Sony Unilink Controlled Wireless MP3Player
Introduction
The Sony Unilink Controlled Wireless MP3Player, has been made due to a convenient problem, basically
because each time i wanted to take some new music with me in my car, i needed to burn a CD with the songs
I wanted to be able to listen to while driving.
As the name says the Sony Unilink Controlled Wireless MP3Player (SUC), is first a interface to communicate
with the Sony Auto Radio, and secondly has a wireless interface (802.11b) via the onboard CompactFlash slot.
With the SUC the MP3Player is from the Sony Radio seen as a CD changer, which it has full control over
this means that the SONY Radio can send its command via the Sony Unilink Protocol to the SUC, fx. when the
user presses 'NEXT', it is send to the SUC and the SUC again can send the infomation about the next song to the
SONY Radio, so using the SONY Radio via the Unilink Control Protocol gives us a 'free' MMI (Man Machine Interface)
which then again means that its not needed any extra keypad nor display in the car everything we need is the
SONY Radio ;-)
Futhermore a server program has been made to support the SUC for file transfering and various house keeping,
which can be perform on the SUC, at last to be named is that the SUC also has a TELNET server where some basic
things can be handeld, primarily setup issues.
