Wiring method:

Yellow-B + Battery Positive, Black-Gnd Ground, Green-CAN-H, Green with Black-CAN-L, Red RCA-Right Audio Input, White RCA-Left Audio Input

Installation location:

Behind the main unit of the car audio screen, or the car amplifier.

Profession:

Convert the RCA external audio signal into an optical signal, and transmit it to the original car power amplifier through the optical fiber. The sound comes from the original car stereo.

For example: Mercedes-Benz w211 Harman speaker, when the original car screen host needs to be replaced, in order to retain the original car power amplifier, you can choose to install optical fiber speakers. Note that the Mercedes-Benz Bose stereo is not suitable

pay attention:

When you plug in the cable, if the sound is abnormal. Note that this phenomenon is not a problem with our fiber optic conversion modules. This is that the optical fiber communication system of the vehicle cannot communicate normally.

If there is no sound after installing the fiber optic box, please follow the steps below to check:

1: Confirm that the power supply is well connected, measure with a multimeter, yellow---

12v battery power supply, black --- ground wire, no need to connect acc power supply

2: Confirm that the gateway signal is well connected, CAN-H, CAN-L

3: In vehicle optical fiber communication, all optical fiber signals must be able to communicate normally. Due to damage to some electrical equipment in the vehicle,

Optical fiber communication is abnormal. At this time, it is necessary to short-circuit the optical fiber signal of the damaged equipment (common, such as: 6-disc CD, telephone communication module, or directly install the optical fiber audio box to the original car amplifier), so that the original car amplifier and the optical fiber speaker can communicate normally.

4. The W211 amplifier is located on the left side of the trunk of the original car, above the left rear tire, and the W171 amplifier is placed under the cushion in front of the co-pilot of the original car.

method one:

It is necessary to short-circuit the optical fiber signal of the damaged equipment, (common examples: 6-disk cd, telephone communication module, so use the optical fiber shorting ring
