   Tech Tips

   A waterproof connector is used for the television camera assembly, front television camera assembly, side television camera assembly LH or side television camera assembly RH. Therefore, inspect the waveform at the radio receiver assembly with the connector connected.

   
   

   1. Waveform 1 (camera lens is not covered, displaying an image)

      Item	Content
      Measurement terminal	F130-1 (CV+) - F130-9 (CGND) F130-10 (LCV+) - F130-24 (LGND) F130-13 (BCV+) - F130-27 (BGND) F130-4 (RCV+) - F130-18 (RGND)
      Measurement setting	200 mV/DIV., 50 μs./DIV.
      Condition	Ignition switch ON, panoramic view monitor switch on

      Tech Tips

      
      

      • The video waveform changes according to the image sent by the television camera assembly, front television camera assembly, side television camera assembly LH or side television camera assembly RH.

      • The video waveform is constantly output when the ignition switch is ACC.

   2. Waveform 2 (camera lens is covered, blacking out the screen)

      Item	Content
      Measurement terminal	F130-1 (CV+) - F130-9 (CGND) F130-10 (LCV+) - F130-24 (LGND) F130-13 (BCV+) - F130-27 (BGND) F130-4 (RCV+) - F130-18 (RGND)
      Measurement setting	200 mV/DIV., 50 μs./DIV.
      Condition	Ignition switch ON, panoramic view monitor switch on

      Tech Tips

      
      

      • The video waveform changes according to the image sent by the television camera assembly, front television camera assembly, side television camera assembly LH or side television camera assembly RH.

      • The video waveform is constantly output when the ignition switch is ACC.
