Audio Data Control Line

The audio data of the snapped in cradle adapter for the mobile phone is controlled by a four-core USB data cable.

The base plate and cradle specifically developed for the Smartphone Integration option (6NF) is immediately recognizable by the two gold-plated pin connectors.

These two gold-plated pin connectors are also used as lock pins for the snap-in cradle adapter.

Plastic pins are used in the same position in the standard snap-in telephone cradle adapters.

In this way it is possible to distinguish at a glance whether the correct base plate is installed for the Smartphone Integration option.
