Electrical Module Description

The Nokia 610/616 RU consist of two PWBs, one large board, designated TF5 and known
as the JB, carries on it all the cable connector sockets and baseband electronics. It has
six external cable connectors for connection of RF antenna, power, audio (2x) and user
interface (2x). It also has several electrical connections to the GSM module (mentioned
below).
Mounted on top, and connected to the JB, is the smaller GSM PWB which is a modified
NPL-1 (6310i) GSM phone module. The GSM PWB is designated TF4 and is known as the
Engine Board (EB). The EB has connections to the JB for control, power, ground and RF
antenna and one connection to the real world for the SIM card interface.
Power supply to the RU is directly from the car battery via an external fuse. There is also
a requirement to monitor the ignition sense (IGNS) signal in the car loom and to have
the ability to mute the car radio.
