Function:Convert external RCA audio signal to optical fiber signal, and transmit to theoriginal car amplifier through optical fiber. The sound came from the sound of the originalcar. Special attention:when you connect the cable, If the sound is abnormal. Please note that thisphenomenon is not a problem with our fiber conversion module. This is the vehicle's fibercommunication system cannot communicate normally. If there is no sound after installing the fiber optic box,Pls check it as following steps:1: Confirm whether the power supply is connected well, measure with a multimeter, yellow ---battery power 12V, black --- ground wire, no need to connect ACC power supply2: Confirm whether the gateway signal is connected well, CAN-H, CAN-L3:In the optical fiber communication of the vehicle, all the optical fiber signals must be ableto communicate normally. Due to the damage of certain electrical equipment of the vehicle, theoptical fiber communication is abnormal. At this time, it is necessary to short-circuit theoptical fiber signal of the damaged device, (common For example: 6-disc CD, telephonecommunication module, or directly install the optical fiber audio box to the original caramplifier, so that the original car amplifier can communicate with the optical fiber audio boxnormally.4,The W211 power amplifier is located on the left side of the original car's trunk, above theleft rear tire, and the W171 power amplifier is placed under the carpet in front of theoriginal car's co-driverMethod 1: It is necessary to short-circuit the optical fiber signal of the damaged device, (common For example: 6-disc CD, telephone communication module，then Use the fiber short-circuit ring
Method 2: Directly install the optical fiber audio box to the original car amplifier, so that the original car amplifier can communicate with the optical fiber audio box normally.
