AA 55 0B 43 FF”, and the received feedback commands are same as sent.

Case 2: Use protocol control

Answer: Picture-in-picture switching/color palette switching command, which needs to set the temperature alarm value; the 9^th to 12th byte in the 7E command is the temperature measurement alarm setting bytes, float single-precision floating-point 32-bit (4 bytes, big- endian) is converted into a decimal temperature value, the factory default value is 300° (float: 43 96 00 00)
