Frequently Asked Questions about ASA Mercedes MOST>Cinch

What function does the ASA Mercedes MOST>Cinch Adapter serve?

The ASA Mercedes MOST>Cinch Adapter from ACV enables the integration of aftermarket radios into the factory active systems of specific Mercedes models. It ensures that OEM Amplifiers and speakers can still be used by adapting the output signals of the new source to the requirements of the existing system. Signals from the MOST interface are converted to standardized Cinch connections, allowing for a seamless transition between different audio systems. However, it is important to note that some functions, such as the fader or subwoofer settings, may not be supported.

What should be considered when installing the ASA Mercedes MOST>Cinch Adapter?

Before starting the installation of the ASA Mercedes MOST>Cinch Adapter, the system should be checked for functionality. The adapter requires connection to the OEM sound system MOST interface using a red and white Cinch cable. For proper operation, the yellow wire must be connected to +12V constant power (terminal 30), the black to ground (terminal 31), and the red to +12V switched ignition power (terminal 15). Additionally, any OEM additional components such as CD changers or TV tuners that are in the MOST ring should be removed to avoid potential interference.

What limitations does the adapter have regarding the fader function?

The ASA Mercedes MOST>Cinch Adapter does not support a fader function. This is because, when adapting the signals from the MOST interface to the Cinch output, the full functionality of the OEM system cannot be completely replicated. Especially in vehicles with complex sound systems, this can lead to limitations in sound adaptability. For users who rely on the fader function, this means that other hardware or software solutions may need to be considered to meet this need.

Which Mercedes models is the ASA Mercedes MOST>Cinch Adapter compatible with?

The ASA Mercedes MOST>Cinch Adapter is particularly suitable for Mercedes models equipped with the Audio 50 APS Comand NTG2/NTG2.5 navigation systems. It is compatible with vehicles such as the Mercedes CLK-Class (A209/C209) from 04/2005 to 01/2010, the Mercedes CLS (C219) from 04/2008 to 09/2010, the Mercedes E-Class (W211/S211) from 02/2008 to 08/2009, and the Mercedes SLK-Class (R171) from 04/2008 to 03/2011. Models without the mentioned Comand systems or vehicles without the D2B Optical Bus System are not compatible.

What connections does the ASA Mercedes MOST>Cinch Adapter use?

The adapter uses a variety of electrical and optical connections. The primary interface consists of the MOST Bus, a light-based communication standard in the automotive industry. The conversion occurs via Cinch connectors, which are common in retrofit devices. Additionally, loose cables provide the power supply: Yellow for permanent power at terminal 30, Black as ground at terminal 31, and Red for switched ignition power at terminal 15. This combination of optical fibers and electrical connections allows for seamless integration into existing sound systems.

Does the ASA Mercedes MOST>Cinch Adapter need to be tested before final assembly?

Yes, it is essential to test the ASA Mercedes MOST>Cinch Adapter for functionality before the final installation in the vehicle. This ensures that all connections are correct and that the sound system operates properly. A preliminary check can avoid later troubleshooting and potential additional costs. In particular, attention should be paid to the correct signal transmission from the new audio source to the OEM Amplifier. It should also be ensured that no additional OEM components, such as CD changers, cause interference if they have not been removed correctly.

Which components need to be removed from the MOST ring during installation?

During the installation of the ASA Mercedes MOST>Cinch Adapter, some OEM additional components should be removed from the MOST ring to ensure the correct functioning of the adapter. These include CD changers, TV tuners, and telephone modules. Their removal is necessary as they can interfere with signal transmission in the MOST network. If these components remain in the system, it may lead to interference or poor signal transmission. The adapter should also be equipped with a fiber optic connector for the MOST ring (Item: 771000-2100) to complete the circuit.

What are the requirements for connecting the power supply of the adapter?

The power supply of the ASA Mercedes MOST>Cinch Adapter requires special connections to function properly. This includes the yellow wire, which is connected to +12V constant power (terminal 30) to ensure a steady power supply. The black wire represents the ground connection at terminal 31, while the red wire is connected to +12V switched ignition power (terminal 15) as well as Amp Remote or Antenna Remote. This connection configuration allows the adapter to be activated only when the ignition is on, which is energy-efficient.

Why is the fader function not available on the ASA Mercedes MOST>Cinch Adapter?

The fader function is not available on the ASA Mercedes MOST>Cinch Adapter because the adapter primarily focuses on the signal conversion from MOST to Cinch, without retaining full control over the individual audio channels. This functionality is sacrificed in favor of universal compatibility. In retrofit configurations, this results in the loss of the ability to shift the sound image between the front and rear speakers. For vehicle owners who prefer a balanced sound distribution throughout the interior, this could represent a significant limitation that requires alternative audio technologies.

What is the significance of the optical fibers in this system?

The optical fibers in the ASA Mercedes MOST>Cinch Adapter play a crucial role as they form the basis of the MOST communication system. As a light-based transmission technology, they enable fast and lossless signal transmission between the various audio components in the vehicle. The MOST bus uses these optical fibers to transmit audio signals between the head unit and connected systems such as the OEM Amplifier. When using the adapter, these connections must be made through the optical fiber connector (Item: 771000-2100) and the optical fiber loop (Item: 771000-2101) to maintain the signal flow.
