RK3568 high temperature test of ipkvm

1 Introduction

• KVM high temperature test description:
  Place the KVM motherboard in a 50°C incubator for 4 hours. After four hours, record the temperature of the VGA board as well as the SOC temperature and case temperature.

• Test equipment:
  two KVM motherboards, temperature recorder, two serial ports, laptop, power supply

• KVM motherboard power on and serial port
  

• Four places where you want to record the temperature: Glue the four wires of the temperature recorder to these four places. With two boards, there are 8 places. Record the temperature recorder number corresponding to the position of the board
  
  

2. Test steps

• Test tools: two KVM motherboards, temperature tester, two serial ports, laptop, power supply,

• Test steps:

  1. Prepare two KVM motherboards, connect them to the serial port, power supply and temperature tester, and put the two KVM motherboards into the thermostat
  2. Open the MobaXterm software to record the log printing of the test period
  3. The thermostat is heated to 50°C and maintained for 4 hours to see if the serial port can print normally.
  4. After keeping it in a 50°C incubator for 4 hours, check whether there is still printing on the serial port. Record 8 temperatures from the temperature logger.

3. Testing process

• Place the two KVM motherboards into the thermostat
  

• Heat the thermostat to 50°C and maintain the value for 4 hours to see if the serial port can print normally.
  
  

• Record 8 temperatures of the temperature recorder.
