System Connector Interface
System connector
The system connector in RH-6 (and several other DCT-4 products) is called Pop-Port Sys-
tem Connector (unofficial name: "Tomahawk"). It is a galvanic interface between phone
and accessories.
Compared with previous system connector versions, four new functions are introduced
with the Pop-port system connector interface:
•
Accessory Control Interface (ACI)
•
Power Out
•
Stereo audio output
•
Universal Serial Bus (USB).
USB functionality and stereo audio output of the Pop-port are not supported in RH-6.
Note: MBUS function, (included in previous accessory interfaces, e.g. DCT-3) is no more
supported by Pop-port interfaces.
Pop-port system connector is mechanically and electrically not backward compatible
with any earlier Nokia accessory interfaces, except the charger connector.
